GPT-5.2 Pro vs Nemotron-4 15B

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

GPT-5.2 Pro is clearly ahead on the aggregate, 90 to 47. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5.2 Pro's sharpest advantage is in coding, where it averages 84.8 against 26.5. The single biggest benchmark swing on the page is LiveCodeBench, 81 to 22.

GPT-5.2 Pro is the reasoning model in the pair, while Nemotron-4 15B is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-5.2 Pro gives you the larger context window at 400K, compared with 32K for Nemotron-4 15B.

Quick Verdict

Pick GPT-5.2 Pro if you want the stronger benchmark profile. Nemotron-4 15B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
