arc-agi-3

OpenAI's GPT-6 Astra rates first place on Epoch AI's aggregate benchmark but ties its predecessor on Artificial Analysis. Its human-beating move efficiency on ARC-AGI-3 led ARC Prize co-founder François Chollet to call progress 2x faster than expected.

The ARC Prize Foundation released ARC-AGI-3, an interactive benchmark requiring AI agents to explore environments, form hypotheses, and execute plans without instructions. All 135 environments were solved by untrained humans, yet frontier models—including Gemini 3.1 Pro Preview (0.37%), GPT 5.4 (0.26%), Opus 4.6 (0.25%), and Grok-4.20 (0.00%)—scored below 1%.
