Hugging Face researchers surveyed 16 open-source libraries implementing async RL training patterns, comparing them across seven design axes, and distill lessons for building async trainers.

## Evidence

Verbatim from https://huggingface.co/blog/async-rl-training-landscape:

> We surveyed 16 open-source libraries that implement this pattern and compared them across 7 axes: orchestration primitives, buffer design, weight sync protocols, staleness management, partial rollout handling, LoRA support, and distributed training backends.
