Refresh Deployed Model

Hot-swap the latest adapter checkpoint into an already-deployed model.

Calls the train GPU server to find the current adapter checkpoint step, then performs an undeploy + redeploy so the inference server loads the latest weights. The deployed model ID and inference URL remain unchanged.

Raises 400 if:

  • Model is not in DEPLOYED state
  • No adapter checkpoint is available yet (adapter_available == false)
  • Train-time alignment failed with a zeroth checkpoint (status == "failed" AND adapter_available == true)
