GPT-6 Astra represents a step-function change in model capability for interactive reasoning problems. It scores 66% on ARC-AGI-3 using our standard harness, and nearly 100% with a continuous conversation harness and custom compaction, at a cost of roughly $360 per game.In fact,…— François Chollet (@fchollet) September 3, 2026
Introducing Index: Building The World’s Largest and Most Diverse Physical Dataset
Today we're coming out of stealth with the largest robot training dataset ever built. The data needed to scale general robotics doesn't exist on the internet - it has to come from the real world: a global sampling of physics captured across every environment on earth.
