We achieved gold medal level performance on this year's IMO! Our model thinks and writes proofs in clear, plain‑English - no formal code required. Unlike the narrower systems used in past competitions, our model is built to reason broadly, far beyond contest problems.

GPT-4o can now seamlessly generate images! imo it could be a big step toward intuitive AI interactions (Pictured: visual poetry + text rendering + photorealism) @OpenAI
4o image generation has arrived. It's beginning to roll out today in ChatGPT and Sora to all Plus, Pro, Team, and Free users.
4o image generation is finally out! @gabeeegoooh, @ajabri, @eliza_luth, @kenjihata, @jianfw, @dmed256 M have really made something magical, go try it out!!
this was a real labor of love from @gabeeegoooh. congrats gabe; excellent work! here is what we generated during the livestream:
