ARC Prize

Google DeepMind's Gemini 4 Argon scored 97.5% on ARC-AGI-3 at a cost of $4,800 using the Provider Adapter Harness, according to ARC Prize. Under the Standard Harness it falls to 49.8%, and Epoch AI places it eighth on its Math ECI and sixth on its SWE ECI.

Claude Opus 5 scored 30.2 percent on the ARC-AGI-3 benchmark, nearly four times the previous record of 7.8 percent set by OpenAI's GPT-5.6 Sol (Max). The ARC Prize team attributes the leap to genuinely stronger reasoning, though an independent test on a separate puzzle benchmark showed far smaller improvements.
