GLM-4.5 is a multimodal large language model and advanced reasoning system. It functions as an AI coding assistant, an autonomous AI agent, and a multimodal content generator capable of processing and generating text, images, audio, and video within a single unified system.
The project is distinguished by its deep reasoning capabilities, utilizing chain-of-thought processing to solve complex mathematical, logical, and technical problems. It features an agentic architecture that allows for autonomous task execution, long-horizon goal planning, and the ability to interact with external tools and web browsers through iterative reasoning.
Its capability surface includes comprehensive AI software engineering, ranging from automated code generation and bug fixing to performance optimization and documentation. The system also covers professional translation workflows, intelligent document processing, and the creation of high-resolution visual and video content. It further integrates search and indexing through retrieval-augmented generation and repository mapping.
The system provides an API interface compatible with common SDKs and protocols for integration with developer tools.
