ARC-AGI-2

by ARC Prize

What is ARC-AGI-2? ARC-AGI-2 is a reasoning & knowledge eval made by ARC Prize. Grid puzzles where the solver sees a few input-output examples, infers the hidden rule and must draw the exact output grid, with two tries per test input. The repo has 1,000 public training tasks and 120 public evaluation tasks; people in the creators' test sample averaged 66% on the evaluation set, and two private sets are kept back to limit leakage.
