Existing +vectors are reused; a new labeled request needs one additional embedding. + +The encoder weights never change. Serving uses **one Qwen4B embedding followed +by a local dot product**, regardless of the number of training labels. One +observed local CPU fit of all four regularization candidates on 512 vectors +took **0.039 seconds**, excluding data loading and embedding collection. + +Production SIE receipts: embedding all 1,152 train/validation/test problems +used **72 batched API calls and 911 credits** (510 development, 401 test). +Two additional single-request production routing checks agreed with recorded +routes and used **2 credits each**. These are observed receipts, not a future +tariff or a promise about an account's free-credit allowance. Feedback acquisition +is separate; this experiment reuses public reference labels. + +## GEPA status + +The reranker is `Qwen/Qwen3-Reranker-4B`; reflection and generative classification +use `Qwen/Qwen3.8-27B-FP8` through production SIE. No GLM, Haiku or Sonnet generated +the reference labels. GEPA 0.1.4 tries 12 description updates, then an 8-update +shared-instruction follow-up. The latter produces no better validation candidate. +The selected reranker loses 0.59 points on test versus the original policy. + +A separate 6-update GEPA run improves the generative rubric's validation accuracy +75.78% → 79.69%, but test accuracy falls **75.78% → 72.46%** (paired difference +−3.32 points, interval −5.86 to −0.59). Optimization used 118 calls and 10,099 +credits; evaluating both frozen teacher policies used 64 calls and 4,393 credits. + +We preserve two discarded teacher attempts: one stopped on incomplete JSON; +another exposed alternating class order in generative batches. The latter was +invalidated before inspecting its test metrics. The corrected run orders batches +by a label-independent hash; a regression test verifies that ordering and score +alignment. Only `teacher/teacher-results.json` is valid teacher evidence. +The earlier `main/teacher-*` and `main/test-teacher/` records are audit-only. + +The original combined success gate required both embedding learning and GEPA to +reduce errors by at least 25%, with positive lower confidence bounds, plus a +GEPA gain of at least 3 points beyond recalibration. **The embedding comparison +passes; the combined gate fails.** Its recorded result remains false.

A cold model or capacity failure can therefore require +rerunning the command. Routing stops at choosing a model; the workshop does +not need paid OpenAI/Anthropic keys. `--answer` is a separate, optional OpenAI +call billed by OpenAI, outside SIE credits. + +For an existing local SIE server, set `SIE_BASE_URL=http://localhost:8080` and +use the same commands.

The scoring instruction stays fixed. GEPA receives +request text, routing decisions, both models' archived grades and costs as +feedback; the reranker itself receives only the request and routing prompt. +The workshop reuses graded answers instead of paying to generate them again. + +The original 729 calibration requests are split deterministically within task +type into 437 training, 146 validation and 146 final threshold-calibration +requests. The initial 64 training examples fit provisional thresholds; the +remaining 373 are available for GEPA reflection. Training utility is cost +saving minus a quality-loss penalty. Validation chooses among accepted GEPA +candidates. A candidate must cost less while retaining at least 98% of strong +quality **and** matching the seed's validation quality. Otherwise retain the +seed. Then freeze selection, recalibrate on the reserved 146, and evaluate on +the original 728 test requests. Test results never select a candidate. + +`plan.json` records the split, objective and budgets before scoring; +`selection.json` records the decision before final calibration/test. +`router.json` contains the selected prompt and cutoff, which may still be the +seed. `calls.jsonl` records billed credits and errors; `scores.jsonl` enables +an offline replay of validation, selection, thresholds and results. Outputs +live under ignored `run-output/`; choose a fresh directory for each run. + +Defaults permit six reflection calls, 5,000 reranker document scores, 1,200 +GEPA metric evaluations, 20,000 **observed** credits and 30 minutes. All apply +together. Requests are sequential, reranking batches up to 32 documents. +Scoring has a 60-second timeout; reflection has 120 seconds and a 1,200-token +output cap. Limits are checked before calls, so a final call can exceed a time +or observed-credit limit. A timeout may have been billed without a receipt. +The failure latch prevents both SDK and GEPA from resending; failures stop the +run and retain receipts. There is no automatic resume of an uncertain run. +Use `--max-reflections`, `--max-score-items`, `--max-credits` and `--max-seconds` +to tighten the budget. `--reflection-model` selects another available SIE model. + +A rejected update is a valid result.

No generated data needs to be committed to Git. + +On October 16, 2026, the corrected run completed in **117 seconds**, with +**75 successful calls, six prompt proposals, 1,832 document/prompt scores and +2,189 credits** (about $0.022 at $0.00001/credit). Both inference roles ran on +SIE. There were no failed calls or retries in this run. The earlier pilot +exposed GEPA's callback retry after a timeout; the failure latch fixes that. +Its separate ledger records 2,704 observed credits and one call with unknown +billing. Two initial capability probes used another four credits. + +Neither update earned promotion: the embedding expansion raised validation +quality but cost more; GEPA's validation candidates sacrificed too much quality. +Both update modes therefore retained their static baselines. On 728 test requests: + +| Router / candidate | Cost / 1,000 | Saving | Quality retained | +| --- | ---: | ---: | ---: | +| Static kNN, 64 examples | $2.38 | 54.2% | 91.7% | +| Expanded kNN, 437 examples, rejected | $2.74 | 47.2% | 93.6% | +| Static reranker / retained after GEPA | $3.03 | 41.7% | 94.2% | + +These smaller-calibration results miss the 98% target. They demonstrate the +feedback loop and why held-out evaluation matters; they do not establish a +winning router or an independent replication of the original study. Serving +model names/profile were fixed, but the cloud API did not pin weight revisions. +Prompt generation is stochastic, so a fresh run can produce different candidates. + +## GEPA improves handler routing + +This separate exercise uses the eight handlers already in `../direct/run.py`: +calendar, calendar updates, meeting schedules, meeting booking, reminders, +reminder updates, to-do lists and to-do updates. Qwen3-Reranker-4B scores each +request against each description; the highest score chooses the handler. +Ties count as incorrect. The unchanged original short descriptions form the +static baseline. This measures intent accuracy, not cheap-versus-strong cost. + +```sh +uv run --frozen python fetch.py --intents +uv run --frozen python replay_intents.py +# Set SIE_API_KEY to run a new experiment; use a fresh output directory. +uv run --frozen --group gepa python intent_gepa.py --output run-output/my-intents +uv run --frozen python replay_intents.py --run run-output/my-intents +``` + +The data is a subset of [CLINC150](https://github.com/clinc/oos-eval/tree/828f8093932c8fe6ca7936c3d2e52903b1c523de), +Larson et al.

There is no normalized exact-text +overlap across these splits. `intent_gepa.py --prepare-source` can rebuild the +subset from the hash-pinned official `data_full.json`. The downloadable archive +includes the source revision, license, subset, prompts, scores and receipts. +The [published run and cost diagnostic](https://huggingface.co/datasets/superlinked/sie-task-evidence/tree/54bda087d98fa2bd7f1883f194cd534276a904b2/evaluations/2026-10-16/request-routing-gepa-improvement-v1) +are pinned by revision and manifest hash in `intent_evidence.py`. + +GEPA 0.1.4 uses Qwen3.8-27B-FP8 on SIE for reflection. It revises one handler +description at a time, receiving training errors and competing descriptions. +The scoring instruction stays fixed. Search utility is accuracy plus 0.05 times +the true-handler score margin. Final selection evaluates every proposal on +validation and maximizes accuracy, breaking ties by shorter total descriptions, +then earlier proposal. It keeps the seed unless accuracy strictly improves. +Selection is written before any test scoring. No test results choose a prompt. + +| Split | Static descriptions | GEPA-selected descriptions | +| --- | ---: | ---: | +| Validation, 160 | 76.25% | 86.875% | +| Test, 240 | 83.33% (200 correct) | 87.50% (210 correct) | + +The October 16 run made 16 reflection calls and 8,128 request/description +scores: **296 successful calls, 349.845 seconds and 4,039 billed credits**. +There were no failed calls. An earlier validation-only baseline check used +180 additional credits and did not inspect test results. GEPA selected four +longer descriptions that distinguish calendar/meeting actions; the reminder +and to-do descriptions remained unchanged. `handlers.json` contains the result. + +The paired gain is **4.17 percentage points**, with 19 corrections and nine +regressions. Replay reports a stratified percentile bootstrap 95% interval of +**+0.42 to +8.33 points** (4,000 resamples, seed 53). The exact two-sided McNemar +test gives **p=0.087**; this small single run is not conclusive evidence of a +general improvement. This task was chosen after cost routing failed to show +a clear gain. The handlers and official test split were not chosen from test +results. Public benchmarks can occur in model training; this is no guarantee +for private traffic. Repeated optimizer seeds and a new temporal test set would +strengthen the result. Do not tune against these now-published test outcomes. + +Live defaults allow 16 reflections, 20,000 document scores, 20,000 observed +credits and 30 minutes. Limits share the failure/receipt protections described +above. `--max-reflections` reduces search and `--reflection-model` selects an +available model. The endpoint/key used here returned `404 model_not_found` for +`zai-org/GLM-5.3-Flash`; no GLM relay was used or verified. Model names/profile +are recorded, but cloud weight revisions are not pinned. Scores for unchanged +descriptions are cached. Eight comparisons are needed per request; this +experiment makes no serving latency or cost advantage claim over classification. + +### Stronger cost-routing diagnostic + +`improve.py` additionally evolves both the cost description and instruction +using training error summaries. It reserves 192 original calibration requests +that were absent from all earlier GEPA scores, then uses 249 for training, +128 for threshold fitting and 160 for validation. Those audit requests were +public and previously used in embedding banks, so this is not independent new +data. Prompt and threshold are both frozen before audit, without recalibration. + +```sh +uv run --frozen python fetch.py --learning --intents +uv run --frozen python replay_improvement.py --run evidence/intents/cost-diagnostic +# Optional fresh cost search, billed to SIE: +uv run --frozen --group gepa python improve.py --output run-output/my-cost-search +``` + +Validation selected a slightly cheaper candidate with no quality regression. +On audit, cost rose **0.32%** ($1.909 → $1.915 per 1,000), while retained quality +rose **94.91% → 96.41%**. Both paired intervals include zero, and the quality +target still fails. This is not a cost-routing improvement. The search stopped +on its 18th reflection attempt after 17 proposals. Its saved candidates were +evaluated in an explicit completion phase, without resending that failed call +or generating more prompts. Total observed credits were 11,677 plus one call +with unknown billing; the complete ledger is retained. The example now limits +reflection feedback to 12 shorter requests and stops promptly on a latched +failure. The archive preserves the actual prompts from the earlier run. + +## What this shows + +Cost routing picks a model for each request before you call one. A request +that a cheap model answers as well as a strong one goes to the cheap model; +the rest go to the strong one. The router has to be much cheaper and faster +than the calls it saves. + +This router embeds the request with `BAAI/bge-m3` on SIE Serverless and finds +the 20 most similar requests in a bank of 729 whose answers from both models +were graded. It weights each neighbour by its cosine similarity and averages +whether the cheap model held up on it. If that score reaches a threshold, the +request goes to the cheap model. The threshold was chosen on the bank to keep +98% of the strong model's quality at the lowest cost. + +On 728 held-out requests, routing between GPT-6 Luna and GPT-6.1 Sol cost +**$3.19 per 1,000 requests, 38.6% less than always using GPT-6.1 Sol at 95.8% +of its quality**. It sent 77.2% of requests to Luna. Between Claude Haiku 5.5 +and Claude Sonnet 5.5 it cost 11.7% less than always using Sonnet, at 99.0% of +its quality. The router itself costs $0.013 per 1,000 requests, included in +those figures. + +| GPT-6 Luna → GPT-6.1 Sol | Cost per 1,000 requests | Saving vs always-Sol | Quality vs always-Sol | Sent to Luna | +| --- | ---: | ---: | ---: | ---: | +| Always GPT-6.1 Sol | $5.19 | — | 100% | 0% | +| **SIE router** | **$3.19** | **38.6% (33.6–44.2)** | **95.8% (93.5–98.0)** | **77.2%** | +| Random routing at 77.2% to Luna | $1.51 | 71.0% | 85.2% | 77.2% | +| Always GPT-6 Luna | $0.42 | 92.0% | 80.9% | 100% | + +| Claude Haiku 5.5 → Claude Sonnet 5.5 | Cost per 1,000 requests | Saving vs always-Sonnet | Quality vs always-Sonnet | Sent to Haiku | +| --- | ---: | ---: | ---: | ---: | +| Always Claude Sonnet 5.5 | $10.36 | — | 100% | 0% | +| **SIE router** | **$9.15** | **11.7% (9.4–14.5)** | **99.0% (97.7–100.3)** | **34.9%** | +| Random routing at 34.9% to Haiku | $6.99 | 32.5% | 93.8% | 34.9% | +| Always Claude Haiku 5.5 | $0.70 | 93.3% | 82.2% | 100% | + +Quality is routed quality as a share of always-strong quality on the same +requests.

They need no +network and no evidence. + +## What this does not establish + +- **Nothing about your traffic.** The requests are benchmark items, and the + saving depends on the mix: the chat stratum is about a sixth of the requests + but most of the always-strong spend, and the strong model wins most of it. + The oracle saving on this mix is 41.6% for the OpenAI pair and 37.5% for the + Anthropic pair. +- **Not the same quality for the OpenAI pair.** It kept 95.8% of GPT-6.1 Sol's + quality, below the 98% target.

Select the cheapest proposal that beats the initial router's cost +and retains at least `max(98%, initial validation quality)`. Otherwise keep the +initial policy. Save the description **and cutoff** before scoring test requests; +there is no post-selection recalibration. The calibration-only arm distinguishes +the effect of new cutoff data from the effect of changing the description. + +The output includes `plan.json`, every proposed description and reflection, +`selection.json`, per-request scores, billed-call receipts, `results.json`, and +the deployable `router.json`. The offline verifier recomputes selection, both +controls, test metrics, paired bootstrap intervals, and credit totals. It rejects +inconsistent recordings. Quality intervals and historical-price limitations +apply to this public benchmark, as in the embedding exercise. + +Default limits are 16 reflections, 16,000 scored request/description pairs, +30,000 observed credits and 30 minutes. `--max-reflections`, `--max-score-items`, +`--max-credits` and `--max-seconds` lower these limits. The credit limit is checked +before each call; one call can cross it. Automatic retries are disabled. A failed +run retains its receipts and `incomplete.json`; a new attempt needs a new output +directory. Failed sends without receipts have unknown billing. + +### Use your own SIE servers + +The same experiment accepts self-hosted SIE endpoints. Serve the reranker's +native `default` CUDA profile and the reflection model's CUDA 13 SGLang profile; +these require separate compatible runtime environments. Set `SIE_BASE_URL` and, +if authentication is enabled, `SIE_API_KEY`. For a separate reflection endpoint, +also set `SIE_REFLECTION_BASE_URL` and `SIE_REFLECTION_API_KEY`. + +Pass `--self-hosted-usd-per-token RATE` to `difficulty.py`, where `RATE` is an +explicit historical USD price per reranker **content input token**. The pinned +study's price is in `evidence/reranker/code/prices.json`. This mode records token +usage, estimates routing cost at that price, and reports Console credits as +not applicable. GPU rental and optimization spend are separate from the +per-request routing estimate. All data splits, selection rules and offline +replay checks remain the same. Do not compare these estimates with a billed +cloud run without accounting for the different cost basis. + +`serve_worker.py` is an optional operator helper for an owned Modal GPU +function.

This does not +establish a material improvement. Against recalibration alone, cost falls +**14.27%** (10.14–19.15%), with **1.71 percentage points lower quality** +(−3.48 to 0.00). That is a cost/quality tradeoff, not a constant-quality saving. +The embedding exercise remains the workshop's stronger measured improvement. + +All three policies were scored in the same self-hosted run. Its new batched +seed scores produce a different cutoff from the earlier archived comparison; +use this run's $3.0788 baseline when assessing GEPA.

Five decisions matched the recorded Cloud vectors; one kNN score +moved from −0.000079 to +0.000017 across the zero cutoff. Replaying recorded vectors +is deterministic; moving a frozen policy to another inference backend needs +validation and, where necessary, new vectors and recalibration. + +## What the measurements mean + +The split contains 512 training, 128 validation and 512 held-out questions. +Routing weights, cutoffs and the primary comparison are frozen before collecting +the held-out answers. All 64/128/256/512-label policies and 1/2/5-percentage-point +validation quality budgets are retained as declared comparisons. The separate +gold-label control measures what the same learner can do with correct labels. + +Answer quality means correctness against the source mathematical answer key, +using the pinned `math-verify` grader and explicit normalization. It is not +agreement with the teacher, routing accuracy, or a judgment by another LLM. +An audit after frozen scoring found that the parser rejected `e^e - 1`, although +it equals the reference `e^{e}-1`. Both models gave that answer to one question. +`economics_scoring.py` applies exact textual equivalence after bracing elementary +single-token exponents and removing whitespace; it retains the original scores +in `economic-results-unadjusted.json` and logs every correction. This adds +0.195 percentage points to every policy's accuracy. All costs, net quality gaps, +paired intervals and policy choices are unchanged. The published figures use +the audited scores, and classroom replay reproduces both stages. +The recorded replay can also print `Timeout during comparison` from the bounded +symbolic grader. The audited expression subtracts a strictly positive sum from +the reference value, so its incorrect score is retained. This is a grading +diagnostic, not an API call or an incomplete replay. +Both lost and gained correct answers are shown. The paired confidence interval +describes uncertainty in the net quality gap; the conservative harmful-switch +bound prevents zero observed losses from being presented as proof of zero risk. + +Dollar amounts convert actual recorded credits at 100,000 credits per dollar. +They describe this recorded experiment, not a promise about future pricing. +Serving totals include actual singleton embedding charges. Training answer +acquisition, batched embeddings and teacher review are reported separately. +Self-hosted teacher GPU cost is not included in Cloud-credit break-even figures. + +The held-out collection encountered one HTTP 500 and retained the original +failure plus one explicitly investigated successful reissue; see +[production issue #800](https://github.com/superlinked/sie/issues/800). +That failed attempt returned no settled credit receipt. Its charge is unknown +and is excluded from the recorded-credit totals; serving comparisons use the +successful paired answers. No failed question is dropped from the evaluation. + +The initial answer prompt was selected using a small training pilot with answer +keys.

To train a new decision function +from reviewed examples, use [Train a router](../train-a-router/README.md). + +For a single native classification call with your own handler labels, see +the [direct routing example](./direct). The recorded cascade below uses a +separate embedding classifier and conditional generation recipe. + +To send each request to a cheap or a strong LLM, see the [cost routing example](./cost). + +Choose a support queue, banking intent, voice-assistant action, or agent route +with an embedding classifier. Send requests below its fixed confidence +threshold to Qwen3.8 27B for a constrained answer. Your application uses the +returned route to decide what happens next. + +The cascade uses two models through `sie_sdk.SIEClient`: + +1. **Qwen3 Embedding 4B** embeds the request. Frozen classifier coefficients + rank the routes. A score of at least `0.29` returns the top route directly. +2. **Qwen3.8 27B** handles the remaining requests. Its prompt includes every + route name and up to ten training examples for each of the ten highest-ranked + routes. A JSON schema restricts the answer to the route list. + +The classifier score is a routing threshold, not a calibrated probability of +being correct. CLINC150 includes `none of these` for out-of-scope requests; +the generation model can choose it. Application handoff or human review is +outside this example. + +## Verify the recorded comparison + +The recorded evaluation uses a fixed 3,000-case subset selected before +inference, with the same cases paired against archived GPT-6 Luna and Claude +Sonnet 5 answers.

All apply -together. Requests are sequential, reranking batches up to 32 documents. -Scoring has a 60-second timeout; reflection has 120 seconds and a 1,200-token -output cap. Limits are checked before calls, so a final call can exceed a time -or observed-credit limit. A timeout may have been billed without a receipt. -The failure latch prevents both SDK and GEPA from resending; failures stop the -run and retain receipts. There is no automatic resume of an uncertain run. -Use `--max-reflections`, `--max-score-items`, `--max-credits` and `--max-seconds` -to tighten the budget. `--reflection-model` selects another available SIE model. - -A rejected update is a valid result.

Refresh the final test set before using its results to -change the method.

No generated data needs to be committed to Git. - -On October 16, 2026, the corrected run completed in **117 seconds**, with -**75 successful calls, six prompt proposals, 1,832 document/prompt scores and -2,189 credits** (about $0.022 at $0.00001/credit). Both inference roles ran on -SIE. There were no failed calls or retries in this run. The earlier pilot -exposed GEPA's callback retry after a timeout; the failure latch fixes that. -Its separate ledger records 2,704 observed credits and one call with unknown -billing. Two initial capability probes used another four credits. - -Neither update earned promotion: the embedding expansion raised validation -quality but cost more; GEPA's validation candidates sacrificed too much quality. -Both update modes therefore retained their static baselines. On 728 test requests: - -| Router / candidate | Cost / 1,000 | Saving | Quality retained | -| --- | ---: | ---: | ---: | -| Static kNN, 64 examples | $2.38 | 54.2% | 91.7% | -| Expanded kNN, 437 examples, rejected | $2.74 | 47.2% | 93.6% | -| Static reranker / retained after GEPA | $3.03 | 41.7% | 94.2% | - -These smaller-calibration results miss the 98% target. They demonstrate the -feedback loop and why held-out evaluation matters; they do not establish a -winning router or an independent replication of the original study. Serving -model names/profile were fixed, but the cloud API did not pin weight revisions. -Prompt generation is stochastic, so a fresh run can produce different candidates. - -## GEPA improves handler routing - -This separate exercise uses the eight handlers already in `../direct/run.py`: -calendar, calendar updates, meeting schedules, meeting booking, reminders, -reminder updates, to-do lists and to-do updates. Qwen3-Reranker-4B scores each -request against each description; the highest score chooses the handler. -Ties count as incorrect. The unchanged original short descriptions form the -static baseline. This measures intent accuracy, not cheap-versus-strong cost. - -```sh -uv run --frozen python fetch.py --intents -uv run --frozen python replay_intents.py -# Set SIE_API_KEY to run a new experiment; use a fresh output directory. -uv run --frozen --group gepa python intent_gepa.py --output run-output/my-intents -uv run --frozen python replay_intents.py --run run-output/my-intents -``` - -The data is a subset of [CLINC150](https://github.com/clinc/oos-eval/tree/828f8093932c8fe6ca7936c3d2e52903b1c523de), -Larson et al.

There is no normalized exact-text -overlap across these splits. `intent_gepa.py --prepare-source` can rebuild the -subset from the hash-pinned official `data_full.json`.

It revises one handler -description at a time, receiving training errors and competing descriptions. -The scoring instruction stays fixed. Search utility is accuracy plus 0.05 times -the true-handler score margin. Final selection evaluates every proposal on -validation and maximizes accuracy, breaking ties by shorter total descriptions, -then earlier proposal. It keeps the seed unless accuracy strictly improves. -Selection is written before any test scoring. No test results choose a prompt. - -| Split | Static descriptions | GEPA-selected descriptions | -| --- | ---: | ---: | -| Validation, 160 | 76.25% | 86.875% | -| Test, 240 | 83.33% (200 correct) | 87.50% (210 correct) | - -The October 16 run made 16 reflection calls and 8,128 request/description -scores: **296 successful calls, 349.845 seconds and 4,039 billed credits**. -There were no failed calls. An earlier validation-only baseline check used -180 additional credits and did not inspect test results. GEPA selected four -longer descriptions that distinguish calendar/meeting actions; the reminder -and to-do descriptions remained unchanged. `handlers.json` contains the result. - -The paired gain is **4.17 percentage points**, with 19 corrections and nine -regressions. Replay reports a stratified percentile bootstrap 95% interval of -**+0.42 to +8.33 points** (4,000 resamples, seed 53). The exact two-sided McNemar -test gives **p=0.087**; this small single run is not conclusive evidence of a -general improvement. This task was chosen after cost routing failed to show -a clear gain. The handlers and official test split were not chosen from test -results. Public benchmarks can occur in model training; this is no guarantee -for private traffic. Repeated optimizer seeds and a new temporal test set would -strengthen the result. Do not tune against these now-published test outcomes. - -Live defaults allow 16 reflections, 20,000 document scores, 20,000 observed -credits and 30 minutes. Limits share the failure/receipt protections described -above. `--max-reflections` reduces search and `--reflection-model` selects an -available model. The endpoint/key used here returned `404 model_not_found` for -`zai-org/GLM-5.3-Flash`; no GLM relay was used or verified. Model names/profile -are recorded, but cloud weight revisions are not pinned. Scores for unchanged -descriptions are cached. Eight comparisons are needed per request; this -experiment makes no serving latency or cost advantage claim over classification. - -### Stronger cost-routing diagnostic - -`improve.py` additionally evolves both the cost description and instruction -using training error summaries. It reserves 192 original calibration requests -that were absent from all earlier GEPA scores, then uses 249 for training, -128 for threshold fitting and 160 for validation. Those audit requests were -public and previously used in embedding banks, so this is not independent new -data. Prompt and threshold are both frozen before audit, without recalibration. - -```sh -uv run --frozen python fetch.py --learning --intents -uv run --frozen python replay_improvement.py --run evidence/intents/cost-diagnostic -# Optional fresh cost search, billed to SIE: -uv run --frozen --group gepa python improve.py --output run-output/my-cost-search -``` - -Validation selected a slightly cheaper candidate with no quality regression. -On audit, cost rose **0.32%** ($1.909 → $1.915 per 1,000), while retained quality -rose **94.91% → 96.41%**. Both paired intervals include zero, and the quality -target still fails. This is not a cost-routing improvement. The search stopped -on its 18th reflection attempt after 17 proposals. Its saved candidates were -evaluated in an explicit completion phase, without resending that failed call -or generating more prompts. Total observed credits were 11,677 plus one call -with unknown billing; the complete ledger is retained. The example now limits -reflection feedback to 12 shorter requests and stops promptly on a latched -failure. The archive preserves the actual prompts from the earlier run. - -## What this shows - -Cost routing picks a model for each request before you call one. A request -that a cheap model answers as well as a strong one goes to the cheap model; -the rest go to the strong one. The router has to be much cheaper and faster -than the calls it saves. - -This router embeds the request with `BAAI/bge-m3` on SIE Serverless and finds -the 20 most similar requests in a bank of 729 whose answers from both models -were graded. It weights each neighbour by its cosine similarity and averages -whether the cheap model held up on it. If that score reaches a threshold, the -request goes to the cheap model. The threshold was chosen on the bank to keep -98% of the strong model's quality at the lowest cost. - -On 728 held-out requests, routing between GPT-6 Luna and GPT-6.1 Sol cost -**$3.19 per 1,000 requests, 38.6% less than always using GPT-6.1 Sol at 95.8% -of its quality**. It sent 77.2% of requests to Luna. Between Claude Haiku 5.5 -and Claude Sonnet 5.5 it cost 11.7% less than always using Sonnet, at 99.0% of -its quality. The router itself costs $0.013 per 1,000 requests, included in -those figures. - -| GPT-6 Luna → GPT-6.1 Sol | Cost per 1,000 requests | Saving vs always-Sol | Quality vs always-Sol | Sent to Luna | -| --- | ---: | ---: | ---: | ---: | -| Always GPT-6.1 Sol | $5.19 | — | 100% | 0% | -| **SIE router** | **$3.19** | **38.6% (33.6–44.2)** | **95.8% (93.5–98.0)** | **77.2%** | -| Random routing at 77.2% to Luna | $1.51 | 71.0% | 85.2% | 77.2% | -| Always GPT-6 Luna | $0.42 | 92.0% | 80.9% | 100% | - -| Claude Haiku 5.5 → Claude Sonnet 5.5 | Cost per 1,000 requests | Saving vs always-Sonnet | Quality vs always-Sonnet | Sent to Haiku | -| --- | ---: | ---: | ---: | ---: | -| Always Claude Sonnet 5.5 | $10.36 | — | 100% | 0% | -| **SIE router** | **$9.15** | **11.7% (9.4–14.5)** | **99.0% (97.7–100.3)** | **34.9%** | -| Random routing at 34.9% to Haiku | $6.99 | 32.5% | 93.8% | 34.9% | -| Always Claude Haiku 5.5 | $0.70 | 93.3% | 82.2% | 100% | - -Quality is routed quality as a share of always-strong quality on the same -requests.

The figures below describe the dated recorded study. + +## What this shows + +Cost routing picks a model for each request before you call one. A request +that a cheap model answers as well as a strong one goes to the cheap model; +the rest go to the strong one. The router has to be much cheaper and faster +than the calls it saves. + +This router embeds the request with `BAAI/bge-m3` on SIE Serverless and finds +the 20 most similar requests in a bank of 729 whose answers from both models +were graded. It weights each neighbour by its cosine similarity and averages +whether the cheap model held up on it. If that score reaches a threshold, the +request goes to the cheap model.

The chat judges seldom called ties. +- **Latency elsewhere.** Router latency was measured from one client host. +- **Prices other than list prices.** Caching and batch discounts were not + applied. diff --git a/examples/request-routing/cost/check_posttrain_serving.py b/examples/request-routing/cost/check_posttrain_serving.py deleted file mode 100644 index 96d56e83d..000000000 --- a/examples/request-routing/cost/check_posttrain_serving.py +++ /dev/null @@ -1,128 +0,0 @@ -"""Verify native SIE Laya export and measure matched local adapter latency. - -Run in an installed SIE server environment, after posttrain.py evaluate. -This is an optional GPU check, independent of the CPU workshop environment. -""" - -from __future__ import annotations - -import argparse -import gc -import json -import time -from pathlib import Path - -import numpy as np - - -def main(): - import torch - from sie_server.adapters.laya.adapter import LayaAdapter - from sie_server.adapters.laya.questions import Calibration - from sie_server.adapters.pytorch_embedding import PyTorchEmbeddingAdapter - from sie_server.types.inputs import Item - - parser = argparse.ArgumentParser(description=__doc__) - parser.add_argument("--run", type=Path, required=True) - parser.add_argument("--evaluation", type=Path, required=True) - parser.add_argument("--questions", type=Path, required=True) - parser.add_argument("--latency-only", action="store_true") - parser.add_argument("--output-name", default="sie-serving.json") - args = parser.parse_args() - output = args.run / args.output_name - if output.exists(): - raise FileExistsError(output) - torch.set_num_threads(8) - torch.set_num_interop_threads(1) - frozen = json.loads((args.run / "frozen.json").read_text()) - evaluation = json.loads((args.run / f"evaluation-{args.evaluation.stem}.json").read_text()) - rows = json.loads(args.evaluation.read_text()) - questions = json.loads(args.questions.read_text()) - results = { - "device": torch.cuda.get_device_name(), - "precision": "bfloat16 CUDA projections", - "torch_threads": torch.get_num_threads(), - "scope": "Direct native SIE adapters;

This removes detected leakage; it does +not establish that paraphrases are all detected or that foundation-model +pretraining excluded these public mathematics problems. + +The sampling/target protocol was fixed before new test predictions. All eight +embedding policies and both native training families at seeds 89, 137 and 211 +are reported. There is no test-based choice of seed, family, threshold or budget. +The test is now a public regression benchmark; further development should use a +new prospective test population for a new generalization claim. + +## Models and selection + +**kNN:** frozen Qwen3-Embedding-4B produces a normalized 2,560-dimensional vector. +The five most similar training vectors vote. More labels grow the bank; encoder +weights never change. + +**Ridge:** the same vector feeds 2,560 learned weights and a bias. There are no +hidden layers. Training minimizes squared error with L2 regularization; +validation MSE chooses among 0.01, 0.1, 1 and 10. Calibration chooses the cutoff +by balanced accuracy. Scores can fall outside [0, 1] and are not probabilities. + +Growing the ridge training set does not add inference calls: serving still uses +one embedding and 2,561 local coefficients. Feedback collection and retraining +are separate, one-time costs. kNN instead keeps a larger example bank. Neither +approach changes the embedding model's per-request computation as labels grow. + +**Laya:** a 421M-parameter ModernBERT-large encoder plus a native decision head +scores a typed two-option question without generating text. Full fine-tuning +updates the complete checkpoint. LoRA trains rank-16 adapters on encoder +attention `Wqkv`/`Wo` **and the entire decision head**: 29.3M trainable parameters, +including 2.75M encoder adapter parameters. This is not head-only training. +Adapters are merged into an ordinary Laya checkpoint for serving. + +Every native run uses eight epochs and the same data order seed, effective batch +16, 512-token input limit and 256-token question budget. Validation cross-entropy +selects an epoch; a separate calibration partition selects the cutoff by balanced +accuracy on the serialized checkpoint. Full encoder/head learning rates are +2.5e-5/1e-4; LoRA uses 2e-4/1e-4. +The comparison evaluates these declared recipes, not the best possible fully +tuned recipe for each architecture. Three seeds are a stability check, not an +exhaustive hyperparameter search. + +## Static and improving versions + +Each deployed policy is static: its bank or weights and its cutoff are frozen. +An update collects reviewed examples, retrains on training data, selects using +development data, freezes a new version, and evaluates it. Improvement is a +measured outcome, not an automatic property of adding examples. The nested +budgets illustrate that process without changing the test population. + +If human labels are unavailable, a teacher can supply candidate labels, but +teacher agreement alone does not establish correctness. Keep a separately +human-reviewed validation/test sample and measure teacher errors before replacing +the benchmark's labels. No teacher or GEPA supplies labels in this example. + +Accuracy and balanced accuracy are reported alongside false-routine and +false-advanced counts.

A [second single-seed comparison](https://github.com/NandhaKishorM/laya/issues/741) also favors soft CE; these do not establish a consistent advantage. | +| [Later three-seed loss comparison](https://github.com/NandhaKishorM/laya/blob/main/research/scripts/step4_benchmark/GATE_D_RESULTS.md) | Same pinned training contract and teacher distributions; only the loss changes, across seeds 0, 1, and 2. | Mean accuracy: RLCD .7762, soft CE .7763. The paired difference changes sign; seed standard deviation is .0016 versus .0155. The authors retain RLCD as the default. Neither objective has a demonstrated mean-accuracy advantage here. | +| [Community QQP LoRA](https://github.com/vishalmysore/layaMOE/blob/main/results/qqp_lora.json) | Start from `laya-typed-decisions`; 1,500 duplicate-question pairs; rank 16 adapters in the last four encoder layers, attention and MLP; train the native head too. | Accuracy 77.2% → 78.0%; F1 .767 → .791. Reported McNemar p=.299: a working recipe, without a statistically established accuracy gain. | +| [Browser decision model](https://github.com/NandhaKishorM/laya/blob/main/docs/finetune_browser_agent.md) | Thousands of browser states and goals, successful actions and trajectory negatives; full tuning; revise candidate representation to avoid truncation. | The walkthrough reports element selection around 10% → 66% on held-out pages. This is a narrower task than complete browser-task success; later model versions and harnesses have different results. | +| [DynaSent and SNLI](https://github.com/rsk2327/decision-model-benchmarks) | Full tuning of `laya-multilingual` on 80,488 sentiment examples or 100,000 inference examples; development data for calibration, followed by frozen test evaluation. | Reported macro F1: DynaSent .4524 → .7558; SNLI .8593 → .8824. These use a different base checkpoint, different tasks, and much more training data than this router. | + +The [QQP notebook's code](https://github.com/vishalmysore/layaMOE/blob/main/notebooks/laya_lora_qqp.ipynb) +adapts `attn.Wqkv`, `attn.Wo`, `mlp.Wi`, and `mlp.Wo` in layers 24–27, with +rank 16, alpha 32, dropout .05, both learning rates 2e-4, batch 16 and three +epochs. It holds out 150 of the 1,500 generated training pairs for validation, +uses ordinary hard-label cross-entropy, AdamW with weight decay .01, and a +6% warmup followed by linear learning-rate decay. Our `top-layers` candidate isolates +attention-layer scope using the same slower settings as our `slow` candidate. +It is inspired by that example, not a reproduction of its recipe or checkpoint. +The [QQP input builder](https://github.com/vishalmysore/layaMOE/blob/main/scripts/gen_qqp_data.py) +also uses a boolean `noul` question with three instruction wordings, whereas +this router uses one fixed two-option `choice` rubric. That is a separate input +design choice, not an incompatibility between the checkpoints. + +## Checkpoint and input differences + +The [English checkpoint configuration](https://huggingface.co/convaiinnovations/laya/blob/aa8c91ca088ec597df95a0d1c76b3063cb2ae5e8/rl_agent_config.json) +and [typed-decisions configuration](https://huggingface.co/convaiinnovations/laya-typed-decisions/blob/main/rl_agent_config.json) +both specify ModernBERT-large and two native head layers. Their default input/head +budgets differ: 512/192 for English, 1,024/256 for typed-decisions. This example +explicitly uses 512/256. Both accept the same typed `state` and `questions` +contract; typed-decisions is not a different classifier architecture. + +The [typed-decisions model card](https://huggingface.co/convaiinnovations/laya-typed-decisions) +describes additional training on four synthetic business workflows. It cautions +that unrelated tasks can perform like the English base or worse. Starting from +that checkpoint is therefore a separate transfer-learning candidate, not an +established upgrade for mathematics difficulty. + +## Decisions for this example + +Retain supervised cross-entropy as the simplest controlled objective for this +experiment. The later three-seed panel qualifies the early single-seed wins: +mean accuracy is essentially equal, while RLCD is more stable in that reported +full-fine-tuning experiment. It does not show that CE is superior, or that RLCD +will improve this binary LoRA router. + +The [training loader](https://github.com/NandhaKishorM/laya/blob/main/laya/train.py) +supports both `gold` probability targets and one-hot `expected` labels with the +same soft cross-entropy objective. +The loss comparisons above keep the same teacher distributions; they are not +soft-target versus hard-target ablations. Our examples have hard human +difficulty labels. Label smoothing is explicit regularization, not a teacher's +estimated probability distribution, and the QQP LoRA example also uses hard +labels. None of these sources establishes that buying teacher probabilities is +necessary for this task. + +Test adaptation capacity and more data. The original recipe trained the whole +native head alongside encoder adapters. New candidates slow the updates, +regularize them, freeze the head, train only the scorer beside the adapters, +or restrict adapters to the last four encoder layers. Then the +validation-selected recipe gets all 2,581 eligible training families instead +of 512. No new teacher calls are needed for this particular dataset. + +Finish that declared study before adding candidates. If another recipe is +needed, the attention-plus-MLP scope and warmup in the actual QQP code are +concrete, inexpensive changes to investigate on development data. Keep the +English base fixed when testing those changes; a checkpoint change is a separate +factor. The public QQP result supports feasibility, not an expected accuracy +gain on this dataset. + +Select checkpoints for the routing decision. Validation ranking continued to +improve after raw cross-entropy deteriorated in the initial runs. The follow-up +therefore selects maximum validation ROC AUC, retaining the earlier epoch on +ties, and fits the decision cutoff on separate calibration data. It retains +cross-entropy and training loss as diagnostics. AUC selection is a declared +protocol change; the original CE-selected results remain available. + +## Keep the evaluation boundaries + +The [typed-decisions dataset card](https://huggingface.co/datasets/LocalLLaMA/typed-decisions) +describes teacher-generated labels. Teacher agreement is a different claim +from independently verified business outcomes. A teacher self-agreement +statistic is not a mathematical ceiling on a student's score. + +The [official notebook](https://github.com/NandhaKishorM/laya/blob/main/notebooks/laya_finetune_typed_decisions_2xT4_kaggle.ipynb) +splits calibration after flattening cases into decisions; sibling questions +can therefore appear in both training and calibration. This does not itself +establish test leakage. We retain this example's stricter grouped, +chronological partitioning and pinned inputs. We also measured truncation: +only 9/512 training and 4/247 validation examples exceed the native input +budget, so context length is not the first intervention. + +The already-published 479-case test is an **exposed regression benchmark** for +this follow-up. New recipes are chosen without its outcomes, but a fresh +temporal generalization claim still requires additional evaluation data. diff --git a/examples/train-a-router/docs/lora-study.md b/examples/train-a-router/docs/lora-study.md new file mode 100644 index 000000000..d3e44950e --- /dev/null +++ b/examples/train-a-router/docs/lora-study.md @@ -0,0 +1,327 @@ +# LoRA follow-up: select a recipe, then add training examples + +This optional study tests the capacity and regularization of the native Laya +router, then increases its training data.

The five new recipes +freeze the unused action head. Label smoothing applies only to training targets. +Native-head dropout remains active during training, including in frozen-head +runs; evaluation disables dropout. The [source review](laya-adaptation.md) +explains the motivation and differences from public Laya adaptation recipes. + +Selection has three separate steps: + +1. Train each of the six recipes on 512 examples for seeds **89, 137, and 211**. + For each run, choose the maximum ROC AUC on the 2018 validation set. Epoch zero + is eligible; ties retain the earliest epoch. Cross-entropy and training loss + remain diagnostics. +2. Choose the recipe with the highest mean selected validation AUC across all + three seeds. Ties retain recipe declaration order, shown in the table. Write + `recipe-frozen.json` before starting the larger training runs. +3. Train that same recipe on 2,581 examples for all three seeds, with unchanged + learning settings. For every selected checkpoint, fit its cutoff by balanced + accuracy on the separate 2019 calibration set. Calibration does not choose the + recipe or epoch. Write `all-frozen.json` when every run is complete. + +The 18 screening runs plus three expanded runs are all retained. No best seed +is selected. The driver checks that both training directories have identical +validation, calibration, and question files, and that the smaller training file +is the exact prefix of the expanded one. It never reads test inputs. + +Keeping eight epochs also increases the training budget: 512 examples produce +256 optimizer updates, while 2,581 produce 1,296. This compares the practical +recipe of adding examples and training for the same number of passes; it does +not isolate dataset size at fixed compute. + +## Why this study exports FP32 weights + +The original Laya serializer writes half-precision weights. In the first +follow-up attempt, that conversion changed validation logit margins beyond the +declared export tolerance. Before recipe selection or test evaluation, the +study was amended to preserve FP32 weights for every candidate. The initial +attempt is retained as an audit; the training recipes and data did not change. + +The study passes `--export-dtype float32` to `finetune.py`. This changes the +saved checkpoint precision, not the training objective or native architecture. +Encoder adapters are merged, validation margins are checked before and after +merge and export, and calibration uses the reloaded exported checkpoint. All +follow-up candidates use the same export rule. The original baseline keeps its +original export and selection protocol. Consequently, the historical CE baseline +versus the new original-recipe AUC control changes both checkpoint selection and +export precision. That comparison cannot attribute a difference to selection +alone. Recipe and training-size comparisons within the new study all use FP32. + +## Evaluate only after the study is frozen + +Wait for `ALL_LORA_RUNS_FROZEN` and `run-output/my-lora-study/all-frozen.json`. +Then make the original evidence available on the evaluation machine and run: + +```sh +uv run --frozen --group training python lora_evaluate.py \ + --study run-output/my-lora-study --evidence evidence \ + --device cuda --timeout-seconds 1800 +uv run --frozen python lora_report.py \ + --study run-output/my-lora-study --evidence evidence \ + --output run-output/my-lora-report.json +``` + +The evaluator checks the completed study and development selections, then sets +`TORCH_COMPILE_DISABLE=1` and `TORCHDYNAMO_DISABLE=1` before loading any model. +Each frozen checkpoint must reproduce its selected validation scores and saved +calibration scores within a maximum absolute margin difference of **0.03**, with +**zero changed decisions** at its existing cutoff on both splits. These checks +run in isolated processes under the same overall timeout. The declared checks, +per-checkpoint scores, and completion hashes are saved in `runtime-parity` +receipts. A failed check stops the run before test inputs are opened. + +In the recorded run, all six checkpoints passed: maximum development-margin +drift was 0.000174, with no changed decisions. The first evaluation attempt had +produced a plan but no outcome files during a prolonged startup. That plan and +the runtime amendment are retained in the public audit. The startup cause was +not localized; disabling compilation did not eliminate the initial delay. + +After every checkpoint passes, it evaluates the original recipe at 512 examples, the +selected recipe at 512, and the selected recipe at 2,581, each for all three +seeds. If the original recipe wins, its 512-example stage is evaluated once. +Existing parity and evaluation outputs are preserved; rerunning an interrupted +attempt in place is refused. The runtime change keeps weights and cutoffs fixed; +latency measurements from eager and compiled execution are different comparisons. +Fresh GPU evaluation needs the +trained weights; downloading only the published core records supports CPU report +replay instead. + +The report compares these stages with the original CE-selected native runs and +the unchanged `ridge512` embedding reference. The published test is an **exposed +regression benchmark** in this follow-up. Development selection is separate from +its outcomes, but a new claim about future generalization requires a new test +population. Difficulty accuracy alone does not establish downstream answer +quality or monetary savings; those need paired solver outcomes and serving costs. diff --git a/examples/train-a-router/docs/results.md b/examples/train-a-router/docs/results.md index 8c53a17ac..d0e17a811 100644 --- a/examples/train-a-router/docs/results.md +++ b/examples/train-a-router/docs/results.md @@ -34,7 +34,7 @@ would need a different development criterion and its own evaluation.

The labels—the expected routine/advanced categories -used for training and evaluation—come from human difficulty ratings in -[Easy2Hard-Bench](https://huggingface.co/datasets/furonghuang-lab/Easy2Hard-Bench), -using each competition's historical median rating as the dividing line. These -categories describe difficulty **within a competition**. The model sees only -the problem and competition name; it never receives the answer, solution or -rating as input. +Follow these five steps.

The embedding experiment also uses smaller subsets. | -| Validation | 247 | Choose training settings or which saved model version to keep. | -| Calibration | 246 | Choose the score cutoff that separates routine from advanced. | -| Test | 479 | Measure the selected model after its settings are fixed. | - -Older problems are used for development and newer problems for testing. Copies -and near-duplicates of a problem are kept from crossing those groups. See the -[data checks](docs/methodology.md) for the exact construction. - -- **Accuracy:** correct routine/advanced decisions divided by all 479 test - problems. This is the quality metric in the step headings. -- **Balanced accuracy:** average of the success rate on routine problems and - the success rate on advanced problems, giving both groups equal weight. -- **Error counts:** an advanced problem labeled routine may receive too little - computation; a routine problem labeled advanced may receive more than it - needs. We report both mistakes separately. -- **Validation AUC:** measures how well scores rank advanced problems above - routine problems, before choosing a cutoff. Laya training uses it to select the - saved model; it is separate from the accuracy reported in the headings. - -The scripts print accuracy as a fraction; the headings show percentages. -Training records also report elapsed time, and Cloud requests save a record of -API usage and charges. Those measurements are separate from classification quality. - -The bracketed accuracies are recorded references. LoRA training was repeated -with three random seeds (89, 137 and 211), which change initialization and -training order; the headings show their average. The commands below run seed -89 once. Hardware can also affect your result. This public test set has already -been used in several experiments, so it is useful for reproducing these results -but is no longer a previously unseen final exam for new research. Model sizes -and training budgets differ; [results](docs/results.md) and -[methodology](docs/methodology.md) explain the limits of the comparison. - -## What you will build - -1.

[Compare the 512-example embedding classifier [72.03%]](#5-compare-the-512-example-embedding-classifier-7203). - -## Prerequisites and shared setup - -Use either an **Apple Silicon Mac** or an **NVIDIA GPU**, on your own computer -or a rented GPU machine, for the Laya stages. Install Git and -[uv](https://docs.astral.sh/uv/getting-started/installation/), which installs -Python and the example's dependencies. Allow disk space for several saved model -versions, also called **checkpoints**. Choose `mps` for Apple's GPU support in -PyTorch, or `cuda` for NVIDIA's. See [Mac setup and measurements](docs/mac-training.md) -for tested hardware and software. The reference accuracies above were measured -on an NVIDIA H100. -On an M3 Max, the complete 512-example Mac run took **10.3 minutes** and reached -**57.62%** accuracy, with **9.1 GiB** peak sampled GPU allocation. That machine -had 128 GiB unified memory; smaller-memory Macs have not been validated. -The full 2,581-example Mac training run has not yet been measured. - -The embedding-classifier stages run on **CPU** using previously computed Qwen -embeddings: lists of numbers that represent each problem's text. For a new -request, those numbers must be computed by SIE Cloud or your own server. A SIE -Cloud key lets you call a hosted model; you still need your own GPU machine for -the Laya training steps. - -Start in the root of your cloned repository. This creates the example's Python -environment with the exact dependency versions recorded in `uv.lock`; -`--group training` includes the packages needed for LoRA training: +| Original training set | 503 | Fit a router with a modest labeling budget. | +| Expanded training set | 2,503 | Add examples from the same training competitions and years. | +| Calibration | 242 | Choose when the stronger model is worth its extra cost. | +| Main test | 463 | Measure the saved decisions on later competition problems. | + +Separate training exam papers select training settings. Calibration chooses +the **cutoff**, the score above which a request goes to the stronger model. +The models and cutoffs are saved before examining test answers. Duplicate +families stay out of different groups. This separation covers our router's +training; we cannot establish what the original models saw during pretraining. +After exploratory training, we amended the source review to exclude +missing-context questions and correct references, before opening the held-out +answer-model results. The downloadable review records those decisions. + +- **Answer accuracy:** percentage of correct final answers. Equivalent forms + such as `1/2` and `0.5` count as the same answer. +- **Quality gap:** always-strong accuracy minus routed accuracy, in percentage + points. A change from 90% to 89% is a **1-point** gap, or 100 fewer correct + answers per 10,000 requests. We also count answers recovered when the smaller + model succeeds and the stronger one fails. +- **Cost per 10,000 requests:** the selected answer-model charges plus the known + cost of deciding where to send each request. +- **Savings:** the reduction from the always-strong bill. A drop from $100 to $70 + per 10,000 requests is **30% savings**. For locally hosted Laya, we report + answer-model savings and the remaining allowance for router hosting; its + unmeasured hosting cost is not treated as zero. + +The primary setting allows a **1-point gap on calibration**, then measures the +actual test gap. The 463-question test cannot establish a guaranteed 1-point +gap on future requests. The report also keeps 0-, 2-, and 5-point targets and +shows 95% uncertainty intervals, estimated by resampling questions while +keeping each pair of model answers together. Dollar tables scale the +recorded workload to 10,000 requests; the JSON retains per-1,000 values. + +## Setup + +Install Git and [uv](https://docs.astral.sh/uv/getting-started/installation/). +**CPU is sufficient to replay every recorded result and fit the embedding +classifiers. To perform the LoRA stage yourself, use an NVIDIA CUDA machine**, +locally or rented, including a Modal GPU shell. The reference uses an H100. +Run the training commands inside that machine's checkout; SIE Cloud supplies +inference, while your GPU machine performs training. + +From the root of a clone of this repository: ```sh -# Enter the example, select your GPU, and install the recorded dependencies. +# Enter this example and install the locked CPU replay and classifier dependencies. cd examples/train-a-router -export ROUTER_DEVICE=mps # Apple Silicon; use cuda for an NVIDIA GPU -uv sync --frozen --group training +uv sync --frozen --group outcomes ``` -Download the data, precomputed embeddings and recorded reference results.

These commands copy data; they do not train a model: +`evidence/` holds references; `run-output/` holds your results. Repeated runs +need fresh output directories. -```sh -# Prepare training inputs while keeping test problems out of both folders. -mkdir run-output/lora-small-inputs run-output/lora-expanded-inputs -cp evidence/train.jsonl evidence/validation.jsonl evidence/calibration.jsonl \ - evidence/questions.json run-output/lora-small-inputs/ -cp evidence/validation.jsonl evidence/calibration.jsonl evidence/questions.json \ - run-output/lora-expanded-inputs/ -cp run-output/lora-study/expansion/train-expanded.jsonl \ - run-output/lora-expanded-inputs/train.jsonl -``` +**PENDING publication:** the download command is implemented but its final +Hugging Face revision and manifest must be pinned before this draft is released. -The data and recordings total about 28 MB. Training downloads the model weights -separately. `evidence/` holds downloaded reference files; `run-output/` holds -your inputs and results. Use a new output directory when repeating a training -run, so the previous run remains intact. All code lives in this example; large -data and model files live on Hugging Face. + -## 1. Measure calibrated Laya [53.65%] +## 1. Establish the always-strong baseline [savings 0%; quality gap 0 points] -**Apple or NVIDIA GPU.** Laya has about 421 million learned values, called model -weights, and is built on the ModernBERT text model. It scores the two choices defined in -`evidence/questions.json`. First, leave its weights unchanged and use the -calibration examples to choose a score cutoff. Then measure its test accuracy: +**CPU.** Recompute the complete comparison from saved answers and decisions. +This makes no model calls and needs no API key. ```sh -# Choose a cutoff for unchanged Laya weights, then measure test accuracy. -uv run --frozen --group training python finetune.py train \ - --data run-output/lora-small-inputs --output run-output/my-base \ - --variants base --seed 89 --device "$ROUTER_DEVICE" -uv run --frozen --group training python finetune.py evaluate \ - --evaluation evidence/test.json --questions evidence/questions.json \ - --output run-output/my-base --device "$ROUTER_DEVICE" +# Recompute the cost and answer-quality tables from the downloaded evidence. +uv run --frozen --group outcomes python router.py replay \ + --study evidence --output run-output/replay ``` -Read `run-output/my-base/evaluation-test.json`. This measures the starting -decision model with a calibrated cutoff; it performs no weight updates. +Open `run-output/replay/comparison.md`. The first row sends every question to +Qwen 27B: accuracy **PENDING**, cost **PENDING per 10,000 requests**. The +always-Qwen-4B row shows the cheapest fixed choice and its quality gap. -## 2. Adapt Laya on 512 examples [57.34%] +Every router selects between the same two recorded answers per question. +The main comparison uses measured SIE Cloud answer charges; replaying it adds +no inference cost. -**Apple or NVIDIA GPU.** **LoRA** adapts a model by training small added weight -updates while keeping most of the original model fixed. This recipe also trains -Laya's final decision layers, which turn its text representation into option -scores. Make eight passes through the training data (eight **epochs**).

Use Laya [answer cost savings PENDING; quality gap PENDING] -The recorded NVIDIA H100 run with seed 89 scored **57.41%**; the heading gives the three-seed -mean. Training combines the learned updates with Laya's original weights and -saves the result in `run-output/my-lora512/lora/`. It writes `frozen.json` to -record the selected model and cutoff before test evaluation; test results go -to `run-output/my-lora512/evaluation-test.json`. The commands export weights as -32-bit numbers (`float32`) to avoid rounding them to a lower-precision format. -Calibration checks this saved version before choosing its cutoff. The -[training guide](docs/lora-study.md) explains the settings. +**CPU for replay; optional local CPU or NVIDIA GPU for new decisions.** Laya +is a decision model: it scores choices instead of writing a full answer. +Here it estimates each answer model's chance of being correct. Compare the +**Laya unchanged** rows in the report from step 1. -## 3. Expand LoRA training to 2,581 examples [65.00%] +Its weights remain unchanged. Training examples supply expected costs, and +calibration sets the cutoff. Laya has roughly 421 million parameters—the +numerical weights stored in a model. -**Apple or NVIDIA GPU.** Keep the recipe and change the training data. The first 512 rows are -unchanged, as are validation, calibration and test. Keep these settings fixed -through the walkthrough rather than adjusting them after inspecting test errors. + -```sh -# Repeat the same training recipe with 2,581 examples and measure its accuracy. -uv run --frozen --group training python finetune.py train \ - --data run-output/lora-expanded-inputs --output run-output/my-lora2581 \ - --variants lora --recipe original --seed 89 \ - --validation-metric auc --export-dtype float32 --device "$ROUTER_DEVICE" -uv run --frozen --group training python finetune.py evaluate \ - --evaluation evidence/test.json --questions evidence/questions.json \ - --output run-output/my-lora2581 --device "$ROUTER_DEVICE" -``` +## 3. Adapt Laya with LoRA [answer cost savings PENDING; quality gap PENDING] -The recorded NVIDIA H100 run with seed 89 scored **66.60%**. Across all three seeds, mean accuracy rose -from 57.34% to 65.00%: **17.9% fewer errors**. The estimated improvement has a -95% uncertainty interval of **+3.20 to +12.04 percentage points**, calculated -by repeatedly resampling the test problems. Eight passes through more data -also means more training updates, so this improvement combines more examples -with more training work. The [training guide](docs/lora-study.md) includes the -full study and commands to inspect the recorded comparison on CPU. +**NVIDIA CUDA GPU for training; CPU for replaying the resulting table.** +LoRA trains small added weight updates while keeping most of Laya fixed. +We also train its final decision layers. Both correctness questions share one +model. Separate training papers select how long to train. -## 4. Train an embedding classifier on 64 examples [67.64%] +```sh +# Create your own training folders without changing the downloaded reference results. +uv run --frozen --group outcomes python router.py prepare \ + --study evidence --output run-output/my-router +``` -**CPU.** Change the design. **Qwen3-Embedding-4B** converts each problem into -2,560 numbers without changing the model's weights. Train a **ridge classifier**: -a weighted sum of those numbers, with a penalty that discourages overly large -weights and helps limit overfitting. It learns just 2,561 values, including a -constant offset.

Train the embedding router [net savings PENDING; quality gap PENDING] -**CPU.** Measure the test accuracy of the routing rules saved in step 4: +**CPU with the supplied embeddings.** Qwen3-Embedding-4B turns each question +into a list of 2,560 numbers describing its text. Two small **logistic +classifiers** learn from those numbers: one predicts whether Qwen 4B will be +correct, and the other predicts whether Qwen 27B will be correct. + +The routing score is the predicted quality improvement divided by expected +extra cost. Cost estimates come from training records; they never use a new +question's future answer length or correctness. ```sh -# Evaluate the saved classifiers on the separate test set and print their scores. -uv run --frozen python run.py evaluate +# Fit and evaluate both training sizes on CPU using the saved Qwen embeddings. +for population in original expanded; do + uv run --frozen --group outcomes python router.py fit-embedding \ + --study evidence --run run-output/my-router --population "$population" + uv run --frozen --group outcomes python router.py evaluate \ + --study evidence --run run-output/my-router --population "$population" \ + --method embedding --output "run-output/embedding-$population.json" +done ``` -Compare `ridge64` (**67.64%**) with `ridge512` (**72.03%**). The embedding model -stays fixed; only the small classifier changes. Both use one embedding call and -the same number of classifier weights per new request. The measured gain is -4.38 percentage points, but its uncertainty interval includes zero: this test -does not establish that the extra examples reliably improve accuracy. All -training sizes are retained in [results](docs/results.md).

Keep their answers, +correctness grades, token usage and SIE charge receipts. A router then selects +which of these two answers the user would have received. Every router shares +the same recordings, so differences come from routing decisions rather than +another random generation or another round of charges. + +- **Answer accuracy** is the fraction of correct final mathematical answers. +- **Quality gap** is always-strong accuracy minus routed accuracy, in percentage + points. We also count lost correct answers and answers rescued by the smaller + model. A negative gap is possible: the stronger model is not always right. +- **Answer-model cost** is the charge for the selected answer, including its + final-answer turn when one was needed. +- **Total serving cost** adds the routing decision. Always-strong and + always-cheap bypass the router and have no routing charge. +- **Savings** compare that cost with always-strong. When a router's hosting + cost is unknown, the report gives answer-model savings and the maximum + router cost that would still leave a saving; it does not assume free hosting. + +For example, 90% answer accuracy at $10 per 1,000 requests versus 88% at $4 +means a **2-point quality gap and 60% savings**. These numbers illustrate the +calculation; they are not benchmark results. + +The Cloud embedding measurement uses **one request at a time within each API +call**, even when several calls run concurrently. The 479 test embeddings cost +597 credits: **$0.00597 total, or $0.01246 per 1,000 requests** at the recorded +$0.00001 per credit. Both embedding classifiers have the same routing overhead. +Batching multiple problems into one call has different billing rounding and is +not used as a substitute for this measurement. + +## Select the routing rule before testing it + +We report two comparisons: + +1. **Original difficulty rules.** Keep each router's previously chosen cutoff. + This tests whether improving its difficulty accuracy also improves the + delivered answers and cost. +2. **Rules chosen for cost and answer quality.** Use the 246 calibration + problems to choose the cheapest cutoff within a declared quality-loss + budget. The primary budget is 1 percentage point; 0, 2 and 5 are reported + as additional choices. A cutoff determines which scores send a problem + to the stronger model. Always-strong is available when no cheaper rule + satisfies the calibration target. + +The selected rules and their input hashes are saved before collecting the +479 test answer pairs. Test reporting applies every saved rule. It does not +pick the best-looking test result or change the cutoff to hit the target. +A calibration target is an empirical check, not a promise about new requests. + +The comparison uses the recorded seed-89 versions of the router recipes in the +walkthrough. Difficulty-training tables also show averages over three seeds; those +averages do not describe a single deployed router. All 479 problems remain in +the evaluation. They are separate from training, but have been exposed in the +earlier router experiments; a new generalization claim needs new problems. + +## Check the answers + +Answer keys are joined from the pinned Easy2Hard source using exact problem IDs, +text and file hashes. They stay separate from the inference inputs. Models see +the problem and competition name; no reference answer, solution or difficulty +rating is sent to them. + +The grader extracts the explicit final answer and uses pinned **Math-Verify +0.9.0** to compare equivalent mathematical expressions. It does not search a +long solution for any expression that happens to match. It grades the final +value, not proof completeness or prose quality. + +Before grading the calibration or test answers, 28 answer conventions were +reviewed against the original problems and solutions, without consulting solver +outputs. These include ordered coordinates, sets, ratios and clock notation. +Seven questions explicitly ask for a percentage and accept the requested value +with or without a percent sign. Elsewhere, `42%` means `0.42`, not `42`. +Two source transcription errors were corrected: +`e2h-amc-eval-1694` to `1010000`, and `e2h-amc-eval-620` to `21000`. +The review retains every problem and records the corrections explicitly. + +`solver.py prepare` downloads and verifies the original source, separates +inference inputs from the answer key, and applies these checked review rules +automatically. It writes `gold-review.json` and +`gold-adjudication-details.json`; unresolved answers prevent collection. + +## Try two fresh Cloud answer pairs + +**CPU client; SIE Cloud generates the answers.** Create an account and API key +in the [SIE Console](https://console.superlinked.com).

For each answer model, we +calculate its mean token cost when correct and when wrong, then weight those +two means by its predicted correctness. A new request does not reveal its +future answer length or correctness to the router. A one-credit denominator +floor keeps the score defined when the estimated cost difference is very small. + +## The decision-model approach + +Laya has roughly 421 million parameters. It combines a ModernBERT-large text +encoder with a decision head: layers that score supplied choices instead of +generating an answer. We ask two questions about the same problem, one for +each answer model, with the choices `incorrect` and `correct`. Both questions +use one shared Laya checkpoint. + +The unchanged baseline uses the published weights. Training examples supply +its cost estimates, and calibration supplies its routing cutoff. Its predicted +probabilities should not be assumed to be perfectly calibrated. + +LoRA adds rank-16 updates to the attention layers while most encoder weights +stay fixed. We also train the complete decision head. Training uses the two +correctness labels and cross-entropy, which penalizes confident wrong +predictions. One held-out training-paper fold selects the number of epochs +from zero through eight; an epoch is a pass through the training examples. +The selection criterion is the summed negative log likelihood of both labels. +Ties prefer the earlier epoch. + +We then start again from the original checkpoint and fit all eligible training +questions for the selected number of epochs. The seed is 89. The original and +expanded populations use the same recipe. Training runs on NVIDIA CUDA; no +Apple-specific training result is substituted into this comparison. + +LoRA updates are merged into ordinary model weights. We save those weights at +32-bit precision and check scores before merging, after merging, and after +reloading. This catches export changes that could otherwise look like a +training-quality difference. + +## The embedding approach + +The fixed **Qwen3-Embedding-4B** model converts each request into 2,560 numbers. +Two independent logistic classifiers predict the two correctness labels from +those numbers. Each classifier has 2,560 weights and a bias; there are no +hidden layers and Qwen's weights are not updated. + +Five training-paper folds select a shared regularization strength from +`0.01`, `0.1`, `1`, and `10`. Regularization discourages large classifier +weights. Selection minimizes the combined negative log likelihood on the +held-out folds; ties prefer stronger regularization. Both classifiers are then +fitted to all training examples. The saved vectors make this fitting step +possible on CPU. + +The encoder, text instruction, and vector normalization stay fixed for both +training sizes and both label sources. A new request normally needs one +embedding call and two small CPU calculations. More training examples do not +increase the number of embedding calls or classifier parameters. + +The encoder is roughly ten times larger than Laya. This is a comparison of +practical recipes, with different model sizes and pretraining. It does not +isolate which architectural difference causes a quality difference. + +## When reference labels are unavailable + +The teacher comparison uses **gpt-6-astra** to solve each training problem from +the question alone. It does not receive the benchmark answer or either smaller +model's answer. Its final answer becomes the proposed reference for the two +correctness labels. + +Generic formatting checks determine whether a teacher reference can be used. +For example, an unsupported answer form or an unresolved unit is recorded as +unusable. Eligibility depends on the teacher reference itself, not on whether +it agrees with the benchmark or makes either answer model look good. There is +no fallback from a teacher label to the benchmark label. + +The matched reference-label control uses exactly the same eligible questions, +vectors, paper folds, and training settings. Only the label source changes. +Each version derives its cost estimates under its own labels. Calibration and +test use the reviewed benchmark references for both versions, so teacher +agreement is not mistaken for independently measured answer quality. + +The public commands reuse recorded labels. Acquiring new labels is a separate +one-time expense. A different teacher or a self-hosted 27B model is a new +label-source experiment, not an established equivalent to this teacher. + +## Choose a cutoff before seeing test outcomes + +Calibration chooses the cheapest routing cutoff whose observed quality gap is +within the declared target. The primary target is **one percentage point**; +zero-, two-, and five-point targets are also reported. Always using the stronger +model and always using the smaller model are explicit alternatives. Those +fixed choices skip the router's inference call. + +Every model and cutoff is saved before the held-out answer outcomes are opened. +The answer recordings were collected earlier; access to their outcomes is the +relevant boundary. The published receipts document that sequence. Once the +results are public, rerunning the example is a reproduction on a known test +set. Further development needs a fresh test for new generalization claims. + +## Translate the result into money and quality + +**Quality gap** is always-strong accuracy minus routed accuracy, in percentage +points. A change from 90% to 89% is a one-point gap: ten fewer correct answers +per 1,000 requests. We report both lost correct answers and rescues where the +smaller model succeeds while the stronger model fails. Losing five and rescuing +two produces a net loss of three. + +**Answer-model savings** compare the selected answer charges with the +always-strong charges. **Savings after known router charges** also subtract +embedding API charges. Dollar tables show costs and savings per 10,000 +requests, scaled from this measured sample. They are workload estimates, not +a quote for an arbitrary production workload. + +Laya hosting has not been priced as a production service. For a threshold +policy, its answer-model savings therefore provide a **hosting allowance**: +the maximum extra router spend before those savings disappear. They are not +net savings. Training and teacher labeling are separate one-time expenses. +Embedding-router results include its measured API overhead, while the small +local classifier calculation remains unpriced. + +The main test uses measured SIE Cloud charges, including a conditional +final-answer formatting call when needed. Training answers were collected +through self-hosted SIE servers; their cost model uses actual token counts and +recorded Cloud list prices. Those estimates are neither Cloud bills nor Modal +GPU charges. Runtime and model revisions are recorded, but matching weights +does not guarantee identical responses across serving environments. + +## Uncertainty and transfer to new questions + +A one-point calibration target is not a promise of at most one point of loss +on future requests. The main test has 463 questions. Paired bootstrap intervals +resample those questions with the routing policy fixed. They describe this +sample's uncertainty but do not account for shared papers, model selection, +solver randomness, or changing prices. One training seed does not establish +stability across seeds. + +A separate 2,000-question arithmetic check applies the same saved routers and +cutoffs without retraining.

The +[methodology](methodology.md) explains the labels, cost estimates and evaluation. -The terminal settings `SIE_BASE_URL` and `SIE_API_KEY` select the server and -authenticate requests. Use `https://api.superlinked.com` with your account key -for Cloud, or a local address such as `http://127.0.0.1:8098` for your own -server. Some SDK examples leave the URL unset because Cloud is the default; -this walkthrough sets it explicitly so a previous local setting cannot change -the destination. `unset SIE_API_KEY` clears the key from that terminal session; -it does not delete or revoke your account's key. +## What runs for each request -## What each design costs to serve - -| | Adapted Laya | Qwen embeddings + ridge classifier | +| | Unchanged Laya or Laya with LoRA | Qwen embeddings + two classifiers | | --- | --- | --- | -| Large model needed for every new request | About 421 million weights | About 4.02 billion weights | -| Small client-side calculation | Compare the model's option score with a cutoff | Normalize 2,560 numbers, apply 2,561 learned values and a cutoff | -| Model weight storage at 32-bit precision | About 1.57 GiB | About 14.98 GiB | -| Retraining | GPU required for LoRA and decision-layer updates | CPU works when embeddings are already available | -| Deployment in this example | Your own SIE server with your trained weights | Hosted Qwen on SIE Cloud, or your own SIE server; classifier stays local | - -The memory row counts **weights only**, not peak memory: both servers also need -space for intermediate calculations and runtime overhead. A GiB is about -1.07 billion bytes. Downloaded Qwen weights use 16-bit numbers and total about -8 GB; the example's portable local profile uses 32-bit computation on Apple -Silicon. Changing the precision is a separate deployment choice that should be -checked for accuracy. - -Qwen is about **9.55 times larger** than Laya. It also has different architecture -and pretraining. This experiment compares useful systems; it does not isolate -which of those differences causes Qwen's higher accuracy. The tiny classifier -is cheap, but computing a fresh embedding still requires the large model. Using -more training examples does not enlarge the ridge classifier or add embedding -calls to a new request. - -## Measure request latency - -We measured both approaches on the same Apple M3 Max with 128 GiB memory, -macOS 26.2, SIE server 0.10.0 and 32-bit model computation. Each server ran -separately. A persistent SDK client sent 20 warmup requests, then the same -32 test problems one at a time. The server's default adaptive batching was -enabled; warmup allowed its initial timing calibration to complete. - -| Time from SDK call to routing decision | Laya + expanded LoRA, seed 89 | Qwen4B + ridge512 | -| --- | ---: | ---: | -| Median | 48.77 ms | 171.51 ms | -| 95th percentile | 63.43 ms | 246.43 ms | -| Median local scoring work | 0.0015 ms | 0.87 ms | -| Decisions matching the frozen reference | 32/32 | 32/32 | - -The **median** is the middle response time. The **95th percentile** describes -the slower end of this small sample; it is not a service guarantee. These times -include local HTTP, server processing, response decoding and the final decision. -For embeddings, local scoring includes normalization, verifying the saved -classifier and computing its score. Downloads, model loading, process startup -and initial model checks are excluded. This measures neither concurrent -throughput nor Cloud network latency, and does not repeat the 479-problem -accuracy evaluation. - -The [recorded requests, environment, server logs and source files](https://huggingface.co/datasets/superlinked/sie-task-evidence/tree/12c2865c71dfc94bc9c28ff368134a8fefaced56/evaluations/2026-10-19/train-a-router-serving) -are published at a fixed revision with a file-hash manifest. All 17 files were -downloaded and verified without an account after publication. - -To measure your own Laya model, first train and evaluate it, then start its -server using [the main walkthrough](../README.md#serve-your-router). In another -terminal in this example directory: +| Main router model | About 421 million parameters | About 4 billion parameters | +| Work before choosing an answer model | Two correctness questions through one shared Laya checkpoint | One embedding call, then two small CPU calculations | +| What is learned | LoRA updates and the decision head; unchanged Laya keeps its published weights | Two logistic classifiers, each with 2,560 weights and a bias; the encoder stays fixed | +| Live routing | Local Python inference on CPU or NVIDIA CUDA | SIE Cloud or a self-hosted encoder; classifiers run locally on CPU | +| Training requirement | NVIDIA CUDA GPU for LoRA; a rented GPU such as Modal works | CPU when the saved embeddings are available | + +Both approaches estimate the correctness of each answer model and its expected +cost. The saved cutoff selects the model to call. If calibration selected an +explicit always-strong or always-cheap policy, live routing skips the decision +model or embedding call entirely. + +LoRA updates are merged into the exported Laya weights, so serving does not +require a separate adapter step. More training examples do not increase either +router's parameter count or number of model calls. Qwen is roughly ten times +larger than Laya and has different architecture and pretraining. A quality +difference between these recipes does not establish which difference caused it. + +## Use SIE Cloud from your computer + +Run these commands from `examples/train-a-router` after the README has created +`evidence` and trained `run-output/my-router`. The embedding route needs no +local GPU. Create an API key in the [SIE Console](https://console.superlinked.com) +and use your account's available credits.

The recorded +answer collection used SGLang 0.5.10.post1 with CUDA 12 for the 4B model and +SGLang 0.5.20 with CUDA 13 for the 27B model. The encoder used SGLang's embedding +runtime. Those environments need isolation. The existing PyTorch embedding +profile in `configs/` has not been checked for numerical equivalence with the +recorded SGLang vectors. Hardware, precision and runtime changes can affect +outputs even with identical weights. + +The public [SIE Helm deployment](../../../deploy/helm/sie-cluster/README.md) +supports a gateway with separate GPU worker groups for these runtimes. It is +the supported advanced deployment path. This example does not yet have a +tested compact launcher for all three models, or a tested three-model Helm +overlay. Do not assume one default server process can reproduce their distinct +runtime configurations. The recorded prompts, token limits and conditional +final-answer protocol are defined in [solver.py](../solver.py). + +## Measure warm inference separately from startup + +The single-question CLI verifies the selected checkpoint and loads Laya anew +on each invocation. Its saved `local_model_load_and_score_seconds` includes +model loading; `local_router_end_to_end_seconds` also includes metadata and +checkpoint checks.

Startup and checkpoint download time belong in a +separate measurement. + +The current Cloud probe used the same 20 hash-ordered training inputs as the +native timing probe, one separate warmup, and one request at a time. Embedding +plus classification took **184 ms median** and **274 ms at the 95th percentile**. +The local scoring portion took **0.21 ms median**. The SDK ran on an Apple +Silicon laptop; all embedding-model computation ran in SIE Cloud. Network time +is included. No answer model was called by this probe. + +The 20 timed calls used **23 credits**, or **$0.00023**. That scales to about +**$0.115 per 10,000 embedding calls for this small sample**. The main quality +report uses its own measured embedding charges, collected in batches of 16; +the timing probe does not replace those charges. ```sh -# Route a problem through the local full-fine-tuned comparison model. -export SIE_BASE_URL=http://127.0.0.1:8099 -unset SIE_API_KEY # The local server needs no Cloud key. -uv run --frozen python decision.py route --run evidence/native/seed-89 \ - --variant full --contest AMC10 \ - --request 'A rectangle has perimeter 30 and length 9.

Repeat with -`--variant lora` and another output file. Both checks matched 32/32 in the -recorded Apple Silicon verification. This checks serving consistency; it does -not make the native model more accurate than the embedding classifier. +Use the same SIE connection variables as the live-answer commands. This probe +makes 21 embedding calls, so it uses API credits. For an existing self-hosted +endpoint, add `--self-hosted` and set its URL and key. A policy that always +chooses one answer model would skip this work in deployment. + +Native inference measurements are still pending. Cloud timings and direct +Laya timings on a known GPU describe different serving setups; they are not a +controlled comparison of equal hardware. The example's live CLI does not +implement a persistent Laya service. This small sequential probe also does +not measure concurrent throughput. + +## Compare savings after serving costs + +The reports express dollars per **10,000 requests** alongside the answer-quality +gap from always using the stronger model. The main evaluation uses observed +Cloud answer charges, including conditional final-answer calls. Embedding +routes also include their observed encoder API charges; the small local CPU +calculation remains unpriced. + +For Laya, production hosting cost is still unpriced. Its answer-model savings +are a **hosting allowance**: the maximum additional router spend before those +savings disappear. For example, saving $20 in answer charges per 10,000 requests +leaves at most $20 to run the router before breaking even. That is an +illustration, not a measured result. Idle GPU time and utilization matter when +turning this allowance into a deployment budget. A static policy that skips +the router has zero router inference cost. + +Training and teacher labeling are separate one-time costs. Self-hosted GPU +charges also differ from the Cloud token-price estimates used for training +cost prediction and the arithmetic transfer study. Keep these acquisition +expenses, ongoing hosting expenses and per-request API charges separate when +deciding whether a router saves money on your workload. diff --git a/examples/train-a-router/evidence.py b/examples/train-a-router/evidence.py index 26a405351..bf6200443 100644 --- a/examples/train-a-router/evidence.py +++ b/examples/train-a-router/evidence.py @@ -16,6 +16,9 @@ LORA_REVISION = "d884d137386ccc4c89eb6d78449197a4e4be9892" LORA_MANIFEST_SHA256 = "f9f2f521de0dc6bc1711e7695378702efc03a55f017d29b7e52dc6552ae5872f" LORA_FOLDER = "evaluations/2026-10-18/train-a-router-lora-followup" +SOLVER_REVISION = "PENDING_PUBLICATION" +SOLVER_MANIFEST_SHA256 = "PENDING_PUBLICATION" +SOLVER_FOLDER = "evaluations/2026-10-19/train-a-router-answer-quality" BASE_URL = "https://huggingface.co/datasets/superlinked/sie-task-evidence/resolve/" @@ -45,12 +48,20 @@ def verify(directory, *, manifest_sha256=None): return files -def fetch(directory, weights=None, *, lora_study=False): +def fetch(directory, weights=None, *, lora_study=False, solver_study=False, solver_records=False, solver_weights=False): + if solver_study and (lora_study or weights): + raise ValueError("Choose one study; solver evidence contains no router weights") + if solver_records and not solver_study: + raise ValueError("--solver-records requires --solver-study") + if solver_weights and not solver_study: + raise ValueError("--solver-weights requires --solver-study") if lora_study and weights not in (None, "lora"): raise ValueError("The LoRA follow-up supports only --weights lora") revision = LORA_REVISION if lora_study else REVISION folder = LORA_FOLDER if lora_study else FOLDER manifest_sha256 = LORA_MANIFEST_SHA256 if lora_study else MANIFEST_SHA256 + if solver_study: + revision, folder, manifest_sha256 = SOLVER_REVISION, SOLVER_FOLDER, SOLVER_MANIFEST_SHA256 if "PENDING_PUBLICATION" in (revision, manifest_sha256): raise RuntimeError("Public evidence has not been pinned yet") destination = directory / "manifest.json" @@ -58,10 +69,14 @@ def fetch(directory, weights=None, *, lora_study=False): raise ValueError("Destination contains a different experiment") base = f"{BASE_URL}{revision}/{folder}/" with urllib.request.urlopen(base + "manifest.json", timeout=60) as response: - body = response.read(200_001) + body = response.read(2_000_001 if solver_study else 200_001) files = entries(body, manifest_sha256=manifest_sha256) directory.mkdir(parents=True, exist_ok=True) groups = {"core"} + if solver_records: + groups.add("answers") + if solver_weights: + groups.add("native-weights") if weights: groups.update(f"seed89-{v}" for v in (("full", "lora") if weights == "both" else (weights,))) for name, expected in files.items(): diff --git a/examples/train-a-router/generalization_data.py b/examples/train-a-router/generalization_data.py new file mode 100644 index 000000000..0e7fbe09c --- /dev/null +++ b/examples/train-a-router/generalization_data.py @@ -0,0 +1,164 @@ +"""Prepare an arithmetic transfer test without using any router outcomes. + +The competition test contains only 479 clean questions.

Its validation hardware uses three H100 80 GB GPUs, +one per model. That full inference setup is larger than the single GPU needed +for LoRA training.

This example does not establish -teacher-only labeling accuracy. - -## The two solver systems - -| Setting | Smaller solver | Stronger solver | -| --- | --- | --- | -| Model | `Qwen/Qwen3.5-4B` | `Qwen/Qwen3.8-27B-FP8` | -| Initial output limit | 1,536 tokens | 3,072 tokens | -| Requested working length | At most 150 words | At most 300 words | -| Temperature | 0 | 0 | - -Both receive the problem and competition name, without a reference answer, -solution or difficulty rating. If the initial response is truncated or lacks -an explicit final answer, the same solver gets at most one additional -256-token final-answer call. Both calls count toward serving cost. Automatic -inference retries are disabled. Exact prompts, model revisions and grading -rules are saved in the evidence and checked by the code. - -The recorded training pairs use self-hosted SIE; calibration and test pairs use -SIE Cloud. They share the declared model revisions and request settings, while -hardware, serving versions and scheduling differ. Runtime receipts preserve -those differences; identical deployment bytes are not claimed. Every compared -router selects from the **same recorded test answer pairs**, so reporting -does not generate another answer or incur another solver charge. - -## Download the experiment once — CPU - -Start at the repository root. Python 3.12 and `uv` are required. Fitting the -embedding router and replaying reports need only CPU. Native Laya training -needs an Apple Silicon GPU or an NVIDIA GPU, on your computer or a VM. Training -Laya on a Mac does not also host the two large answer models. - -```sh -# Install the example and download the pinned labels, vectors, plans and reports. -cd examples/train-a-router -uv sync --frozen --group evaluation -uv run --frozen python run.py fetch --solver-study -``` - -The default destination is `run-output/solver-study`.

It excludes -native weights and raw response archives.

They copy its historical plan bytes rather -than create a new assertion that you have never seen the test outcomes. -Every new stage receipt and evaluation is marked -`public_regression_reproduction`. A new generalization claim requires a fresh -test split; repeatedly improving this published score is not that test. - -### Prepare a new reproduction — CPU - -```sh -# Copy the historical plans into a new run without fitting either router yet. -uv run --frozen python benefit_replay.py prepare --output run-output/my-benefit -``` - -The command prepares both model families. Neither has been fitted, and no -Cloud call or model download is needed. - -### Train native Laya — Apple or NVIDIA GPU - -Select **one** device. On NVIDIA, use `cuda`; on Apple Silicon, use `mps`. -The [Mac guide](mac-training.md#runtime-settings) explains the Apple GPU -memory settings. Its historical timings are not timing estimates for this -different training objective. - -```sh -# Install native training dependencies and select your NVIDIA GPU. -uv sync --frozen --group training --group evaluation -export ROUTER_DEVICE=cuda -``` - -```sh -# On Apple Silicon, replace the device selection with the Apple GPU. -export ROUTER_DEVICE=mps -``` - -```sh -# Train and export the native benefit router using the same recorded labels. -uv run --frozen --group training python benefit_replay.py fit-native \ - --run run-output/my-benefit --device "$ROUTER_DEVICE" -``` - -The command downloads the pinned public Laya checkpoint if needed. It records -unchanged Laya and trains rank-16 attention adapters plus the decision head. -Targets −1, 0 and +1 become strong-option training weights 0, 0.5 and 1. -A training-only paper fold selects among the initial model and eight epochs; -the selected epoch count is then fitted from a fresh base on all 511 examples. -The initial model is eligible to win. Calibration chooses the cutoff afterward. - -Merged checkpoints are exported as ordinary 32-bit Laya weights and checked -for changes in scores. Outputs are under `my-benefit/native/base/` and `lora/`. -Allow several GB of disk space per run. Hardware can change numerical results -and the selected epoch; the guide does not promise identical GPU training bytes. - -### Fit the embedding router — CPU - -```sh -# Fit a small regression model and the competition-name control from cached vectors. -uv run --frozen python benefit_replay.py fit-embedding --run run-output/my-benefit -``` - -Qwen3-Embedding-4B stays fixed. The command learns 2,560 feature weights and a -bias from the saved vectors and signed-benefit labels. Paper-grouped training -folds choose the regularization strength; calibration then chooses cutoffs. -It also fits the fixed competition-name control. No embedding or solver API -calls are needed. Outputs are under `my-benefit/head/` and `my-benefit/control/`. -This CPU fit and native training are independent; evaluation needs both. - -### Evaluate your frozen models — CPU - -```sh -# Apply every saved cutoff to the published paired answers and print the comparison. -uv run --frozen python benefit_replay.py evaluate --run run-output/my-benefit -``` - -The command writes `my-benefit/evaluation.json` and `evaluation.md`. It reports -always-strong, always-cheap and all four router variants. The primary cutoff -targets at most **1 percentage point of quality loss on calibration**; 0, 2 -and 5 are retained as additional choices. These are empirical calibration -targets, not guarantees for test data or future requests. Reporting never -selects a different cutoff from the test table. - -Existing outputs are not overwritten. If a stage fails, preserve its records -and use a new reproduction directory for another complete attempt. No -`authorize-test` command is needed or appropriate for this public replay. - -## Answer a new question through SIE Cloud - -Create an API key in the [SIE Console](https://console.superlinked.com), then -set the endpoint explicitly. The regression model stays on your computer; -SIE Cloud supplies embeddings and the selected answer model. - -```sh -# Select SIE Cloud and authenticate with your own account key. -export SIE_BASE_URL=https://api.superlinked.com -export SIE_API_KEY='paste-your-key' -``` - -```sh -# Use your fitted embedding router to choose one solver and save its answer and charges. -uv run --frozen python benefit_route.py --run run-output/my-benefit/head \ - --contest AMC10 --question 'A rectangle has perimeter 30 and length 9.

Each invocation needs a new output -directory and makes a new paid answer request; the two commands above are two -requests. The route uses at most one embedding or native decision, one solver -answer and one conditional final-answer turn. A static always-strong/cheap -calibration choice bypasses the routing model. `result.json` records the -selected model, answer and available API charges. A new question without a -reference answer is **not automatically graded**. - -To try published native weights without training them, download the optional -checkpoints and use the published head/native pair together: - -```sh -# Download the native checkpoints and use the published LoRA router on local CPU. -uv run --frozen python run.py fetch --solver-study --solver-weights -uv run --frozen --group training python benefit_route.py \ - --run run-output/solver-study/benefit/head \ - --native-run run-output/solver-study/benefit/native --variant lora --device cpu \ - --contest AMC10 --question 'A rectangle has perimeter 30 and length 9. What is its area?' \ - --target 1 --output run-output/published-benefit-answer -``` - -CPU scoring is supported here; native **training** still requires a GPU. -Use a matching head/native plan pair. These commands select both from the -published study. - -## Use your own answer-model deployment - -An existing SIE deployment must expose both pinned answer-model IDs above and -support the structured final-answer call. The embedding route also needs -`Qwen/Qwen3-Embedding-4B` at its pinned revision on that endpoint; the local -native route does not.

Training uses supervised cross-entropy, AdamW with cosine learning-rate -decay, and shuffled choice-option order with aligned targets.

The [source review](laya-adaptation.md) -explains the motivation and differences from public Laya adaptation recipes. - -Selection has three separate steps: - -1. Train each of the six recipes on 512 examples for seeds **89, 137, and 211**. - For each run, choose the maximum ROC AUC on the 2018 validation set. Epoch zero - is eligible; ties retain the earliest epoch. Cross-entropy and training loss - remain diagnostics. -2. Choose the recipe with the highest mean selected validation AUC across all - three seeds. Ties retain recipe declaration order, shown in the table. Write - `recipe-frozen.json` before starting the larger training runs. -3. Train that same recipe on 2,581 examples for all three seeds, with unchanged - learning settings. For every selected checkpoint, fit its cutoff by balanced - accuracy on the separate 2019 calibration set. Calibration does not choose the - recipe or epoch. Write `all-frozen.json` when every run is complete. - -The 18 screening runs plus three expanded runs are all retained. No best seed -is selected. The driver checks that both training directories have identical -validation, calibration, and question files, and that the smaller training file -is the exact prefix of the expanded one. It never reads test inputs. - -Keeping eight epochs also increases the training budget: 512 examples produce -256 optimizer updates, while 2,581 produce 1,296. This compares the practical -recipe of adding examples and training for the same number of passes; it does -not isolate dataset size at fixed compute. - -## Why this study exports FP32 weights - -The original Laya serializer writes half-precision weights. In the first -LoRA-study attempt, that conversion changed validation logit margins beyond the -declared export tolerance. Before recipe selection or test evaluation, the -study was amended to preserve FP32 weights for every candidate. The initial -attempt is retained as an audit; the training recipes and data did not change. - -The study passes `--export-dtype float32` to `finetune.py`. This changes the -saved checkpoint precision, not the training objective or native architecture. -Encoder adapters are merged, validation margins are checked before and after -merge and export, and calibration uses the reloaded exported checkpoint. All -candidates in this study use the same export rule. The original baseline keeps its -original export and selection protocol. Consequently, the historical CE baseline -versus the new original-recipe AUC control changes both checkpoint selection and -export precision. That comparison cannot attribute a difference to selection -alone. Recipe and training-size comparisons within the new study all use FP32. - -## Evaluate only after the study is frozen - -Wait for `ALL_LORA_RUNS_FROZEN` and `run-output/my-lora-study/all-frozen.json`. -Then make the original evidence available on the evaluation machine and run: - -```sh -# Check runtime parity, evaluate the frozen study, and recompute its report. -uv run --frozen --group training python lora_evaluate.py \ - --study run-output/my-lora-study --evidence evidence \ - --device "$ROUTER_DEVICE" --timeout-seconds 1800 -uv run --frozen python lora_report.py \ - --study run-output/my-lora-study --evidence evidence \ - --output run-output/my-lora-report.json -``` - -The evaluator checks the completed study and development selections, then sets -`TORCH_COMPILE_DISABLE=1` and `TORCHDYNAMO_DISABLE=1` before loading any model. -Each frozen checkpoint must reproduce its selected validation scores and saved -calibration scores within a maximum absolute margin difference of **0.03**, with -**zero changed decisions** at its existing cutoff on both splits. These checks -run in isolated processes under the same overall timeout. The declared checks, -per-checkpoint scores, and completion hashes are saved in `runtime-parity` -receipts. A failed check stops the run before test inputs are opened. - -In the recorded run, all six checkpoints passed: maximum development-margin -drift was 0.000174, with no changed decisions. The first evaluation attempt had -produced a plan but no outcome files during a prolonged startup. That plan and -the runtime amendment are retained in the public audit. The startup cause was -not localized; disabling compilation did not eliminate the initial delay. - -After every checkpoint passes, it evaluates the original recipe at 512 examples, the -selected recipe at 512, and the selected recipe at 2,581, each for all three -seeds. If the original recipe wins, its 512-example stage is evaluated once. -Existing parity and evaluation outputs are preserved; rerunning an interrupted -attempt in place is refused. The runtime change keeps weights and cutoffs fixed; -latency measurements from eager and compiled execution are different comparisons. -Fresh GPU evaluation needs the -trained weights; downloading only the published core records supports CPU report -replay instead. - -The report compares these stages with the original CE-selected native runs and -the unchanged `ridge512` embedding reference. The published test is an **exposed -regression benchmark** in this study. Development selection is separate from -its outcomes, but a new claim about future generalization requires a new test -population.

It combines a ModernBERT-large text -encoder with a decision head: layers that score supplied choices instead of -generating an answer. We ask two questions about the same problem, one for -each answer model, with the choices `incorrect` and `correct`. Both questions -use one shared Laya checkpoint. - -The unchanged baseline uses the published weights. Training examples supply -its cost estimates, and calibration supplies its routing cutoff. Its predicted -probabilities should not be assumed to be perfectly calibrated. - -LoRA adds rank-16 updates to the attention layers while most encoder weights -stay fixed. We also train the complete decision head. Training uses the two -correctness labels and cross-entropy, which penalizes confident wrong -predictions. One held-out training-paper fold selects the number of epochs -from zero through eight; an epoch is a pass through the training examples. -The selection criterion is the summed negative log likelihood of both labels. -Ties prefer the earlier epoch. - -We then start again from the original checkpoint and fit all eligible training -questions for the selected number of epochs.

Training runs on NVIDIA CUDA; no -Apple-specific training result is substituted into this comparison. - -LoRA updates are merged into ordinary model weights. We save those weights at -32-bit precision and check scores before merging, after merging, and after -reloading. This catches export changes that could otherwise look like a -training-quality difference. - -## The embedding approach - -The fixed **Qwen3-Embedding-4B** model converts each request into 2,560 numbers. -Two independent logistic classifiers predict the two correctness labels from -those numbers. Each classifier has 2,560 weights and a bias; there are no -hidden layers and Qwen's weights are not updated. - -Five training-paper folds select a shared regularization strength from -`0.01`, `0.1`, `1`, and `10`. Regularization discourages large classifier -weights. Selection minimizes the combined negative log likelihood on the -held-out folds; ties prefer stronger regularization. Both classifiers are then -fitted to all training examples. The saved vectors make this fitting step -possible on CPU. - -The encoder, text instruction, and vector normalization stay fixed for both -training sizes and both label sources. A new request normally needs one -embedding call and two small CPU calculations. More training examples do not -increase the number of embedding calls or classifier parameters. - -The encoder is roughly ten times larger than Laya. This is a comparison of -practical recipes, with different model sizes and pretraining. It does not -isolate which architectural difference causes a quality difference. - -## When reference labels are unavailable - -The teacher comparison uses **gpt-6-astra** to solve each training problem from -the question alone. It does not receive the benchmark answer or either smaller -model's answer. Its final answer becomes the proposed reference for the two -correctness labels. - -Generic formatting checks determine whether a teacher reference can be used. -For example, an unsupported answer form or an unresolved unit is recorded as -unusable. Eligibility depends on the teacher reference itself, not on whether -it agrees with the benchmark or makes either answer model look good. There is -no fallback from a teacher label to the benchmark label. - -The matched reference-label control uses exactly the same eligible questions, -vectors, paper folds, and training settings. Only the label source changes. -Each version derives its cost estimates under its own labels. Calibration and -test use the reviewed benchmark references for both versions, so teacher -agreement is not mistaken for independently measured answer quality. - -The public commands reuse recorded labels. Acquiring new labels is a separate -one-time expense. A different teacher or a self-hosted 27B model is a new -label-source experiment, not an established equivalent to this teacher. - -## Choose a cutoff before seeing test outcomes - -Calibration chooses the cheapest routing cutoff whose observed quality gap is -within the declared target. The primary target is **one percentage point**; -zero-, two-, and five-point targets are also reported. Always using the stronger -model and always using the smaller model are explicit alternatives. Those -fixed choices skip the router's inference call. - -Every model and cutoff is saved before the held-out answer outcomes are opened. -The answer recordings were collected earlier; access to their outcomes is the -relevant boundary. The published receipts document that sequence. Once the -results are public, rerunning the example is a reproduction on a known test -set. Further development needs a fresh test for new generalization claims. - -## Translate the result into money and quality +The denominator has a floor of one credit.

The final classifiers are refit on all training rows. + +The decision-model approach uses one shared **Laya** checkpoint, based on +ModernBERT-large, and asks it the same two correctness questions. The unchanged +checkpoint is the baseline. Adaptation trains rank-16 attention LoRA updates +and the complete decision head. The recipe uses seed 89, adapter learning rate +0.0002, head learning rate 0.0001, dropout 0.05, and weight decay 0.01. + +We check epochs 0 through 8 on one reserved training-family fold. **Epoch 0** +means no adaptation. The epoch with the lowest combined prediction loss is +selected, with earlier epochs winning ties. We then restart from the original +checkpoint and train on all rows for that many epochs. Calibration and test +outcomes never select the training duration. Both arithmetic training sizes +selected one epoch. Adapter merging and checkpoint export are checked for +score drift before use. + +For each training size, a matched unchanged-Laya control uses the same +training-derived cost estimates as its adapted counterpart. Its weights stay +fixed, and calibration chooses its own cutoff. This separates changing the +weights from updating the expected answer costs. The controls were saved in a +separate, hash-checked supplement before opening test answers; they do not +replace or modify the original frozen comparison. + +This comparison does not establish that LoRA generally beats full fine-tuning, +or that a model's parameter count alone explains its performance. + +## Choose a cutoff, then open the test results + +The primary target is an empirical **one-percentage-point quality gap on +calibration**. We choose the lowest-cost qualifying cutoff, also considering +always-cheap and always-strong policies. Secondary targets of 0, 2, and 5 +points are declared in advance and retained in the report. + +The source plan aimed for at least 30% savings near a one-point quality gap. +The primary 2,000-example embedding rule saves 20.87% with a 0.47-point test +gap, so it does not reach that savings aim. The declared two-point calibration +setting saves 33.77% with a 0.83-point test gap; its gap interval extends to +1.30 points. We report that as a secondary operating point, without changing +the primary comparison or claiming a guaranteed one-point bound. + +All model files, input-only test scores, and calibration cutoffs are saved +before test answers are graded. A test result can exceed its calibration +target: the target is not a guarantee. The public download contains the frozen +decisions and test-access record. Replaying these published results is an +**exposed reproduction**, not another blind experiment. + +The report keeps additional controls: models trained on competition problems +with their original cutoffs, and those same weights with arithmetic-only +cutoff calibration. These distinguish adjusting the cutoff from training +weights on the new workload. Their original training-derived cost means stay +fixed. They are diagnostic comparisons, not extra stages learners must run. + +Separate experiments used only the 2,000 exposed development questions. An +answer-aware cascade, which inspects the cheaper model's answer before deciding +whether to upgrade, was screened with training-fold validation. Two fixed +changes to the cheaper solver's generation settings were also tested on all +2,000 questions. Neither solver change met the improvement rule specified +before collecting those answers.

The routing commands use the same prompts, model revisions and +conditional final-answer calls as SIE Cloud. + +This is an optional inference deployment. The main example can use SIE Cloud +for these calls and needs only one GPU for LoRA training. + +You need **Linux, Docker Compose, NVIDIA Container Toolkit and three separate +NVIDIA GPUs**. The validation hardware is three H100 80 GB GPUs. The strong +model's pinned image requires a CUDA 13 compatible driver. This is a larger +deployment than the single GPU used to train Laya's LoRA adapter. Sharing one +GPU between all three workers has not been validated. + +The first start downloads about 48 GB of model weights, in addition to the +container images. The named `model-cache` volume retains those weights. +Each worker gets a separate runtime because the answer models need different +SGLang/CUDA versions. The answer workers use released images pinned by digest. +The encoder builds the `sglang-embedding` bundle from an exact public SIE +commit: the released generation bundle does not accept embedding adapters. +This initial CPU image build also takes time. The image digests, build commit +and model revisions are pinned in [compose.yaml](compose.yaml) and [models/](models/). + +Run these commands from `examples/train-a-router`: + +```sh +# Check the Compose configuration and start all workers, waiting for model readiness. +docker compose -f self-host/compose.yaml config --quiet +docker compose -f self-host/compose.yaml up --build --detach --wait --wait-timeout 1200 +``` + +The default device IDs are 0, 1 and 2. Set `CHEAP_GPU`, `STRONG_GPU` and +`ENCODER_GPU` before startup to choose different, distinct devices. Cold model +loading takes several minutes. Inspect startup with +`docker compose -f self-host/compose.yaml logs --tail 100` if readiness fails. +The health checks require each pinned model profile to be loaded; a running +HTTP process alone does not count as ready. The SDK smoke below additionally +checks real inference and the structured final-answer path. + +```sh +# Install the client dependencies and check metadata, embeddings and both answer protocols. +uv sync --frozen --group outcomes +export SIE_BASE_URL=http://127.0.0.1:8080 +export SIE_API_KEY='' +uv run --frozen --group outcomes python self-host/smoke.py \ + --output run-output/self-host-smoke +``` + +The smoke check makes one embedding request and an initial answer plus a +forced structured finalizer for each answer model. The cheap worker preloads +both its speculative and grammar-safe engines, reserving 40% of GPU memory +for each. This avoids loading a second engine during an answer. Token admission +is capped at 8,192 per profile; this recipe is for sequential requests. +It validates immutable model revisions and saves an incomplete receipt +if any step fails. Use a new output directory for another attempt. + +After following the main example's training instructions: + +```sh +# Route a new request with your saved classifiers, then call only the selected answer model. +uv run --frozen --group outcomes python router.py answer \ + --study evidence --run run-output/my-router --population expanded \ + --method embedding \ + --question 'A rectangle has perimeter 30 and length 9. What is its area?' \ + --target 1 --self-hosted --output run-output/self-hosted-answer +``` + +`--self-hosted` allows missing Cloud billing receipts; GPU hosting is still +unpriced. It preserves model identity checks. The saved calibration target is +not a guarantee for an individual answer or a new workload. + +```sh +# Stop the workers and proxy while preserving the downloaded model cache. +docker compose -f self-host/compose.yaml down +``` + +The frontend listens only on `127.0.0.1:8080`; worker ports 18081–18083 are also +published only on loopback. SGLang child ports stay on the private Compose +network. This is a trusted local deployment with no API-key authentication. +Docker administrators and other local users are privileged peers. Do not +publish these ports on a network without designing and reviewing authentication. + +The small proxy accepts only the three pinned model metadata paths, the +encoder path and chat completion requests for the two answer models. It bounds +request bodies and headers, rejects ambiguous JSON model fields and strips +client credentials before forwarding. There are no automatic request retries. + +The GPU smoke passed with both exact released answer images and the pinned +encoder build: all three model revisions, embeddings, both initial/finalizer +pairs, and one public routed request. Application processes ran as UID 1000 +with writable caches and the original image dependencies. Modal connected the +isolated workers through authenticated tunnels and required materializing the +encoder Dockerfile's final `FROM` build argument to its intended stage; the +public Compose build uses the original Dockerfile and ordinary build arguments. +A complete Docker Compose GPU stack has not been executed as one deployment. +These checks do not establish throughput or bit-for-bit
