What is GLM-4.5?

Z.ai has launched its newest flagship model, GLM-4.5, which features an astounding total of 355 billion parameters (with 32 billion actively utilized) and is accompanied by the GLM-4.5-Air variant, which includes 106 billion parameters (12 billion active) tailored for advanced reasoning, coding, and agent-like functionalities within a unified framework. This innovative model is capable of toggling between a "thinking" mode, ideal for complex, multi-step reasoning and tool utilization, and a "non-thinking" mode that allows for quick responses, supporting a context length of up to 128K tokens and enabling native function calls. Available via the Z.ai chat platform and API, and with open weights on sites like HuggingFace and ModelScope, GLM-4.5 excels at handling diverse inputs for various tasks, including general problem solving, common-sense reasoning, coding from scratch or enhancing existing frameworks, and orchestrating extensive workflows such as web browsing and slide creation. The underlying architecture employs a Mixture-of-Experts design that incorporates loss-free balance routing, grouped-query attention mechanisms, and an MTP layer to support speculative decoding, ensuring it meets enterprise-level performance expectations while being versatile enough for a wide array of applications. Consequently, GLM-4.5 sets a remarkable standard for AI capabilities, pushing the boundaries of technology across multiple fields and industries. This advancement not only enhances user experience but also drives innovation in artificial intelligence solutions.
