LLMs Mastering Board Games: ZurichNLP Meetup - Feb 20th!

Excited to share insights from my student research at Google DeepMind at the upcoming ZurichNLP meetup! I'll present how we achieved high-level play in board games using LLMs with a search budget comparable to human chess grandmasters.

After 15 years away from competitive chess, I forgot how much thrill and excitement the game gives! ♟️ I decided to attend a tournament with five grandmasters and numerous international, fide, and candidate masters.

I was honored to present our demo on “Mastering Chess With Language Models” at the @GoogleDeepMind booth at @NeurIPSConf right before an inspiring talk by Jeff Dean

Thanks to everyone who dropped by and made it a memorable session! ♟️

I couldn’t ask for a better @neuripsconf.bsky.social
welcome! Spotted a lovely family playing chess and had the joy of facing a brilliant 6-year-old who just learned the game 3 days ago. Her enthusiasm was truly inspiring!

Amazingly, the model can learn to perform internal search within a single LLM call, allowing for smooth scaling of playing strength with the number of tokens! 🤯

An efficient external MCTS reaches grandmaster-level strength with a search budget comparable to that of human players! 🔥

A single LLM can learn to play multiple board games—including Chess, Chess960, Hex, and Connect Four—at a master level! 💪
