Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Qwen3 VL 8B (Reasoning) | Mistral Medium 3 |
|---|---|---|
| Input ($/M tokens) | $0.18 | $0.4 |
| Output ($/M tokens) | $2.1 | $2 |
Verdict. Mistral Medium 3 takes the aggregate benchmark matchup 1–0 across 1 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Both models sit in the budget bracket for output-token pricing. At 1.1× the per-million-token cost, Mistral Medium 3 is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Mistral Medium 3 makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Qwen3 VL 8B (Reasoning) is strongest on Intelligence Index (10.5). Mistral Medium 3 leads on Intelligence Index (12.5).
Speed. On throughput, Qwen3 VL 8B (Reasoning) generates tokens at 114 tok/s versus 54 tok/s — about 52% faster. On time-to-first-token, Mistral Medium 3 responds in 1450ms vs 2320ms, which matters most for chat-style UIs.
Provider. Alibaba and Mistral sell to overlapping but distinct developer audiences: Alibaba tends to ship frontier reasoning models with premium positioning, while Mistral 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 VL 8B (Reasoning) costs $36.90 ($443/year); Mistral Medium 3 costs $42.00 ($504/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Qwen3 VL 8B (Reasoning) ≈ $5.10/run, Mistral Medium 3 ≈ $6.00/run. At agent/realtime scale (200M input / 100M output per million requests): Qwen3 VL 8B (Reasoning) ≈ $246/run, Mistral Medium 3 ≈ $280/run. Qwen3 VL 8B (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.
