Deep dive
On shared benchmark coverage, SWE-bench Verified has Gemini 3.5 Flash at 78 and Nemotron 3 Super-120B-A12B at 60.5, with Gemini 3.5 Flash ahead by 17.5 points; Google-Proof Q&A has Gemini 3.5 Flash at 92.2 and Nemotron 3 Super-120B-A12B at 80, with Gemini 3.5 Flash ahead by 12.2 points. The largest visible gap is 17.5 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: Gemini 3.5 Flash, multimodal input: Gemini 3.5 Flash, reasoning mode: Gemini 3.5 Flash, function calling: Gemini 3.5 Flash, tool use: Gemini 3.5 Flash, and code execution: Gemini 3.5 Flash. 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, Gemini 3.5 Flash lists $1.50/1M input and $9/1M 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 $3.55 per million blended tokens. Availability is 4 providers versus 6, so concentration risk also matters.
Choose Gemini 3.5 Flash when coding workflow support are central to the workload. Choose Nemotron 3 Super-120B-A12B when provider fit, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
