Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Nemotron 3 Super 120B A12B (Reasoning) | Qwen3.5 Omni Flash |
|---|---|---|
| Input ($/M tokens) | $0.2 | $0.1 |
| Output ($/M tokens) | $0.8 | $0.8 |
Verdict. Nemotron 3 Super 120B A12B (Reasoning) wins the overall benchmark matchup 2–0 across 2 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 1.0× the per-million-token cost, Qwen3.5 Omni Flash is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Qwen3.5 Omni Flash makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Nemotron 3 Super 120B A12B (Reasoning) is strongest on Coding Index (37.7), Intelligence Index (25.7). Qwen3.5 Omni Flash leads on Intelligence Index (19.2).
Speed. On throughput, Qwen3.5 Omni Flash generates tokens at 255 tok/s versus 144 tok/s — about 43% faster. On time-to-first-token, Nemotron 3 Super 120B A12B (Reasoning) responds in 1820ms vs 1840ms, which matters most for chat-style UIs.
Provider. NVIDIA and Alibaba sell to overlapping but distinct developer audiences: NVIDIA tends to ship frontier reasoning models with premium positioning, while Alibaba 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): Nemotron 3 Super 120B A12B (Reasoning) costs $18.00 ($216/year); Qwen3.5 Omni Flash costs $15.00 ($180/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Nemotron 3 Super 120B A12B (Reasoning) ≈ $2.60/run, Qwen3.5 Omni Flash ≈ $2.10/run. At agent/realtime scale (200M input / 100M output per million requests): Nemotron 3 Super 120B A12B (Reasoning) ≈ $120/run, Qwen3.5 Omni Flash ≈ $100/run. Qwen3.5 Omni Flash 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.
