GLM-4.5
zai-org/glm-4.5
GLM-4.5 Series Models are foundation models specifically engineered for intelligent agents. The flagship GLM-4.5 integrates 355 billion total parameters (32 billion active), unifying reasoning, coding, and agent capabilities to address complex application demands.
As a hybrid reasoning system, it offers dual operational modes:
- Thinking Mode: Enables complex reasoning, tool invocation, and strategic planning
- Non-Thinking Mode: Delivers low-latency responses for real-time interactions
This architecture bridges high-performance AI with adaptive functionality for dynamic agent environments.
