Xiaomi MiMo-V2.5-Pro vs o3-pro
Xiaomi MiMo-V2.5-Pro (2026) and o3-pro (2025) are agentic coding models from Xiaomi and OpenAI. Xiaomi MiMo-V2.5-Pro ships a 1M-token context window, while o3-pro ships a not-yet-sourced context window. On pricing, Xiaomi MiMo-V2.5-Pro costs $1/1M input tokens versus $20/1M for the alternative. This comparison covers specs, pricing, capabilities, benchmarks, provider availability, and production fit. It focuses on practical selection signals rather than broad model-family marketing.
Xiaomi MiMo-V2.5-Pro is ~1900% cheaper at $1/1M; pay for o3-pro only for coding workflow support.

Deep dive
The capability footprint differs most on vision: o3-pro, multimodal input: o3-pro, reasoning mode: o3-pro, and code execution: o3-pro. Both models share function calling, tool use, and structured outputs, 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, Xiaomi MiMo-V2.5-Pro lists $1/1M input and $3/1M output tokens, while o3-pro lists $20/1M input and $80/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Xiaomi MiMo-V2.5-Pro lower by about $36.40 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose Xiaomi MiMo-V2.5-Pro when coding workflow support and lower input-token cost are central to the workload. Choose o3-pro when coding workflow support 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. It also helps separate model capability from provider packaging, which can change cost and latency.
FAQ
Which is cheaper, Xiaomi MiMo-V2.5-Pro or o3-pro?
Xiaomi MiMo-V2.5-Pro is cheaper on tracked token pricing. Xiaomi MiMo-V2.5-Pro costs $1/1M input and $3/1M output tokens. o3-pro costs $20/1M input and $80/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is Xiaomi MiMo-V2.5-Pro or o3-pro open source?
Xiaomi MiMo-V2.5-Pro is listed under Proprietary. o3-pro is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Xiaomi MiMo-V2.5-Pro or o3-pro?
o3-pro has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Which is better for multimodal input, Xiaomi MiMo-V2.5-Pro or o3-pro?
o3-pro has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for reasoning mode, Xiaomi MiMo-V2.5-Pro or o3-pro?
o3-pro has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run Xiaomi MiMo-V2.5-Pro and o3-pro?
Xiaomi MiMo-V2.5-Pro is available on OpenRouter. o3-pro is available on OpenRouter. Provider coverage can affect latency, region availability, compliance posture, and fallback options. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
