According to ARC Prize (@arcprize) and Greg Brockman (@gdb), GPT-5.2 Pro has set a new state-of-the-art (SOTA) benchmark on ARC-AGI, scoring 90.5% with a dramatic 390X efficiency improvement compared to last year’s models (source: ARC Prize, Greg Brockman, 2025). In 2024, an early version of OpenAI o3 (High) achieved 88% accuracy at an estimated $4,500 per task, while the new GPT-5.2 Pro (X-High) delivers higher accuracy at only $11.64 per task. This leap in both accuracy and cost-efficiency signals a major advance for enterprise AI adoption, enabling more scalable, cost-effective deployment of advanced reasoning AI models for industries including education, healthcare, and enterprise automation (source: ARC Prize, 2025).
