About MiMo V2 Pro

MiMo V2 Pro is the Pro variant in Xiaomi's MiMo v2 family, released March 18, 2026. Compared to Flash, Pro trades some throughput for more depth on harder tasks.

Like Flash, MiMo V2 Pro uses a Mixture-of-Experts (MoE) architecture, so each forward pass activates a subset of total parameters and keeps per-token compute in check. The model supports a context window of 1M tokens and uses the same hybrid sliding window attention pattern as the rest of the MiMo v2 line, which cuts KV-cache storage versus full attention.

MiMo V2 Pro fits jobs where reasoning depth matters more than peak tokens per second. It handles multi-step math, code generation, and analytical work. You can call it through xiaomi via AI Gateway.
