Not to beat a dead horse or get into a debate, but to hopefully clarify the record:

- OpenAI denied training on FrontierMath, FrontierMath-derived data, or data targeting FrontierMath specifically

- The training data for o3 was frozen before OpenAI even downloaded FrontierMath

- The final o3 model was selected before OpenAI looked at o3's FrontierMath results

You can of course accuse OpenAI of lying or being fraudulent, and if that's how you feel there's probably not much I can say to change your mind. One piece of evidence against this is that the primary source linked above no longer works at OpenAI, and hasn't chosen to blow the whistle on the supposed fraud. I work at OpenAI myself, training reasoning models and running evals, and I can vouch that I have no knowledge or hint of any cheating; if I did, I'd probably quit on the spot and absolutely wouldn't be writing this comment.

Totally fine not to take every company's word at face value, but imo this would be a weird conspiracy for OpenAI, with very high costs on reputation and morale.
