xiaomi’s mimo open platform has officially announced that, as of june 30, 2026, it will completely discontinue support for the four core models in the mimo‑v2 series, while simultaneously transitioning to the v2.5 series, which features enhanced performance and capabilities. this phase-out includes mimo‑v2‑pro, mimo‑v2‑omni, mimo‑v2‑flash, and mimo‑v2‑tts. the platform has already published a detailed migration roadmap and timeline on its official website.
all v2‑series models will be officially retired at 00:00 beijing time on june 30, 2026. at that point, api calls will return error responses, so developers are required to complete model name updates and interface adaptations before then. to minimize migration costs, the platform has introduced an “intelligent routing transition period”: after the designated system replacement date, requests directed to the old models will automatically be forwarded to their corresponding new‑version counterparts, billed according to the v2.5 series pricing standards.
the specific schedule is as follows: starting at 00:00 on june 1, 2026, mimo‑v2‑pro and mimo‑v2‑omni will enable automatic routing, connecting respectively to mimo‑v2.5‑pro and mimo‑v2.5; these two versions maintain full api parameter compatibility, requiring no code modifications. meanwhile, mimo‑v2‑flash and mimo‑v2‑tts will begin routing transitions at 00:00 on june 18, with the former redirecting to mimo‑v2.5 and the latter integrating into mimo‑v2.5‑tts.
it is worth noting that, following the upgrade from mimo‑v2‑tts to mimo‑v2.5‑tts, the voice‑tone system has been entirely restructured. the new model employs a region‑aware mapping strategy: within the china cluster, the default tone “mimo_default” is uniformly mapped to the “bingtang” voice; overseas clusters, by default, map to “mia.” developers must update their tone configurations accordingly to avoid disruptions in voice services.
