Deep dive
The capability footprint differs most on function calling: Mistral Small 3 and tool use: Mistral Small 3. 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, Mistral Small 3 lists $0.10/1M input and $0.30/1M output tokens on the cheapest tracked provider, while Nemotron 4 340B lists $4.20/1M input and $4.20/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral Small 3 lower by about $4.04 per million blended tokens. Availability is 2 providers versus 2, so concentration risk also matters.
Choose Mistral Small 3 when long-context analysis, larger context windows, and lower input-token cost are central to the workload. Choose Nemotron 4 340B when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
FAQ
Which has a larger context window, Mistral Small 3 or Nemotron 4 340B?
Mistral Small 3 supports 33k tokens, while Nemotron 4 340B supports 4k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, Mistral Small 3 or Nemotron 4 340B?
Mistral Small 3 is cheaper on tracked token pricing. Mistral Small 3 costs $0.10/1M input and $0.30/1M output tokens. Nemotron 4 340B costs $4.20/1M input and $4.20/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is Mistral Small 3 or Nemotron 4 340B open source?
Mistral Small 3 is listed under Apache 2.0. Nemotron 4 340B 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 function calling, Mistral Small 3 or Nemotron 4 340B?
Mistral Small 3 has the clearer documented function calling signal in this comparison. If function calling is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for tool use, Mistral Small 3 or Nemotron 4 340B?
Mistral Small 3 has the clearer documented tool use signal in this comparison. If tool use is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run Mistral Small 3 and Nemotron 4 340B?
Mistral Small 3 is available on Together AI and Vercel AI Gateway. Nemotron 4 340B is available on NVIDIA NIM and DeepInfra. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
