Weekly AI: world models get physical, Devin Fusion cuts costs 9% with a pricier lead model
TheTuringPost · x · 2026-09-16
The Turing Post's weekly digest shows AI closing in on the physical world:
- alayastd built a world model that remembers what happens to objects even after they leave the frame
- Fei-Fei Li's World Labs launched Atlas, turning a few images into explorable 3D scenes — including views the camera never captured
- Cognition's Devin Fusion runs two models on the same coding task; surprisingly, using a more expensive model as the lead made sessions 9% cheaper thanks to better delegation
- Persimmon is making simulated users less conveniently helpful
- Dario Amodei wants AI development to slow down so safety can catch up; Goodfire is on board while David Sacks pushes back, asking who these rules actually protect
