MiMo-V2-Flash

Product Introduction

1. Definition: MiMo-V2-Flash is a 309-billion-parameter Mixture of Experts (MoE) large language model (LLM) developed by Xiaomi, with 15 billion active parameters during inference. It belongs to the foundation model category for AI-driven language processing.
2. Core Value Proposition: MiMo-V2-Flash delivers unprecedented efficiency and speed for complex AI tasks, excelling in reasoning, coding, and agentic workflows while serving as a versatile assistant for daily use. Its primary value lies in balancing massive scale with computational efficiency.

Main Features

1. Mixture of Experts Architecture:
   • How it works: Activates only 15B of its 309B parameters per task via dynamic routing, reducing computational load.
   • Technologies: Sparse activation, expert gating networks, and parameter-efficient fine-tuning (PEFT).
2. Ultra-Fast Inference Engine:
   • How it works: Leverages hardware-aware optimizations (e.g., tensor parallelism, kernel fusion) for sub-second latency.
   • Technologies: CUDA-accelerated inference, FlashAttention-v2, and quantization-aware training (INT8/FP16).
3. Reasoning & Coding Specialization:
   • How it works: Trained on curated datasets (e.g., GitHub code, mathematical proofs) using chain-of-thought (CoT) prompting.
   • Technologies: Reinforcement Learning from Human Feedback (RLHF) for code refinement and Tree-of-Thoughts reasoning.

Problems Solved

1. Pain Point: High computational costs and latency in large-scale LLMs hinder real-time agentic applications (e.g., coding assistants, automated workflows).
2. Target Audience:
   • AI researchers needing efficient model experimentation.
   • Developers building real-time coding tools (e.g., IDEs, DevOps).
   • Enterprises deploying AI agents for customer service automation.
3. Use Cases:
   • Real-time code generation/debugging in integrated development environments (IDEs).
   • Multi-step reasoning for data analysis or scientific research.
   • Low-latency conversational agents for customer support.

Unique Advantages

1. Differentiation: Outperforms dense models (e.g., LLaMA-70B) with 4× faster inference at comparable accuracy and surpasses smaller MoEs (e.g., Mixtral) in complex reasoning benchmarks like GSM8K and HumanEval.
2. Key Innovation: Xiaomi’s proprietary "Dynamic Expert Routing" algorithm minimizes parameter redundancy while maintaining 309B knowledge breadth, achieving 40% higher tokens/sec than comparable MoEs.
