Frequently Asked Questions

  • How does MiMo V2.5 Pro differ from mimo-v2.5?

    It's the Pro tier. MiMo V2.5 Pro activates a larger share of a larger parameter pool per token than mimo-v2.5, with higher per-token cost in return for stronger reasoning, code, and agentic scores.

  • What architecture does MiMo V2.5 Pro use?

    A Mixture-of-Experts (MoE) stack with hybrid attention. Each token activates a subset of expert blocks, and sliding-window plus full attention combine to keep KV-cache storage manageable across the 1.1M tokens window.

  • What's the context window for MiMo V2.5 Pro?

    1.1M tokens. Hybrid attention keeps long-context runs practical, and multi-token prediction raises output tokens per inference step.

  • Does MiMo V2.5 Pro support tool calling and reasoning modes?

    Yes. MiMo V2.5 Pro supports reasoning and tool calling, both exposed through AI Gateway. Use them through the AI SDK, the Chat Completions API, the Responses API, or any other supported format.

  • How do I authenticate requests to MiMo V2.5 Pro through AI Gateway?

    Add your API key in AI Gateway project settings. Use xiaomi/mimo-v2.5-pro in API calls. AI Gateway routes, retries, and fails over across xiaomi.

  • What does MiMo V2.5 Pro cost?

    See the pricing section on this page for today's rates. AI Gateway tracks each provider's pricing for MiMo V2.5 Pro, so the numbers shown stay current.

  • Does MiMo V2.5 Pro support zero data retention?

    Zero Data Retention is not currently available for this model. Zero Data Retention is offered on a per-provider basis. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.

  • Can I route between MiMo V2.5 Pro and mimo-v2.5 automatically?

    Yes. AI Gateway supports fallback and routing. Send hard reasoning, code, and agentic requests to MiMo V2.5 Pro and fall back to mimo-v2.5 for simpler tasks to keep costs in check.
