And he finally got it #Messi𓃵

woooo go Ishaan Singal - so proud of your work on this!

What can an 8-year-old build in 45 minutes with the assistance of AI? My daughter has been learning to code with Cursor and it's mind-blowing🤯 Here are highlights from her second coding session. In 45 minutes she built a chatbot powered by Cloudflare Developers Workers AI 👀

o1-preview and o1-mini are here. they're by far our best models at reasoning, and we believe they will unlock wholly new use cases in the api. if you had a product idea that was just a little too early, and the models were just not quite smart enough -- try again.

Say ho ho ho to Santa in Voice Mode 🎅 Santa is rolling out today to everyone across all ChatGPT platforms and is available until the end of the month…then he will retire back to the North Pole.

"are you not entertained"?

Introducing the Responses API: the new primitive of the OpenAI API. It is the culmination of 2 years of learnings designing the OpenAI API, and the foundation of our next chapter of building agents. 🧵Here’s the story of how we designed it:

GPT-4.1 (and -mini and -nano) are now available in the API! these models are great at coding, instruction following, and long context (1 million tokens). benchmarks are strong, but we focused on real-world utility, and developers seem very happy. GPT-4.1 family is API-only.

This one is for the developers!

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).

turns out you can always just work harder

GPT-5.1 is out! It's a nice upgrade. I particularly like the improvements in instruction following, and the adaptive thinking. The intelligence and style improvements are good too.

It's potentially the most competitive last 30 days in AI Coding history. GPT-5.2 represents the biggest leap for GPT models in agentic coding since GPT-5 and is a SOTA coding model in its price range. The version bump undersells the jump in intelligence. We’re excited to make

its not all about the benchmarks

Sometimes all you can do is keep your heads down and ship valuable things. So so proud of the team(s) that worked on GPT-5.4. The wide reception is blowing us all away and more than makes up for all the sleepless nights. DMs open for any feedback!
