Deep dive
On shared benchmark coverage, MMLU PRO has Gemini 3 Pro at 90.1 and Xiaomi MiMo-V2.5-Pro at 68.5, with Gemini 3 Pro ahead by 21.6 points. The largest visible gap is 21.6 points on MMLU PRO, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: Gemini 3 Pro, multimodal input: Gemini 3 Pro, structured outputs: Xiaomi MiMo-V2.5-Pro, and code execution: Gemini 3 Pro. Both models share function calling and tool use, 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, Gemini 3 Pro lists $1.25/1M input and $5/1M output tokens, while Xiaomi MiMo-V2.5-Pro lists $1/1M input and $3/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Xiaomi MiMo-V2.5-Pro lower by about $0.78 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Gemini 3 Pro when coding workflow support and broader provider choice are central to the workload. Choose Xiaomi MiMo-V2.5-Pro when coding workflow support, 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.
