4/N The first tournament? Chess, with top models like Gemini 2.5 Pro, o3, and DeepSeek-R1. Matches will be covered by Magnus Carlsen, Hikaru Nakamura, and Levy Rozman (GothamChess)

3/N
3. Resistance to benchmark saturation—many games remain unsolved by brute force or memorization
4. Strong emphasis on high-level behaviors: planning, reasoning, memory, adaptation, even deception

2/N By using head-to-head board game matchups, it offers several advantages over many existing evaluations:
1. Direct comparisons across a range of strategic games
2. Streamed, replayable matches that improve transparency and reproducibility

1/N I’ve long believed that board games should play a bigger role in AI evaluation. They naturally test strategic reasoning, long-term planning, adaptation—and they can’t be solved by brute force or memorization.

Game Arena is transparent, replayable, and tests actual behavioral intelligence.

A year after our trip to AAMAS in New Zealand, @sharky6000.bsky.social came back for more!

I should have planned my year not to miss @aamasconf.bsky.social…

Big congrats and keep up amazing work! 🎉👏

ML Pub Club #22: Superhuman Planning with LLMs · Luma What happens when a chess champion meets cutting-edge AI? Join us for an evening with Matej Jusup, as he unpacks how large language models (LLMs) can go from…

Looking forward to speaking at the ML Pub Club on June 3rd!

I'll discuss how, during my time at DeepMind, we taught LLMs to play chess at a GM level and the broader implications for strategic AI.

If you're in Zagreb, join us at Mažuranićev trg 13 at 6 PM!

Mastering Board Games by External and Internal Planning with Language Models Advancing planning and reasoning capabilities of Large Language Models (LLMs) is one of the key prerequisites towards unlocking their potential for performing reliably in complex and impactful domains...

A paper from my time at Google was accepted for a spotlight presentation at ICML!

In “Mastering Board Games by External and Internal Planning with Language Models”, we show how language models can achieve grandmaster-level play using a search budget on par with humans.

Sim agents are key for developing autonomous systems for safety-critical systems, like self-driving cars.

We're open-sourcing sim agents that achieve a 99.8% success rate with < 0.8% failures on the Waymo Dataset. These agents are built through scaling self-play.

Robust Autonomy Emerges from Self-Play Self-play has powered breakthroughs in two-player and multi-player games. Here we show that self-play is a surprisingly effective strategy in another domain. We show that robust and naturalistic drivi...

I've been talking about writing this paper to anyone who would listen since 2020. I bombed a bunch of job talks trying to convince companies to work on this. It's so nice to finally just be able to say, yes, self-play RL in a diverse world gives you immense capabilities

Pet peeve: Calling something that’s not open source… open source. Open weight != open source

Graphics fill of statistics on the efficiency or in efficiency of cars

Graphics fill of statistics on the efficiency or in efficiency of cars

A typical European car is parked 92% of the time. It spends 1/5th of its driving time looking for parking. Its 5 seats only move 1.5 people. 86% of its fuel never reaches the wheels, and most of the energy that does, moves the car, not the people.

Sound efficient?

29th BOŠNJACI Open • Round 1 9-round Swiss | 90 min + 30 sec / move | standard | Bošnjaci, Croatia | Saric, Culum, Pap, Zaja

The first round was a hard-fought win against a much lower-rated opponent, but it is a testament to the increased playing quality since the recent global chess boom!
