MiMo V2 Pro
MiMo V2 Pro is the Pro variant in Xiaomi's MiMo v2 family with over 1T total parameters and 42B active, built for math, code, and multi-step reasoning within a context window of 1M tokens. It uses a hybrid attention architecture for long-context processing.

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.
What To Consider When Choosing a Provider
- Configuration: MiMo V2 Pro sits at the Pro end of the MiMo v2 lineup. It costs more per token than Flash, but it fits when accuracy matters more than price. Use AI Gateway's cost tracking and model fallback to route easy work to Flash and harder work to Pro.
- Zero Data Retention: AI Gateway does not currently support Zero Data Retention for this model. See the documentation for models that support ZDR.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
When to Use MiMo V2 Pro
Best For
- Multi-step reasoning: You care more about accuracy on hard problems than raw throughput
- Code generation: Architecture design, debugging, and multi-file refactors
- Math and proofs: Problems that require long logical chains where intermediate reasoning steps matter
- Long-context work: A window of 1M tokens fits big documents or repos
- Pro-tier MoE: Over 1T total parameters with 42B active per forward pass
Consider Alternatives When
- Speed-first simple tasks: The Flash variant fits better when cost and throughput drive the choice
- Multimodal input required: MiMo V2 Pro is text-in, text-out only
- Simple classification jobs: A smaller, cheaper model handles extraction at lower cost
Conclusion
MiMo V2 Pro is the Pro pick in Xiaomi's MiMo v2 lineup. Use it for multi-step math, multi-step code, and analytical work. Pair it with Flash through AI Gateway routing so you can balance cost and quality.
