Anthropic's Opus 5 scores 30.2% on ARC-AGI-3, nearly quadrupling previous record
Anthropic's Claude Opus 5 achieved a 30.2 percent score on the ARC-AGI-3 benchmark, nearly quadrupling the previous record of 7.8 percent set by GPT-5.6 Sol. According to the benchmark's developers, the model independently formulated reflection equations, a behavior not previously observed in other models and attributed to stronger logical reasoning.
Why it matters: This result suggests a significant leap in AI reasoning capabilities, potentially bringing models closer to more general intelligence.
