Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Solar Open2 250B | MiMo-V2.5-Pro |
|---|---|---|
| Input ($/M tokens) | — | $0.43 |
| Output ($/M tokens) | — | $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. Solar Open2 250B is strongest on Coding Index (44.7), Intelligence Index (37.4). MiMo-V2.5-Pro leads on Coding Index (60.2), Intelligence Index (42.9).
Speed. Speed data is incomplete for this pair; benchmark and price should decide.
Provider. Upstage and Xiaomi sell to overlapping but distinct developer audiences: Upstage 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.
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.
Data from Artificial Analysis API — 12 benchmarks
