DAPO: An Open-Source LLM Reinforcement Learning System at Scale

New open-source way to teach big language models to reason — DAPO

Researchers just released a simple and powerful system that helps big language models think more clearly, and they made it open-source.
The method, called DAPO, trains models by giving them feedback, so the model learns to pick better answers over time, and it works at large scale.
You can try it, study it, or build on it because the code and cleaned data are public, not locked behind walls like before, which feels like a small revolution for people who tinker and learn.

The team focused on making the whole process repeatable, so others can copy the work and test ideas, improving reproducibility across the field.
This relies on reinforcement learning ideas but without the confusing parts — it's about rewards, practice, and using more compute to get smarter results.
The result is a clear path for hobbyists and labs to explore better reasoning in AI, and yes, the tools are ready to use, so experiments can start right away, or anytime you want to play with smarter models.
