From RL Papers to Framework Code: Inclusion and Review in Seven Open-Source Training Frameworks

Practitioners use reinforcement learning methods for language models through training frameworks, so a method that a framework includes is one configuration change away for its users.

Key points

  • We trace seven open-source frameworks for RL post-training through their commit histories and link them to 6,939 screened arXiv papers from January 2025 to June 2026.
  • Of 1,598 papers that propose a general RL training method, 37 reached at least one framework.
  • Both gaps hold without papers from the companies that maintain the frameworks, while code release was equally common in both groups.
  • We release the data as a tracker that links training failures to framework implementations and lists each framework's contribution rules and earlier proposals.
