Hugging Face adds an RL Environments filter to the Hub, supporting 4 frameworks
lmoroney · x · 2026-10-06
Hugging Face now offers an RL Environments filter on the Hub: environments are dataset repos tagged rl-environment with framework tags for Harbor, Verifiers, OpenEnv, and NeMo Gym, and the "Use this dataset" button gives you the run command—no new repo type or registry. The author recommends starting with the Harbor example, which runs a task's reference solution through the verifier without calling a model, making reward debugging much easier.
