【[71星]lmpo：一个简洁易懂的语言模型策略优化GitHub项目。它通过强化学习对语言模型进行后训练，帮助提升模型在特定任务上的表现。亮点：1. 核心代码仅约400行，易于理解和修改；2. 支持多主机TPU训练，同时兼容单主机和GPU；3. 实现了多种经典LLM强化学习环境，如Countdown和GSM8K】

'lmpo: A minimal repo for Language Model Policy Optimization. This repo is a standalone implementation of using reinforcement learning to post-train language models. The focus is on ease-of-understanding for research. Please fork and/or play with the code! The lmpo repository is built using JAX, and has no major external dependencies. The core logic is around 400 lines of code, split into three files. This repo is in-progress, but decently clean.'
