Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Devstral 2 | MiMo-V2.5-Pro |
|---|---|---|
| Input ($/M tokens) | $0 | $0.43 |
| Output ($/M tokens) | $0 | $0.87 |
Verdict. MiMo-V2.5-Pro takes the aggregate benchmark matchup 2–0 across 2 categories. Real workloads usually care about a handful of specific tasks — see the per-benchmark table above.
Pricing. Pricing varies significantly between these models — check the table above for the exact per-token rates. Many production workloads actually surface input-token cost (retrieval-augmented prompts, code-context windows), so factor both directions.
Strengths. Devstral 2 is strongest on Coding Index (31.3), Intelligence Index (19.2). MiMo-V2.5-Pro leads on Coding Index (60.2), Intelligence Index (42.9).
Speed. On throughput, Devstral 2 generates tokens at 119 tok/s versus 35 tok/s — about 70% faster. On time-to-first-token, Devstral 2 responds in 2330ms vs 4070ms, which matters most for chat-style UIs.
Provider. Mistral and Xiaomi sell to overlapping but distinct developer audiences: Mistral tends to ship frontier reasoning models with premium positioning, while Xiaomi 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): Devstral 2 costs $0.00 ($0/year); MiMo-V2.5-Pro costs $25.95 ($311/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Devstral 2 ≈ $0.00/run, MiMo-V2.5-Pro ≈ $3.89/run. At agent/realtime scale (200M input / 100M output per million requests): Devstral 2 ≈ $0/run, MiMo-V2.5-Pro ≈ $173/run. Devstral 2 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.
