What a 'world model' is — and what Decart's Oasis 3 does
AI that builds explorable, video-game-like worlds — and why it's a big deal for robots and cars.
Decart's Oasis 3 (10 June 2026) is an AI that generates realistic, interactive driving scenes.
You've heard of AI that writes text or makes images. A 'world model' does something different — and Decart's Oasis 3 is a good way to understand it. Here's the plain-English version.
What it's for
Self-driving cars need to practise dangerous, rare situations — a child running into the road, ice, a sudden lane change — but you can't safely create those over and over in real life. With Oasis 3, engineers can type a description and instantly generate that scene, in different weather and road conditions, as many times as they like, to train and test the car's AI.
Why it matters
This kind of realistic simulation could speed up self-driving cars and robots — the broad field people call 'physical AI', where AI controls things in the real world, not just on a screen. Decart even wants other developers to build their own tools on top of Oasis 3, the way apps are built on other AI services.
