Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Qwen3 30B A3B 2507 (Reasoning) | Gemini 2.5 Flash (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.2 | $0.3 |
| Output ($/M tokens) | $2.4 | $2.5 |
Verdict. Qwen3 30B A3B 2507 (Reasoning) and Gemini 2.5 Flash (Reasoning) 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, Qwen3 30B A3B 2507 (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Qwen3 30B A3B 2507 (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Qwen3 30B A3B 2507 (Reasoning) is strongest on Intelligence Index (14.6), Coding Index (12.1). 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 145 tok/s — about 35% faster. On time-to-first-token, Qwen3 30B A3B 2507 (Reasoning) responds in 2340ms vs 19090ms, which matters most for chat-style UIs.
Provider. Alibaba and Google sell to overlapping but distinct developer audiences: Alibaba 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): Qwen3 30B A3B 2507 (Reasoning) costs $42.00 ($504/year); Gemini 2.5 Flash (Reasoning) costs $46.50 ($558/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Qwen3 30B A3B 2507 (Reasoning) ≈ $5.80/run, Gemini 2.5 Flash (Reasoning) ≈ $6.50/run. At agent/realtime scale (200M input / 100M output per million requests): Qwen3 30B A3B 2507 (Reasoning) ≈ $280/run, Gemini 2.5 Flash (Reasoning) ≈ $310/run. Qwen3 30B A3B 2507 (Reasoning) 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.
