Awesome work by my friend @PimDeWitte and the people at @gen_intuition
Introducing MIRA.
A playable, multiplayer world model.
A dream of Rocket League.
Trained on 10k hours of data collected with publicly available bots, MIRA learns the dynamics of a four-player game. The model runs in real time at 20 fps, based on the keys you and the other y General Intuition and @kyutai_labs, in collaboration with Epic Games. Not used to develop Rocket League.
▶️ Play the demo, read the technical report, and explore the open-source code at generalintuition.com/mira
At ICML? Find us at Booth 111 to try it yourself and dig into the results with the team.

Beautiful and intuitive work by a good friend!
With UMA playground, the crazy things Feynman could only ask us to imagine become something you can see. Heat, break, and build at aidemos.atmeta.com/uma

Lot of dystopian AI discussion on here as usual. Much is out of my control on that front, but I did use AI to build nice map of (imo) best 80,000 books of all time: bookscape.site

Dataset is a combination of Goodreads and Project Gutenberg. Goodreads dataset I found had too much self help and romance, and actually lacked some classics

In the near future I'm going to keep building my own projects on top of it and tweaking it here and there. A lot of this is a learning experience wrt what is needed from infrastructure in the age of semi- and fully-autonomous AI agents

Takeaways: 1) really specific error messages in the API and dev server + a self-documenting API endpoint are essential 2) it's good to give the agent intermediary goals when building more complex sites 3) I think serious, scalable applications will be built this way someday

I have long wished that information - from movies, to books, to music, to websites, to really anything - were spatially organized.
The usefulness of Memory Palaces / Method of Loci suggest that this would help us. Perhaps an antidote to infinite scrolling?

This is a small step in that direction. But someday I hope the whole internet will be one enormous UMAP we can fly over.

More on this soon. Pretty much works but want to build more projects on top of it to work out the bugs
@karpathy Yes! I built a humble attempt at solving this issue:
- minimalist dev server for building with Claude Code
- API for deployment, DNS setup, etc
- Stripe + email + database + storage + etc
- Self-documenting API (curl tidepool.sh/api)
See tidepool.sh/quickstart

This screenshots show interesting islands - a WWE island, a southeast asian cinema continent (bollywood, etc), Scooby-Doo, Peter Pan (+Hook etc)
The individual movies have different genres, cast, etc and yet since they share plot, characters & themes the UMAP puts them together
