Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | DeepSeek V4 Flash (Reasoning, Max Effort) | Nemotron 3 Nano Omni 30B A3B Reasoning |
|---|---|---|
| Input ($/M tokens) | $0.14 | $0.075 |
| Output ($/M tokens) | $0.28 | $0.3 |
Verdict. DeepSeek V4 Flash (Reasoning, Max Effort) wins the overall benchmark matchup 7–0 across 7 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Both models sit in the budget bracket for output-token pricing. At 0.9× the per-million-token cost, DeepSeek V4 Flash (Reasoning, Max Effort) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). DeepSeek V4 Flash (Reasoning, Max Effort) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. DeepSeek V4 Flash (Reasoning, Max Effort) is strongest on GPQA Diamond (89%), IFBench (79%), Coding Index (56.2). Nemotron 3 Nano Omni 30B A3B Reasoning leads on IFBench (63%), GPQA Diamond (47%), SciCode (28%).
Speed. On throughput, Nemotron 3 Nano Omni 30B A3B Reasoning generates tokens at 323 tok/s versus 111 tok/s — about 66% faster. On time-to-first-token, Nemotron 3 Nano Omni 30B A3B Reasoning responds in 538ms vs 922ms, which matters most for chat-style UIs.
Provider. DeepSeek and NVIDIA sell to overlapping but distinct developer audiences: DeepSeek 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): DeepSeek V4 Flash (Reasoning, Max Effort) costs $8.40 ($101/year); Nemotron 3 Nano Omni 30B A3B Reasoning costs $6.75 ($81/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): DeepSeek V4 Flash (Reasoning, Max Effort) ≈ $1.26/run, Nemotron 3 Nano Omni 30B A3B Reasoning ≈ $0.97/run. At agent/realtime scale (200M input / 100M output per million requests): DeepSeek V4 Flash (Reasoning, Max Effort) ≈ $56/run, Nemotron 3 Nano Omni 30B A3B Reasoning ≈ $45/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. If you want one safe default, take DeepSeek V4 Flash (Reasoning, Max Effort) — it dominates the benchmark table and the latency profile is 2.9× faster. Nemotron 3 Nano Omni 30B A3B Reasoning only makes sense when you specifically need its pricing tier, an existing contract, or a feature difference that is not measured by the benchmarks above.
