Capabilities, design details, and architectural traits

MiMo-V2-Flash - hybrid-attention MiMo model

MiMo-V2-Flash is the series model behind the MiMo-V2.5 design. It is tied to the same long-context architecture and the same hybrid attention and Multi-Token Prediction pattern.

DifferentiatorDocumented trait
Hybrid attentionUses hybrid attention.
Multi-Token PredictionUses Multi-Token Prediction, shortened as MTP.
Long-context designServes as the base for the MiMo-V2.5 context and trajectory design.

Shared design

The model is defined by its architecture rather than a chat-style role. The documented identity is its use in the MiMo series as the source of the hybrid attention and MTP setup.

Series role

MiMo-V2-Flash sits inside Xiaomi MiMo’s model family and connects directly to the V2.5 series. That makes it a structural model in the lineup, not just a named endpoint.
