Neither o3 nor o3-mini are widely available yet, but safety researchers can sign up for a preview for o3-mini starting today. An o3 preview will arrive sometime after; OpenAI didn’t specify when.

The o3 model scored 76% accuracy on ARC-AGI in an evaluation formally coordinated by OpenAI and the author of ARC-AGI, François Chollet, a scientist in Google's artificial intelligence unit.
