Open weights are not enough: we need open training frameworks for research and better algorithms [P]

In three linesFeynRL, an open-source framework for RL post-training of LLMs and agents, aims to make training transparent and modifiable. The author argues open weights alone are insufficient: explicit training codebases separating algorithms from systems are needed. Framework supports SFT, DPO, multi-GPU and cluster setups.
