CoreWeave Publishes RL Rollouts Docs: Hot-Loading Checkpoints Without Restarts
_ScottCondron · x · 2026-10-07
CoreWeave published official docs for RL Rollouts (preview), detailing how to serve RL rollouts and hot-load updated policy weights into running Dedicated Inference deployments.
- Supports full or delta checkpoints from CoreWeave AI Object Storage, loaded without restarting inference processes or recreating replicas.
- Hot-loading is enabled per organization and requires the dynamo-vllm engine (NVIDIA Dynamo + vLLM).
- The Dedicated Inference API is versioned v1alpha1 and may change before GA.
- Docs cover creating a hot-load-enabled deployment, generating rollouts, publishing checkpoints, and verifying all replicas serve new weights.
