Only 37 of 1,598 arXiv RL training methods made it into open-source LLM training frameworks
Taiheng Pan · hf · 2026-10-22
- A tracker study across seven open-source LLM training frameworks (Jan 2025–Jun 2026) found 1,598 RL training methods on arXiv, but only 37 were adopted into framework code.
- Despite growing publication volume, adoption of academic RL methods remains low, highlighting a large gap between RL research and engineering practice in LLM training.
- The rl-method-tracker dashboard visualizes publication and adoption trends over time (see chart).
