Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

TRL's AsyncGRPOTrainer now supports LoRA training, shipped in v1.14 via PR #7017. The setup runs training and inference on separate machines, syncing only the multi-megabyte LoRA adapter to vLLM workers rather than the full ~3GB policy, cutting communication overhead for async GRPO RL training.

Concrete architecture from the HF team, with PR reference and bandwidth numbers, for separating RL training and inference across machines via adapter-only sync.
