Deep dive

On shared benchmark coverage, Google-Proof Q&A has Fugu at 95.5 and Nemotron 3 Super-120B-A12B at 80, with Fugu ahead by 15.5 points; LiveCodeBench has Fugu at 92.9 and Nemotron 3 Super-120B-A12B at 78.4, with Fugu ahead by 14.5 points. The largest visible gap is 15.5 points on Google-Proof Q&A, 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: Fugu, multimodal input: Fugu, reasoning mode: Fugu, function calling: Fugu, and tool use: Fugu. 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.

Pricing coverage is uneven: Fugu has no token price sourced yet and Nemotron 3 Super-120B-A12B has $0.09/1M input tokens. Provider availability is 1 tracked routes versus 6. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.

Choose Fugu when reasoning depth are central to the workload. Choose Nemotron 3 Super-120B-A12B when long-context analysis, larger context windows, 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.

FAQ

Which has a larger context window, Fugu or Nemotron 3 Super-120B-A12B?

Nemotron 3 Super-120B-A12B supports 1.05m tokens, while Fugu supports 1m tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Is Fugu or Nemotron 3 Super-120B-A12B open source?

Fugu is listed under Proprietary. Nemotron 3 Super-120B-A12B is listed under NVIDIA Open Model. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.

Which is better for vision, Fugu or Nemotron 3 Super-120B-A12B?

Fugu has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.

Which is better for multimodal input, Fugu or Nemotron 3 Super-120B-A12B?

Fugu has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Which is better for reasoning mode, Fugu or Nemotron 3 Super-120B-A12B?

Fugu has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Where can I run Fugu and Nemotron 3 Super-120B-A12B?

Fugu is available on Sakana AI. Nemotron 3 Super-120B-A12B is available on Cloudflare Workers AI, DeepInfra, NVIDIA NIM, OpenRouter, and Fireworks AI. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
