GLGLM 4.5
GLM 4.5: Zhipu AI's Dual-Mode Reasoning MoE Model
Model Overview
GLM 4.5 is Zhipu AI's flagship open-weights Mixture-of-Experts language model, released in July 2025. With 355 billion total parameters and 32 billion active during inference, GLM 4.5 features a dual-mode reasoning system supporting both fast non-thinking responses and deep agentic thinking modes. It unifies reasoning, coding, and autonomous action capabilities with native tool use and multi-agent workflow support, all under an MIT license.
