In-Depth Analysis: Latest Technical Breakthroughs in Domestic Mixture-of-Experts Large Models

    This article explores the innovative architecture, performance benchmarks, and engineering optimizations of China's latest Mixture-of-Experts (MoE) large models, highlighting their computational efficiency improvements and practical applications across coding, multimodal processing, and industrial deployment.

    Architectural Innovations in Mixture-of-Experts Systems

    Dynamic Routing Mechanism

    The MoE architecture employs a two-stage routing strategy:

    1. Gating Network calculates matching scores between input tokens and expert subnetworks
    2. Threshold-based Selection activates relevant experts (e.g., database expert for SQL queries)

    This design maintains 671B parameters while activating only 37B per token, reducing inference energy consumption by >60%. In code generation scenarios, the system automatically routes SQL-related inputs to specialized database experts.

    Expert Subnetwork Design

    The model incorporates 128 expert subnetworks with independent:

    • Transformer decoder architectures
    • Attention weight matrices
    • Feed-forward network parameters

    Through knowledge distillation during pre-training, experts specialize in:

    • Natural language understanding
    • Mathematical reasoning
    • Multimodal data processing

    This specialization enables superior performance in complex tasks requiring combinatorial expertise.

    Progressive Training Strategy

    The training process implements gradual expert activation:

    • Initial phase: 8 experts for foundational capability training
    • Scaling phase: Incremental expert unlocks with training iterations

    This approach stabilizes MoE training, reducing required data volume by 40% while maintaining performance parity.

    6. [x for x in arr if x == pivot] +
    7. quick_sort([x for x in arr if x > pivot]))
    • AST-aware attention mechanism
