Xiaomi MiMo

What is Xiaomi MiMo?

Xiaomi MiMo is Xiaomi's family of large foundation models designed to power intelligent agent systems in real-world scenarios. The latest V2 series comprises three specialized models: MiMo-V2-Pro, a trillion-parameter flagship engineered for complex agentic workloads with a 1M-token context window; MiMo-V2-Omni, a natively multimodal base model that integrates text, vision, and audio perception into a unified agent pipeline; and MiMo-V2-TTS, a speech synthesis model with fine-grained, multi-level voice style control. Together, the suite covers the full chain from reasoning and perception to execution and voice output. All models are accessible via API and a web demo, with open-source releases planned.

Key Features

• Frontier Agentic Reasoning

  MiMo-V2-Pro features 1T total parameters (42B activated), a hybrid attention architecture, and a 1M-token context window — ranked #8 globally on the Artificial Analysis Intelligence Index and #1 among Chinese LLMs on real-world agentic benchmarks (GDPval-AA).

• Full-Stack Omnimodal Perception

  MiMo-V2-Omni natively fuses text, vision, and audio understanding, supporting audio-visual joint reasoning, multi-speaker separation, and continuous audio comprehension beyond 10 hours — outperforming Gemini 3 Pro on audio understanding benchmarks.

• Expressive Speech Synthesis

  MiMo-V2-TTS uses a proprietary Audio Tokenizer and multi-codebook speech-text joint modeling, enabling multi-level voice style control — from overall tone to mid-sentence emotion shifts — with accurate pitch and rhythm in singing.

• Agent Framework Integration

  MiMo-V2-Pro serves as the native brain of OpenClaw and integrates with frameworks including OpenCode, KiloCode, Blackbox, and Cline, achieving globally leading scores on PinchBench and ClawEval.

• API & Developer Access

  All three models are available via the MiMo developer platform (platform.xiaomimimo.com), with OpenAI-compatible APIs and integration into Xiaomi's own products such as MiMo Studio and Xiaomi Browser.

Use Cases

• Autonomous Agent Workflows : Engineering teams and enterprises can deploy MiMo-V2-Pro as the reasoning core of agent systems — handling multi-step task planning, tool calling, and production-grade software engineering with minimal human intervention.
• Multimodal Content Understanding : Developers building applications that require joint interpretation of video, audio, and text — such as meeting analysis, media monitoring, or accessibility tools — can leverage MiMo-V2-Omni's unified perception pipeline.
• Intelligent Voice Applications : Product teams can use MiMo-V2-TTS to build voice assistants, audiobook narration tools, or character dialogue systems with nuanced emotional expression and dialect support.
• Complex Coding & Engineering : Software developers can use MiMo-V2-Pro for high-intensity coding tasks, where its coding ability surpasses Claude 4.6 Sonnet and its 1M-token context handles large codebases in a single pass.
• Productivity Platform Integration : Office and enterprise software vendors (e.g., Kingsoft Office) can embed MiMo models into document editing, summarization, and workflow automation via standardized API access.
