Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Mistral Small 3.1 | Nemotron 3 Nano Omni 30B A3B Reasoning |
|---|---|---|
| Input ($/M tokens) | $0.1 | $0.07 |
| Output ($/M tokens) | $0.3 | $0.3 |
Verdict. Mistral Small 3.1 and Nemotron 3 Nano Omni 30B A3B Reasoning split the benchmark comparison evenly at 1–1. The tiebreaker here is price, speed, and what you actually run them on.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, Nemotron 3 Nano Omni 30B A3B Reasoning is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Nemotron 3 Nano Omni 30B A3B Reasoning makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Mistral Small 3.1 is strongest on Coding Index (26.3), Intelligence Index (14.9). Nemotron 3 Nano Omni 30B A3B Reasoning leads on Intelligence Index (15.0), Coding Index (13.8).
Speed. On throughput, Nemotron 3 Nano Omni 30B A3B Reasoning generates tokens at 326 tok/s versus 149 tok/s — about 54% faster. On time-to-first-token, Mistral Small 3.1 responds in 810ms vs 1040ms, which matters most for chat-style UIs.
Provider. Mistral and NVIDIA sell to overlapping but distinct developer audiences: Mistral tends to ship frontier reasoning models with premium positioning, while NVIDIA often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
Workload cost. Workload scenarios (per million requests at 30M input + 15M output tokens): Mistral Small 3.1 costs $7.50 ($90/year); Nemotron 3 Nano Omni 30B A3B Reasoning costs $6.60 ($79/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Mistral Small 3.1 ≈ $1.10/run, Nemotron 3 Nano Omni 30B A3B Reasoning ≈ $0.95/run. At agent/realtime scale (200M input / 100M output per million requests): Mistral Small 3.1 ≈ $50/run, Nemotron 3 Nano Omni 30B A3B Reasoning ≈ $44/run. Nemotron 3 Nano Omni 30B A3B Reasoning becomes more attractive at higher volume — the absolute per-token pricing difference compounds when you ship at scale.
Recommendation. Both models have legitimate use cases — the right answer depends on whether you are optimizing for benchmark ceiling, latency, or unit cost. Start with the cheaper / faster model, evaluate against your specific task, and only switch if the upgrade shows a meaningful lift.
