Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Hy3-preview (Non-reasoning) | Nemotron 3.5 Lightning |
|---|---|---|
| Input ($/M tokens) | $0.06 | $0.06 |
| Output ($/M tokens) | $0.21 | $0.2 |
Verdict. Hy3-preview (Non-reasoning) and Nemotron 3.5 Lightning 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 3.5 Lightning is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Nemotron 3.5 Lightning makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Hy3-preview (Non-reasoning) is strongest on Intelligence Index (17.0). Nemotron 3.5 Lightning leads on Coding Index (26.8), Intelligence Index (13.6).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Tencent and NVIDIA sell to overlapping but distinct developer audiences: Tencent 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): Hy3-preview (Non-reasoning) costs $4.95 ($59/year); Nemotron 3.5 Lightning costs $4.80 ($58/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Hy3-preview (Non-reasoning) ≈ $0.72/run, Nemotron 3.5 Lightning ≈ $0.70/run. At agent/realtime scale (200M input / 100M output per million requests): Hy3-preview (Non-reasoning) ≈ $33/run, Nemotron 3.5 Lightning ≈ $32/run. Nemotron 3.5 Lightning 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.
Head-to-head deltas
