About
Halo is an open-source framework built by White Circle for post-training large language and multimodal models. It keeps models in their native HuggingFace format while claiming up to 2.8x the throughput of the standard TRL library with lower peak memory usage.
Why it made the leaderboard
Offers teams doing LLM post-training a faster, lower-memory alternative to stock TRL without changing their downstream HuggingFace-based tooling.
