Fei-Fei Li's team launches Atlas: agents build coarse 3D, model renders pixels

Ben Mildenhall announces the Atlas release: purely procedural pixel generation via code remains orders of magnitude costlier than direct generation, so the two approaches are complementary. Atlas ships a Chisel web app plus Codex/Claude Code integrations where an agent builds coarse 3D geometry while Atlas endpoints control precise final pixels. A finetuned Chisel variant accepts any mix of partial RGB and depth frames—masked depth renders of a car plus text prompts control both style and scene infill.
