MiMo
Xiaomi's family of open-weight AI models, aimed at long-running agent work and released with downloadable weights.
MiMo is the name Xiaomi gives its family of language models. The models come in pairs: a large Pro version and a smaller, cheaper Flash version, both built as mixture-of-experts systems, meaning only a slice of the model does the work on any given word so that running costs stay manageable. Both take text, images, audio and video, and both hold about a million tokens of context.
What sets MiMo apart from most releases is how much comes with it. Alongside the weights, Xiaomi publishes the technical report, thousands of reinforcement learning task environments and the training framework itself. The models are aimed squarely at agent work, meaning long jobs with many steps and tool calls rather than single questions, and Xiaomi has built a matching coding tool called MiMo Code.
