Deep dive
The capability footprint differs most on vision: Xiaomi MiMo-V2.5, multimodal input: Xiaomi MiMo-V2.5, reasoning mode: Xiaomi MiMo-V2.5, function calling: Xiaomi MiMo-V2.5, tool use: Xiaomi MiMo-V2.5, and structured outputs: Xiaomi MiMo-V2.5. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Doubao Pro 256K lists $0.73/1M input and $1.32/1M output tokens on the cheapest tracked provider, while Xiaomi MiMo-V2.5 lists $0.14/1M input and $0.28/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Xiaomi MiMo-V2.5 lower by about $0.73 per million blended tokens. Availability is 1 providers versus 2, so concentration risk also matters.
Choose Doubao Pro 256K when provider fit are central to the workload. Choose Xiaomi MiMo-V2.5 when reasoning depth, larger context windows, and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
