Hello all! 👋 🚨 New Preprint Alert! 🚨

Code World Models for General Game-Playing. ♟️🎲 ♣️♥️♠️♦️

I am pleased to announce our new paper, which provides an extremely sample-efficient way to create an agent that can perform well in multi-agent, partially-observed, symbolic environments!

🧵 1/N
Also, value functions will soon be cool again! 👍 thank you pistar_0.6 .. and Ilya thinks they will be used more in the future 🙏

What is the human analogy to pretraining? Learning up to the age of 15 where you have general knowledge but not economically productive? Or more like evolution, where it's a massive search over many years which produces a human lifetime instance?

Ilya: "Suppose you have two students doing competitive programming. Student 1 collects all the possible type of questions, studies for thousands of hours conquering them all. Student 2 studies much less, maybe 100 hours. Both perform comparatively. Which one goes on to have a better career?"

Ilya: "One thing you could do-- and I think this is done inadvertently-- is take inspiration from the evaluation." then goes on to imply that overfitting to evals could explain lack of generalization.

Why the heck am I hearing this for the first time in late 2025?

I've had this song on repeat for practically the whole weekend.

It brings me back to the good ol' days .. late 90's / early 2000s when I first go into EDM. I'd listen to this kind of stuff for hours.

Anybody see this song played live?

And I think it's a reference to.. 👇

Pluribus on Apple TV is such a great show - infuriatingly difficult to recommend though since it's so easy to spoil the experience if you share too many details

Just watch it, it's great!

Grand opening, grand closing.

X quietly disabled a new feature that showed which country an account was posting from when it revealed that lots of popular right wing MAGA accounts were being run from foreign countries like India and Nigeria.

The new Nano Banana Pro model (based on Gemini 3) is just incredible!!!

I always wanted to create a nice Gemma timeline for my presentations but I'm not that good with drawing tools

With just one prompt I managed to create something pretty cool!!

Clarification on recent AI doomer speculation.

I was confused by this recent move to invest big a few days ago given the article quoted below by Globe & Mail (Oct 7th, '25). 👇

It felt it was inconsistent with the portrayal of Buffet's opinion in October.
