Deep dive
The capability footprint differs most on multimodal input: Grok 3 Mini, function calling: Xiaomi MiMo-V2.5-Pro, and tool use: Xiaomi MiMo-V2.5-Pro. Both models share 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, Grok 3 Mini lists $0.3/1M input and $0.5/1M 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 Grok 3 Mini lower by about $1.24 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose Grok 3 Mini when provider fit and lower input-token cost are central to the workload. Choose Xiaomi MiMo-V2.5-Pro when coding workflow support and larger context windows 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.
