Thanks, but I didn't find any details about performance of pre reinforcement training and after. Looking to understand more about the assertion that hallucinations are introduced by the reinforcement training.

The technical report has before and after comparisons. It's a bit worse on some tests. and they pretty explicitly mention the issue of calibration (how well confidence on a problem results in the ability or accuracy solving that problem).
also, this paper on gpt-4 performance of medical challenge problems confirmed the high calibration for medicine https://arxiv.org/abs/2303.13375
