What it does
OpenRLHF helps teams improve large language models with reinforcement learning from human feedback (RLHF), which rewards a model for answers people prefer. It can also train multi-step AI agents and models that understand images.
It spreads the work across many graphics cards, and its makers say it handles models of 70 billion parameters and more.
Who it's for
AI researchers and engineers training large language models.
