Developer trains 12.5M-parameter world model on RTX 3080 Ti to play Pokémon Red

A developer known as stmonty built a small AI 'world model' that learns to play Pokémon Red by observing screen frames rather than being told game rules or win conditions. The model, with about 12.5 million parameters, was trained entirely on a single consumer RTX 3080 Ti GPU using over 42,000 grayscale frames from more than 1,000 short in-game runs. It draws on JEPA-style world model research co-authored by AI scientist Yann LeCun, who left Meta last year to pursue similar work at his new AMI Labs.

AMD to buy Fei-Fei Li's World Labs for $8.2 billion in all-stock deal

AMD announced an agreement to acquire World Labs, the San Francisco AI lab building 3D 'world models' founded by researcher Fei-Fei Li, in an all-stock deal valued at roughly $8.2 billion. Li will join AMD as chief scientist and executive vice president, while World Labs will operate separately from AMD's chip business until the deal closes later this year.

Runway launches Solaris, an AI model that renders interactive interfaces frame by frame

Runway introduced Solaris, which it calls an interface world model, letting users build interactive apps, websites and digital scenes by directly clicking and dragging on-screen elements instead of writing code. The system pairs a language model that determines how an interface should evolve with a rendering engine that generates each frame live, treating clicks and drags as signals to produce new visuals in real time. Runway demonstrated use cases such as virtually trying on clothes by dragging garments onto a photo of yourself, plus text-prompt edits like recoloring or repositioning objects.
