Outcome RL models show limited gains in reliability, study finds

A new paper by Yue et al. investigates the effectiveness of Outcome RL models in solving physics and math problems. The study found that while Outcome RL improves the ability to finish problems within a token budget (pass@1), it does not significantly enhance reliability for larger sets of problems (pass@k). The research suggests that much of the observed improvement is due to the model completing tasks before the budget expires, rather than acquiring fundamentally new knowledge or solving problems the base model could not.

IMPACT Findings suggest current RL models may not significantly advance problem-solving capabilities beyond existing methods, highlighting areas for future research in reliability and knowledge acquisition.
