Empirical AI · a world-models research lab
The map of world models, verified claim by claim.
World models — systems that learn how the world evolves and predict what happens next — are the most contested frontier in AI. This site is a living survey of the field (every claim checked against primary sources), a catalog of the models you can actually download, and the home of our own experiments.
The survey
12 sections from JEPA to driving — taxonomy, lineage, debates, open problems. 10 fully verified so far.
Open-weight models
12 verified downloadable world models — params, licenses, links. Cosmos 3 to Oasis 500M.
Our research
Prompt → 3D Gaussian-splat worlds on a single GPU, and evaluation work at small-lab scale.
