Model profile / OpenAI
GPT-5.2 is a API model tracked via Artificial Analysis independent evaluations for capability comparison across coding, agents, and reasoning.
Four areas of evidence
Mathematical and scientific problem solving.
Score uses the admitted direct native evidence under the selected method.
Software engineering and programming.
Factual reliability and instruction following.
Score uses the admitted direct native evidence under the selected method.
Tool use, workflows and professional tasks.
Current index snapshot · 2026-09-16. Each category uses its own scale; scores across categories are not directly comparable. Evidence counts describe the retained Capabilities inputs; a family can contain several tasks or configurations. A point lead does not establish superiority.
Performance in context
GPT-5.2 is highlighted wherever a compatible measurement is available.
