Hugging Face describes a TRL update that sends only weight deltas, instead of full model checkpoints, during async RL training. The approach stores sparse safetensors diffs in a Hugging Face Bucket and lets vLLM fetch them, cutting per-step transfer size dramatically and enabling disaggregated training across separate machines and Spaces.
