Technical Architecture: MoE Design and Performance Optimization

GLM 5's architecture represents a deliberate engineering approach to balancing capability, efficiency, and scalability. Understanding the technical foundations helps organizations make informed decisions about integration and deployment strategies.

Mixture-of-Experts Architecture

The model employs a Transformer Decoder architecture combined with Mixture-of-Experts (MoE) routing mechanisms. With approximately 745 billion total parameters distributed across the network, the system activates only around 44 billion parameters during each inference operation. This results in a sparsity ratio of 5.9%, meaning the model selectively engages specialized "expert" modules based on input characteristics rather than activating the entire network for every request.

The network structure comprises 78 transformer layers, with each layer containing 256 individual experts. During processing, the routing mechanism intelligently selects 8 experts most relevant to the current input, dynamically composing the model's response capability. This approach delivers massive model capacity while maintaining practical inference costs.

Advanced Attention Mechanisms

GLM 5 implements a hybrid attention strategy optimized for different processing stages. The initial three layers utilize dense attention mechanisms that capture fundamental patterns and relationships within input sequences. Following layers transition to DeepSeek-style Sparse Attention (DSA), which dramatically reduces computational complexity while preserving long-range dependency modeling. This architectural decision enables efficient processing of 128K token contexts without the quadratic computational costs traditionally associated with extended sequences.

Inference Optimization

The model incorporates Multi-Token Prediction (MTP) technology that enables generation of multiple tokens per computational step. Combined with DSA optimization, this delivers approximately 2x throughput improvement compared to standard inference approaches. Development teams benefit from faster response times and reduced computational costs, particularly important for high-volume production deployments.
