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!
Great. Even more great that you guys made it open source. It's the future. One question: Is there any way we can integrate it in our own web apps like any other LLMs? If there is, is it compatible with popular wrappers which can be used to use most LLMs out there without using any other wrapper?
I am amazed by the capabilities of 4.5, and it feels like a significant improvement over the previous generation.
The agentic capability is very promising. We can build slides and websites very quickly with just a few sentences.
Strong coding ability, able to generate small games with just one sentence, including full stack code for both front-end and back-end
It's amazing! I've used it to develop several small games and have been enjoying myself a lot.
GLM-4.5 is a powerful and versatile AI assistant that handles both text and images impressively. Its responses are fluent, context-aware, and helpful for everyday tasks like writing, learning, and brainstorming.
However, it can sometimes be overly verbose or a bit too confident in its answers, even when they’re slightly off. While not perfect, it’s one of the better models I’ve used recently—great for personal use if you’re looking for a smart, flexible tool.
As a liberal arts student, this ai enabled me to effortlessly write the games in my mind. It's extremely convenient . I hope more people like me who don't know programming can use this ai to realize their own ideas
GLM-4.5 is an impressive advancement in the open-source large language model landscape. Building on the strengths of its predecessors, it demonstrates notable improvements in reasoning, code generation, and multilingual understanding.
Congratulations on the launch! Open source is the optimal path to drive the era forward, enabling global mutual benefit.
@zixuan_lii Great Product! But a little bit slow compared to other Open AI Models.
What a powerful model that high performence to fully support agent workflow building.
