Nemotron 3 Super 120B A12B vs GPT-4o

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

Nemotron 3 Super 120B A12B is clearly ahead on the aggregate, 61 to 56. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Nemotron 3 Super 120B A12B's sharpest advantage is in coding, where it averages 44.2 against 32.2. The single biggest benchmark swing on the page is SWE-bench Verified, 46 to 20. GPT-4o does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.

GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Nemotron 3 Super 120B A12B. That is roughly Infinityx on output cost alone. Nemotron 3 Super 120B A12B gives you the larger context window at 256K, compared with 128K for GPT-4o.

Quick Verdict

Pick Nemotron 3 Super 120B A12B if you want the stronger benchmark profile. GPT-4o only becomes the better choice if multimodal & grounded is the priority.
