GPT-5 (high) vs Nemotron 3 Super 120B A12B

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

GPT-5 (high) is clearly ahead on the aggregate, 79 to 61. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5 (high)'s sharpest advantage is in multimodal & grounded, where it averages 89.4 against 60.4. The single biggest benchmark swing on the page is MMMU-Pro, 93 to 55.

GPT-5 (high) is the reasoning model in the pair, while Nemotron 3 Super 120B A12B 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. Nemotron 3 Super 120B A12B gives you the larger context window at 256K, compared with 128K for GPT-5 (high).

Quick Verdict

Pick GPT-5 (high) if you want the stronger benchmark profile. Nemotron 3 Super 120B A12B only becomes the better choice if you need the larger 256K context window or you would rather avoid the extra latency and token burn of a reasoning model.
