GLM-4.5 is a new 355B parameter open-weight MoE model (32B active). It delivers state-of-the-art performance on reasoning, code, and agentic tasks. Both the 355B flagship and a 106B Air version are now available, featuring dual-mode inference.
Today, we introduce two new GLM family members: GLM-4.5 and GLM-4.5-Air — our latest flagship models.
GLM-4.5 is built with 355 billion total parameters and 32 billion active parameters, and GLM-4.5-Air with 106 billion total parameters and 12 billion active parameters. Both are designed to unify reasoning, coding, and agentic capabilities into a single model in order to satisfy more and more complicated requirements of fast rising agentic applications.
We're proud to contribute GLM-4.5 to the open-source community and can't wait to see what developers build with it. Looking forward to your feedback!
