Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Reka Flash 3 | Nemotron 3 Super 120B A12B (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.2 | $0.2 |
| Output ($/M tokens) | $0.8 | $0.8 |
Verdict. Nemotron 3 Super 120B A12B (Reasoning) takes the aggregate benchmark matchup 2–0 across 2 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.0× the per-million-token cost, Nemotron 3 Super 120B A12B (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Nemotron 3 Super 120B A12B (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Reka Flash 3 is strongest on Intelligence Index (3.7). Nemotron 3 Super 120B A12B (Reasoning) leads on Coding Index (37.7), Intelligence Index (25.7).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Reka AI and NVIDIA sell to overlapping but distinct developer audiences: Reka AI 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): Reka Flash 3 costs $18.00 ($216/year); Nemotron 3 Super 120B A12B (Reasoning) costs $18.00 ($216/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Reka Flash 3 ≈ $2.60/run, Nemotron 3 Super 120B A12B (Reasoning) ≈ $2.60/run. At agent/realtime scale (200M input / 100M output per million requests): Reka Flash 3 ≈ $120/run, Nemotron 3 Super 120B A12B (Reasoning) ≈ $120/run.
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.
