MiMo-V2-Pro, V2-Omni and V2-TTS
Xiaomi's first trillion-class model, MiMo-V2-Pro (about 1T total, 42B active), shipped closed alongside an omni model and a speech model.
Pro was released as a proprietary API model; open weights of the same size class followed with V2.5-Pro a month later (1.02T total, 42B active).

Only Wikipedia gives the 2026-03-18 date and proprietary status for V2-Pro; I could not open a Xiaomi launch post. The V2.5-Pro card confirms the 42B-active, ~1T design lineage.
