MiMo-V2.5 sits inside Xiaomi's MiMo family of open-weights models aimed at developers who need strong reasoning and coding behavior in a deployable package. Xiaomi announced the lineup's flagship, MiMo-V2.5-Pro, as a 1.02T-parameter Mixture-of-Experts model with 42B active parameters, built on a hybrid-attention architecture and a one-the cataloged API limit. The base MiMo-V2.5 sits a step below the Pro variant, sharing the family emphasis on long-horizon coherence and software-engineering ability. Its headlining benchmark, MiMo Coding Bench, is reported at 68.4 for the Pro release, with the broader family positioned against other frontier general and coding systems.

In practical terms, MiMo-V2.5 is geared toward agentic applications, complex software engineering, and long-horizon tasks where maintaining context over very long inputs matters. The model accepts text, images, audio, and video as input and produces text output, supports tool calling, streaming, and structured reasoning, and is delivered with an open-weights license that lets teams self-host or integrate it through third-party APIs. A free public variant exposes these same capabilities with rate limits suitable for experimentation, making it a practical choice for prototype agents, code assistants, and multimodal pipelines that benefit from extended context and explicit reasoning support.
