Deep dive
On shared benchmark coverage, SWE-bench Verified has GPT-4.1 Mini at 23.6 and Nemotron 3 Super-120B-A12B at 60.5, with Nemotron 3 Super-120B-A12B ahead by 36.9 points. The largest visible gap is 36.9 points on SWE-bench Verified, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: GPT-4.1 Mini, multimodal input: GPT-4.1 Mini, function calling: GPT-4.1 Mini, tool use: GPT-4.1 Mini, and code execution: GPT-4.1 Mini. Both models share structured outputs, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, GPT-4.1 Mini lists $0.40/1M input and $1.60/1M output tokens on the cheapest tracked provider, while Nemotron 3 Super-120B-A12B lists $0.09/1M input and $0.45/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Nemotron 3 Super-120B-A12B lower by about $0.56 per million blended tokens. Availability is 4 providers versus 6, so concentration risk also matters.
Choose GPT-4.1 Mini when coding workflow support are central to the workload. Choose Nemotron 3 Super-120B-A12B when long-context analysis, larger context windows, and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
