MiMo V2 Pro
MiMo V2 Pro is Xiaomi’s hosted flagship for long-running software engineering and agent tasks. Its trillion-scale sparse backbone activates approximately 42B parameters and combines sliding-window and global attention. The text model supports up to 1M tokens and structured tool use. Anonymous evaluation names such as Hunter Alpha are aliases, rather than separate releases. Xiaomi provides API and chat access; the V2 Pro weights were not publicly released alongside the later V2.5 family.
