MiMo-V2.6-Pro-UltraSpeed is Xiaomi's high-throughput variant of its flagship omnimodal model, rolled out alongside MiMo-V2.6-Pro and MiMo-V2.6-Flash as part of the same series release. Where Pro is positioned as Xiaomi's most capable model and Flash as the efficiency-tuned counterpart, UltraSpeed is specifically optimized for extreme generation speed, delivering up to 20x faster output at the same quality level. This makes it a practical fit for latency-sensitive workloads such as interactive agents, large-batch content generation, and real-time coding assistance where throughput matters more than absolute peak capability.
The UltraSpeed variant inherits the broader MiMo-V2.6 design philosophy of natively omnimodal input handling with text output, built within a publicly open-sourced series that Xiaomi describes as a step along an RSI path focused on scaling reinforcement learning compute on verifiable, complex tasks. On the coding benchmarks Xiaomi reports alongside the release, the underlying MiMo-V2.6-Pro posts competitive scores including 71.9 on DeepSWE v1.1 and 63.2 on the in-house MiMo Code Bench, giving UltraSpeed a strong quality baseline to draw from while its speed-focused optimizations take priority. In practical terms, it is best understood as a deployment-oriented sibling for teams that want frontier-class reasoning and coding ability without sacrificing responsiveness.
