GPT-5.2

GPT-5.2 is OpenAI's frontier model designed for professional knowledge work and long-running agents, with a three-tier intelligence system (Instant, Thinking, and Pro) that adapts response depth to query complexity. According to OpenAI's December 11, 2025 announcement, the model is better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex multi-step projects. This positioning makes it well-suited for enterprise workflows that require sustained reasoning, tool integration, and structured output across extended sessions.

On benchmarks, GPT-5.2 Thinking achieves 70.9% on GDPval wins or ties (knowledge work tasks across 44 occupations), up from 38.8% for GPT-5.1 Thinking, and reaches 55.6% on SWE-Bench Pro, 80.0% on SWE-bench Verified, 92.4% on GPQA Diamond, 100.0% on AIME 2025, and 86.2% on ARC-AGI-1 Verified. These results reflect meaningful gains in software engineering, scientific reasoning, and abstract problem-solving, supporting the model's fit for coding assistants, research workflows, and analytically demanding professional tasks where reliability and depth matter more than raw speed.
