Small step for a finger on "post tweet" button. Big step for millions of future AI agents doing useful work for us.

Hear me out. Universe is 13B years old. Human intelligence took about 4B years to evolve on earth, which needed an earlier supernova explosion to generate heavier elements. We may be the earliest intelligent life in the galaxy.

Why am I excited about IMO results we just published: - we did very little IMO-specific work, we just keep training general models - all natural language proofs - no evaluation harness We needed a new research breakthrough and @alexwei_ and team delivered

We trained a model and it is good in some things

We're releasing a preview of OpenAI o1—a new series of AI models designed to spend more time thinking before they respond. These models can reason through complex tasks and solve harder problems than previous models in science, coding, and math. openai.com/index/introduc…

To summarize this week: - we released general purpose computer using agent - got beaten by a single human in atcoder heuristics competition - solved 5/6 new IMO problems with natural language proofs All of those are based on the same single reinforcement learning system

I don't do podcasts very often - in reality this is my first one ever, but if anyone wants to listen to someone talk about RL for an hour, this is it

Science of RL optimization is likely humanity’s last open scientific problem

Intelligence is so much about pattern matching that it’s actually hard to say what else is there

i’m much more inclined to say that the RL *system* inside OpenAI is AGI rather than than any fixed model checkpoint which comes out of it

At OpenAI regularly you hear a lot of complaints about how bad things are, and it’s one of the things that make us the highest functioning company in the world. A bit of Eastern European culture that became part of the company DNA

In short 49th to 98th percentile of performance in IOI in one year without training any specialised models. Same RL as for everything else we do

1/n I’m thrilled to share that our @OpenAI reasoning system scored high enough to achieve gold 🥇🥇 in one of the world’s top programming competitions - the 2025 International Olympiad in Informatics (IOI) - placing first among AI participants! 👨‍💻👨‍💻
