Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Nova 2.0 Lite (high) | Gemini 2.5 Flash (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.3 | $0.3 |
| Output ($/M tokens) | $2.5 | $2.5 |
Verdict. Nova 2.0 Lite (high) 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, Gemini 2.5 Flash (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Gemini 2.5 Flash (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Nova 2.0 Lite (high) is strongest on Coding Index (23.0), Intelligence Index (20.8). Gemini 2.5 Flash (Reasoning) leads on Intelligence Index (20.3).
Speed. On throughput, Gemini 2.5 Flash (Reasoning) generates tokens at 225 tok/s versus 156 tok/s — about 31% faster. On time-to-first-token, Nova 2.0 Lite (high) responds in 10980ms vs 19090ms, which matters most for chat-style UIs.
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 Lite (high) costs $46.50 ($558/year); Gemini 2.5 Flash (Reasoning) costs $46.50 ($558/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Nova 2.0 Lite (high) ≈ $6.50/run, Gemini 2.5 Flash (Reasoning) ≈ $6.50/run. At agent/realtime scale (200M input / 100M output per million requests): Nova 2.0 Lite (high) ≈ $310/run, Gemini 2.5 Flash (Reasoning) ≈ $310/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.
