According to Greg Brockman (@gdb), GPT-5.2 has exceeded the human baseline on the ARC-AGI-2 benchmark, demonstrating significant progress in artificial general intelligence evaluation (source: Greg Brockman, Twitter, Dec 23, 2025). This achievement signals a breakthrough in large language model capabilities, as ARC-AGI-2 is designed to rigorously test reasoning and generalization skills that are typically challenging for AI systems. Surpassing the human baseline on this benchmark suggests that GPT-5.2 can handle complex cognitive tasks at or above average human performance, opening new business opportunities in AI automation, advanced problem-solving, and knowledge work augmentation. This milestone is expected to accelerate the adoption of AI in sectors such as education, research, and enterprise productivity, where human-level reasoning is essential.
