Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Nova 2.0 Pro Preview (medium) | Gemini 2.5 Pro |
|---|---|---|
| Input ($/M tokens) | $1.25 | $1.25 |
| Output ($/M tokens) | $10 | $10 |
Verdict. Nova 2.0 Pro Preview (medium) and Gemini 2.5 Pro 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 mid-tier bracket for output-token pricing. At 1.0× the per-million-token cost, Gemini 2.5 Pro is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Gemini 2.5 Pro makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Nova 2.0 Pro Preview (medium) is strongest on Coding Index (34.0), Intelligence Index (22.1). Gemini 2.5 Pro leads on Coding Index (33.3), Intelligence Index (25.9).
Speed. Throughput is comparable — 115 tok/s vs 133 tok/s — so generation speed shouldn't drive your choice here. Look at the per-benchmark wins instead.
Provider. Amazon and Google sell to overlapping but distinct developer audiences: Amazon tends to ship frontier reasoning models with premium positioning, while Google 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): Nova 2.0 Pro Preview (medium) costs $187.50 ($2250/year); Gemini 2.5 Pro costs $187.50 ($2250/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Nova 2.0 Pro Preview (medium) ≈ $26.25/run, Gemini 2.5 Pro ≈ $26.25/run. At agent/realtime scale (200M input / 100M output per million requests): Nova 2.0 Pro Preview (medium) ≈ $1250/run, Gemini 2.5 Pro ≈ $1250/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.
