OpenAI on Thursday released its answer to Google’s impressive Gemini 3 Pro model–GPT-5.2—and by the looks of some head-to-head benchmark test scores, it looks like a winner. The new model took the highest score on a number of benchmark tests covering coding, math, science, tool use, and vision. (Benchmarks should, of course, be combined with real-world use to tell the whole story. But still . . .)

OpenAI says GPT-5.2, which is a reasoning model, achieved expert-level performance scores on its own GDPval benchmark, which evaluates performance on 44 real professional tasks including things like spreadsheet creation, document drafting, presentation building, and more.

GPT-5.2 topped Gemini 3 Pro on the SWE-Bench Pro benchmark (software engineering tasks) with a score of 55.6% (versus Gemini
