They did compare it to other models: https://x.com/OpenAI/status/1999182104362668275

This looks cherry-picked, for example Claude Opus had a higher score on SWE-Bench Verified so they conveniently left it out, also GDPval is literally a benchmark made by OpenAI

agreed.

And who believes that the difference between 91.9% and 92.4% is significant in these benchmarks? Clearly these have margins of error that are swept under the rug.

uh oh, where did SWE bench go :D

maybe they will release with gpt-5.2-codex

The fact that the post is comparing their reasoning model against gemini 3 pro (the "non reasoning" model) and not gemini 3 pro deep think (the reasoning one) is quite nasty. If you compare GPT5.2 thinking to gemini 3 pro deep think, the scores are quite similar (sometimes one is better sometimes the other one is)

The matrix required for a fair comparison is getting too complicated, since you have to compare chat/thinking/pro against an array of Anthropic and Google models.

But they publish all the same numbers, so you can make the full comparison yourself, if you want to.

They are taking a page out of Apple's book.

Apple only compares to themselves. They don't even acknowledge the existence of others.

OpenAI has never compared their models to models from other labs in their blog post. Open literally any past model launch post to see that.
