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!

A critical look at the experimental predictions of the Integrated Information Theory (IIT) of consciousness
In a previous post, I discussed Anil Seth’s paper on biological naturalism. Together with my colleague Rif A. Saurous, we also had an in-depth look at Integrated Information Theory (IIT), the topic of...

Finally, a bold move!
There are two main problems with the current state of things.
1. There are no disincentives to flooding conferences with submissions.
2. Zero accountability towards reviewers who do a bad job.
This could solve both with one simple change. Great initiative @ijcai.org 👏👍

I can't stop thinking about this article. For the record, I am still impressed when undergrads get a single paper before grad school... 😅

Gemini 3’s new Deep Think mode tackles problems by exploring multiple hypotheses at once ⚡
Positioned as Google’s most advanced reasoning tier, Deep Think runs iterative rounds to refine outputs—especially for complex tasks like code visualization, prototyping, and nuanced analysis.

Spotify is garbage on every count: Its treatment of artists, its ICE advertising, the CEO's investment in military AI, its leading role in the commodification and AI slopification of music, its terrible audio quality—you name it.

I spent most of my time at AAMAS this year telling everyone I met that the future of general MARL is "predictive agents" that are inherently Bayesian. So I am happy to see this paper!
1/ Why does RL struggle with social dilemmas? How can we ensure that AI learns to cooperate rather than compete?
Introducing our new framework: MUPI (Embedded Universal Predictive Intelligence) which provides a theoretical basis for new cooperative solutions in RL.
