Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Qwen3.5 122B A10B (Non-reasoning) | Gemini 3 Flash Preview (Reasoning) |
|---|---|---|
| Input ($/M tokens) | $0.4 | $0.5 |
| Output ($/M tokens) | $3.2 | $3 |
Verdict. Qwen3.5 122B A10B (Non-reasoning) and Gemini 3 Flash Preview (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 1.1× the per-million-token cost, Gemini 3 Flash Preview (Reasoning) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Gemini 3 Flash Preview (Reasoning) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Qwen3.5 122B A10B (Non-reasoning) is strongest on Coding Index (43.3), Intelligence Index (28.2). Gemini 3 Flash Preview (Reasoning) leads on Intelligence Index (38.7).
Speed. On throughput, Gemini 3 Flash Preview (Reasoning) generates tokens at 189 tok/s versus 143 tok/s — about 25% faster. On time-to-first-token, Qwen3.5 122B A10B (Non-reasoning) responds in 2330ms vs 6570ms, 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): Qwen3.5 122B A10B (Non-reasoning) costs $60.00 ($720/year); Gemini 3 Flash Preview (Reasoning) costs $60.00 ($720/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Qwen3.5 122B A10B (Non-reasoning) ≈ $8.40/run, Gemini 3 Flash Preview (Reasoning) ≈ $8.50/run. At agent/realtime scale (200M input / 100M output per million requests): Qwen3.5 122B A10B (Non-reasoning) ≈ $400/run, Gemini 3 Flash Preview (Reasoning) ≈ $400/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.
