About the model

MiMo v2.5 Pro is the flagship model of Xiaomi's MiMo line, delivering higher quality than the family's base variant. It lays out a step-by-step breakdown for complex multi-step tasks and is especially helpful with code: it generates, explains and refactors it, finds bugs and suggests fixes. Its very large context window holds bulky technical materials, large portions of a project and long conversations. The model calls tools reliably (function-calling) and is suited to agents in development and automation. It is multilingual and handles Russian at a medium level.
