Frequently Asked Questions

  • How does MiMo M2.5 differ from mimo-v2.5-pro?

    MiMo M2.5 is the standard tier. mimo-v2.5-pro activates a larger share of a larger parameter pool per step, so it costs more but reasons further on harder math, code, and agentic problems.

  • What architecture does MiMo M2.5 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 manageable at long context lengths.

  • What's the context window for MiMo M2.5?

    1.1M tokens. Hybrid attention keeps KV-cache memory in check so long-context runs stay practical.

    Yes. MiMo M2.5 supports tool calling and a reasoning mode, both exposed through AI Gateway. Use them through the AI SDK, the Chat Completions API, the Responses API, or any other supported format.
