deep learning is magic:.
Another one. Already a powerful painting, but moving around it yourself gives a totally different feeling. Jacques Louis David's "The Death of Socrates" => #Genie3

before my current gig, I was (among other things) chief of the chart crime police for the reasoning team at OAI. moderately proud how many people have texted me today saying I would never have let that plot happen lol 😅.
this screenshot from GPT-5 livestream has to be among the worst chart crimes of the century

The GDM proofs are lovely! Congrats to the team for an impressive effort.

fun: 3/4 months ago I ran o3 for some academics on a set of AIME-style problems. It has taken them so long to write a summary of the results (96% irrc) that Alex solved proof & IMO in the meantime lol.

17 M U.S. teens grades 9-12, ~5 US IMO golds in practice but ~20 kids at gold-level. So IMO gold is one-in-a-million math talent (for 18 year olds; but I bet next Putnam falls too). 99.9999th percentile.

If you claim to have seen this coming, you better have the manifold P&L to back it up

We are seeing much faster AI progress than **Paul Christiano** and **Yudkowsky** predicted, who had gold in 2025 at 8% and 16% respectively, by methods that are more general than expected.

RT @SherylHsu02: It’s crazy how we’ve gone from 12% on AIME (GPT 4o) → IMO gold in ~ 15 months. We have come very far very quickly. I woul….

nb this was tweeted 7 hours before OAI announced their gold result.
So, all the models underperform humans on the new International Mathematical Olympiad questions, and Grok-4 is especially bad on it, even with best-of-n selection? Unbelievable!

an incredible achievement; congratulations!.
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).

on the rare occasions that Jakub tweets, the wise listen.
I am extremely excited about the potential of chain-of-thought faithfulness & interpretability. It has significantly influenced the design of our reasoning models, starting with o1-preview. As AI systems spend more compute working e.g. on long term research problems, it is.
