Marble

Marble is the first commercial product from World Labs, the spatial-intelligence lab co-founded by Stanford's Fei-Fei Li. Launched in limited beta in November 2025 and commercially in early 2026, it generates persistent 3D scenes from a text prompt, image, video clip or 360° panorama — worlds you can walk through and edit, not flat video. The killer feature for production work is export: scenes come out as Gaussian splats or meshes you can drop into a game engine or VFX pipeline. Pricing runs free through $20/$35/$95 monthly tiers, with a developer API on top. World Labs raised $1B in February 2026, and AMD reportedly moved to acquire the company for around $8.2B in late September 2026.

The honest picture: generated worlds are plausible, not measured — World Labs' own docs say Marble infers geometry rather than reconstructing it, so don't expect survey-grade accuracy. Commercial usage rights only kick in at the Pro tier, API rate limits are tight by default (around 3 generations a minute), and the AMD acquisition, if it closes, could reshape pricing and availability. It's a world builder for previs, games and simulation, not a replacement for photogrammetry.
