Check Your Work: Why Self-Verification Deserves Its Own Training Budget
TL;DR for operators A post-training team deciding where to spend its next training budget should not infer verification ability from task accuracy. In Learning to Self-Verify Makes Language Models Better Reasoners, Chen et al. find that training models to solve mathematical problems better does not reliably make them better at judging whether solutions are correct.1 Training the reverse capability behaves differently: models trained only to judge their own generated solutions subsequently solve problems about as well as models trained directly for generation. ...
