Deep dive
On shared benchmark coverage, Google-Proof Q&A has Gemini 3.1 Flash-Lite at 86.9 and Xiaomi MiMo-V2.5-Pro at 66.7, with Gemini 3.1 Flash-Lite ahead by 20.2 points. The largest visible gap is 20.2 points on Google-Proof Q&A, 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 3.1 Flash-Lite, multimodal input: Gemini 3.1 Flash-Lite, and code execution: Gemini 3.1 Flash-Lite. 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, Gemini 3.1 Flash-Lite lists $0.25/1M input and $1.5/1M 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 Gemini 3.1 Flash-Lite lower by about $0.97 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Gemini 3.1 Flash-Lite when coding workflow support, lower input-token cost, and broader provider choice are central to the workload. Choose Xiaomi MiMo-V2.5-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.
