+Runpod also keeps a few standby workers parked for each endpoint so jobs can start quickly with [FlashBoot](/serverless/endpoints/endpoint-configurations#flashboot). The API shows their target count as `workersStandby`, and the [`/health` operation](/serverless/endpoints/operation-reference#health) can list them as ready. Runpod picks this number for you, and you aren't billed for a parked worker until it starts running.
+`workers=(0, N)` still scales to zero.
