About

GPT-5.2, released December 11, 2025, closed out OpenAI's 2025 with its strongest general model of the year: 92.4% on GPQA Diamond and 80.0% on SWE-Bench Verified, arriving less than a month after GPT-5.1 and directly answering Google's Gemini 3.0 Pro and Anthropic's Claude Opus 4.5 from the preceding weeks.

It also scored 52.9% on ARC-AGI-2, at the time among the best published results on the abstract-reasoning benchmark. GPT-5.2 anchored OpenAI's lineup through the winter while the coding-focused GPT-5.3-Codex branch shipped in February 2026, and was ultimately succeeded by GPT-5.4 in March 2026.
