Deployment Guide and Performance Evaluation for GLM-5.2 with MoE Architecture
This guide provides practical insights into deploying GLM-5.2, a trillion-parameter language model using Mixture of Experts (MoE) architecture, covering hardware selection, optimization strategies, and production-grade adaptation techniques for different business scenarios.
Model Architecture and Core Parameters
GLM-5.2 implements a MoE architecture with 744B total parameters, dynamically activating only 40B parameters during inference through gating mechanisms. This design maintains model capacity while significantly reducing computational overhead. Key considerations:
- Memory Consumption: Actual GPU memory usage includes full model weights (inactive experts included), KV cache (intermediate attention states), and concurrent request overhead. Processing 1M-token contexts may require tens of GBs for KV cache alone
- Parameter Efficiency: Expert grouping and sparse activation enable loading partial weights during inference, demanding specific requirements for memory bandwidth and compute parallelism
