A month after launching GPT-5.1, OpenAI is rolling out the GPT-5.2 series (Instant, Thinking, and Pro), which it calls its most advanced solution for professional work. The tool’s creators emphasize it’s moving beyond simple chat to tackle complex, multi-step tasks. The new models are designed to deliver real economic value—from building advanced spreadsheets and writing code to precise analysis of images and long texts.
Expert-level performance
In the GDPval tests, which cover tasks typical of 44 different occupations (representing key sectors of the U.S. economy), the GPT-5.2 Thinking variant matched or outperformed human experts in 70.9% of cases. For comparison, the previous version (GPT-5) hit that mark in only 38.8% of trials.
