About MiMo V2.5 Pro

MiMo V2.5 Pro is the Pro variant in Xiaomi's MiMo v2.5 family, released April 22, 2026 under the MIT license. Compared to the standard tier, Pro activates a larger share of a larger parameter pool per token, which raises reasoning depth at higher per-token cost.

Like the rest of the line, MiMo V2.5 Pro uses a Mixture-of-Experts (MoE) stack with hybrid attention. Sliding-window and full attention combine in a fixed ratio, which cuts KV-cache storage versus dense attention at the same sequence length. Three multi-token prediction (MTP) blocks raise output tokens per inference step. The full window of 1.1M tokens fits long agent traces, repos, or document sets.

MiMo V2.5 Pro supports reasoning, tool calling, file input, vision, and implicit prompt caching. Call it through xiaomi via AI Gateway. For lower-cost everyday work, see mimo-v2.5.
