About MiMo-V2.5-Pro

MiMo-V2.5-Pro is Xiaomi's proprietary LLM built exclusively for text modality. Its closed-source design limits direct access while providing managed API usage. The system accommodates sequences reaching exactly 1,048,576 tokens.

A core strength is sustained coherence across very long inputs without external chunking. This reduces preprocessing steps for users working with full documents or multi-turn histories. Performance remains stable even when context fills most of the available window.

Common applications include legal document analysis, technical report summarization, and enterprise chat systems. Integrators deploy it where retaining full context improves output quality. The model fits production environments that prioritize capacity over open-weight flexibility.
