Key Highlights

  • Trillion Parameters: MiMo-V2-Pro has 1T+ total parameters, 42B active, MoE architecture
  • Near-Top Performance: AA Intelligence Index 49 (#8 globally), ClawEval 61.5 approaching Opus 4.6 (66.3), coding surpasses Sonnet 4.6
  • 1/6th the Price: Pro at $1 input / $3 output per M tokens — roughly 1/6th of GPT-5.2 and Opus 4.6
  • Full Multimodal: MiMo-V2-Omni accepts text, image, video, and audio — with 10+ hours continuous audio understanding
  • 1M Context: Pro supports 1 million token context window

Background

On March 18-19, 2026, Xiaomi officially launched the MiMo-V2 model family. MiMo-V2-Pro had previously been circulating anonymously on OpenRouter under the codename “Hunter Alpha”, generating significant buzz before Xiaomi claimed ownership. MiMo-V2-Pro is designed as an agentic foundation model optimized for orchestrating complex workflows, tool use, and code execution. MiMo-V2-Omni is a unified multimodal model that natively processes text, image, video, and audio — claimed to be the first omni model supporting 10+ hours of continuous audio understanding. Both models are now available on API Yi.

Summary & Recommendations

The MiMo-V2 series is Xiaomi’s major AI play. Pro approaches Opus 4.6 on agentic benchmarks with its trillion-parameter architecture and 1M context, at just 1/6th the price. Omni’s unified multimodal understanding — especially 10+ hour audio — stands out among competitors. Recommendation: Choose Pro for high-value reasoning and coding tasks. Choose Omni for multimodal understanding, especially audio and video.
MiMo-V2 series was recently launched. Implement proper error handling for production use and watch for updates.
