OpenAI: GPT-5.2

OpenAI's GPT-5.2, released December 10, 2025, is a frontier-grade model designed for broad task coverage with a substantial 400,000 context length. It performs among the fastest models, ranking in the 73rd percentile for speed across benchmarks. However, it is positioned at premium pricing levels, falling into the 18th percentile for cost. A standout feature is its exceptional reliability, demonstrating a 100% success rate with minimal technical failures. GPT-5.2 exhibits remarkable accuracy in critical areas. It achieved perfect scores in Hallucinations (100%), General Knowledge (100%), and Ethics (100%), indicating strong factual grounding and ethical alignment. Its performance in Coding (96% accuracy) and Instruction Following (86% accuracy) is also very strong, showcasing its capabilities in complex technical and multi-step tasks. While its Mathematics accuracy (92%) is solid, its Reasoning (76%) and Email Classification (98%) scores, though respectable, are not as dominant as its top-tier performances. The model's adaptive reasoning allows it to efficiently handle varying task complexities, contributing to its consistent gains across diverse workloads and improved tool-use reliability.
