GPT-4o (o for “omni”) is the first model to come out of the omni team, OpenAI’s first natively fully multimodal model. This launch was a huge org-wide effort, but I’d like to give a shout out to a few of my awesome team members who made this magical model even possible!
Congrats to the GDM team on their IMO result! I think their parallel success highlights how fast AI progress is. Their approach was a bit different than ours, but I think that shows there are many research directions for further progress. Some thoughts on our model and results 🧵
1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
Today, we at @OpenAI achieved a milestone that many considered years away: gold medal-level performance on the 2025 IMO with a general reasoning LLM—under the same time limits as humans, without tools. As remarkable as that sounds, it’s even more significant than the headline 🧵

Watching the model solve these IMO problems and achieve gold-level performance was magical. A few thoughts 🧵
