Deploy on demand

The GLM-4.5 series models are foundation models designed for intelligent agents. GLM-4.5 has 355 billion total parameters with 32 billion active parameters, while GLM-4.5-Air adopts a more compact design with 106 billion total parameters and 12 billion active parameters. GLM-4.5 models unify reasoning, coding, and intelligent agent capabilities to meet the complex demands of intelligent agent applications.

GLM-4.5-Air FAQs

GLM-4.5-Air is a compact, open-source large language model developed by Zhipu AI. It is part of the GLM-4.5 family, optimized for intelligent agent applications. GLM-4.5-Air features 106 billion total parameters and 12 billion active parameters and supports hybrid reasoning with two execution modes: “thinking” (for complex tasks) and “non-thinking” (for fast responses).
