Deep dive
The capability footprint differs most on vision: Xiaomi MiMo-V2.5, reasoning mode: Xiaomi MiMo-V2.5, function calling: Xiaomi MiMo-V2.5, and tool use: Xiaomi MiMo-V2.5. Both models share multimodal input 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, Grok 3 Mini lists $0.3/1M input and $0.5/1M output tokens, while Xiaomi MiMo-V2.5 lists $0.4/1M input and $2/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Grok 3 Mini lower by about $0.52 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 when reasoning depth 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.
FAQ
Which has a larger context window, Grok 3 Mini or Xiaomi MiMo-V2.5?
Xiaomi MiMo-V2.5 supports 1M tokens, while Grok 3 Mini supports 131k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Which is cheaper, Grok 3 Mini or Xiaomi MiMo-V2.5?
Grok 3 Mini is cheaper on tracked token pricing. Grok 3 Mini costs $0.3/1M input and $0.5/1M output tokens. Xiaomi MiMo-V2.5 costs $0.4/1M input and $2/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is Grok 3 Mini or Xiaomi MiMo-V2.5 open source?
