Xiaomi: MiMo Models, Open Weights and Hosted AI

MiMo inside an electronics company

Xiaomi was founded in April 2010 and listed in Hong Kong in July 2018. Its business combines smartphones, electric vehicles and connected hardware. MiMo is the company’s foundation-model work within a broader software, chips and device strategy, rather than a separate company. [1]

The MiMo-V2.6 release includes Pro and Flash multimodal models and hosted APIs. The official MiMo-V2.6-Pro-RL checkpoint lists the MIT license, allowing readers to distinguish an actual public weight artifact from paid hosted access. That checkpoint’s terms should not be generalized to every Xiaomi model or service. [2][3]

Xiaomi also published reinforcement-learning resources for V2.6 and described a six-day live RL run. Its reported training costs concern that reinforcement-learning stage; they do not establish the full cost of pretraining, prior research or all development of the model family. [2]
