GPT-5.5 and Opus 4.7 show systematic reasoning failures on ARC-AGI-3 benchmark

By PulseAugur Editorial · [3 sources] ·

A new benchmark, ARC-AGI-3, has revealed significant reasoning errors in advanced AI models like GPT-5.5 and Opus 4.7. These models achieved a mere 0.8% success rate on the benchmark, highlighting persistent gaps in abstract reasoning capabilities. The findings suggest that despite technological advancements, current AI systems struggle with fundamental human-level tasks. AI

IMPACT Reveals persistent reasoning gaps in frontier models, suggesting current architectures may not scale to human-level abstract thought.

RANK_REASON The cluster reports on a new benchmark evaluation of existing AI models, which falls under research.
