Official Z.ai platform to experience our new, MIT-licensed GLM models (Base, Reasoning, Rumination). Simple UI focuses on model interaction. Free.

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!
@zixuan_lii How well does it scale with multi-agent setups
Any memory limits users should watch for

@masump The context window is 128K. For specialized scenarios, we use a single-agent solution where the GLM-4.5 model continuously thinks and calls tools, using the results as context for its subsequent actions.
@zixuan_lii Impressive work, Zixuan! Excited to see GLM-4.5 and 4.5-Air pushing boundaries in unified reasoning, coding, and agentic performance. Open-sourcing such a powerful model is a huge step forward for the AI community—looking forward to exploring its capabilities!

Congrats on the launch! GLM-4.5 could be a major step forward in unifying reasoning, coding, and agentic capabilities. Open-source models are the future.

@sig_eternal Thanks Sig! Open Source is all we need. 🙌
For the past few years, the GLM model series from the Zhipu team (now Z.ai) has been one of the favorites in the open-source community, often as a great, affordable option. With GLM-4.5, however, it's clear they're now aiming for the top.
So, long story short: imagine a model with the agentic coding capabilities like Claude 4, but 2-3x faster, 10x cheaper (based on official API prices), and it's completely open-source.
This. is. simply wild. 🫡
