Years in this space
I've evaluated a lot of these over the years. What stands out here is customizable prompts and reward functions — handled better than most — and compatible with Hugging Face models. Worth the time if this is your use case.
Compared a few options
Evaluated this against two competitors. Where it wins: gym-compatible environment support and reduces boilerplate for LLM RL training. Where it lags: training LLMs is compute intensive. On balance the feature set — especially customizable prompts and reward functions — justifies the 5 stars for our use case.
Solid for our team
We rolled this out across the team last quarter and familiar Gym-style environment interface. Lightweight, hackable Python codebase fits neatly into how we already work, and customizable prompts and reward functions removed a step we used to do by hand. but it has held up under daily use.
Does the job
Pretty happy overall. Hugging Face transformers integration just works and reduces boilerplate for LLM RL training. Training LLMs is compute intensive can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on customizable prompts and reward functions, and open source and free to use caught me off guard. Training LLMs is compute intensive is why this isn't a perfect score, still, I'd recommend giving it a real trial.
问答
What are the limitations of LlamaGym?
LlamaGym has limited documentation, requires significant compute resources for training LLMs, and has a smaller community compared to mainstream RL libraries.
