The model achieves 72% on the ARC-AGI benchmark (vs. 49% for GPT-4o), 88% on GPQA (doctorate-level science), and 90%+ on most professional certification exams. New features include extended thinking mode for complex reasoning, native tool use, improved instruction following, and significantly reduced hallucination rates on factual queries.
