The new model displays expert-level skill in work tasks, and exceeds Gemini in several benchmarks. 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 . . .)
