Massive World Model Release & AI Agent Action! Marble & Google's SIMA 2!

Two Game Changers in Gen AI! Today I've got a hands-on deep dive into World Labs’ Marble (Gaussian-splat virtual sets you can edit, expand, and animate—now widely available with new features and surprising pricing) and a breakdown of Google Deepmind's SimA-2 research—an agent learning inside generated worlds via Genie 3 and guided by Gemini. I show how I used Marble to build a virtual set for my short “Alarm,” demo multi-image world bashing, keyframed camera moves, video export/enhance, canvas/node edits, and practical limits. Then we unpack SimA-2 vs SimA-1, success rates, consistency/hallucination issues, and why spatial intelligence matters for the future of AI video, games, and robotics.
