GLM-5.3 is a next-generation open-source large language model optimized for complex coding, long-horizon tasks, and cybersecurity scenarios. It delivers significantly improved coding capabilities and agent performance compared with GLM-5.2.
GLM-5.2 is a significant update from Zhipu in the areas of open-source large models and AI coding.
GLM-5.1 (released April 2026), purpose-built for long-horizon autonomous tasks. Unlike traditional models optimized for short interactions, GLM-5.1 excels at maintaining goal alignment, reducing strategy drift, and delivering production-grade results over extended periods — up to 8 hours of continuous autonomous work on a single complex task. It represents a major leap in agentic engineering, shifting evaluation from single-turn intelligence to real-world sustained execution.
GLM-5 Turbo is a new model from Z.ai designed for fast inference and strong performance in agent-driven environments such as OpenClaw scenarios.
GLM-5 is Z.ai’s flagship open-source foundation model engineered for complex systems design and long-horizon agent workflows. Built for expert developers, it delivers production-grade performance on large-scale programming tasks, rivaling leading closed-source models. With advanced agentic planning, deep backend reasoning, and iterative self-correction, GLM-5 moves beyond code generation to full-system construction and autonomous execution.
