GLM 5 Turbo vs GLM 5.1

GLM-5 Turbo is a new model by Z.ai built for fast inference and strong performance in agent-based environments like OpenClaw scenarios. It is heavily optimized for real-world agent workflows with long execution chains, offering better decomposition of complex instructions, improved tool use, scheduled and persistent execution, and greater stability throughout extended tasks.

GLM-5.1 represents a major advance in coding ability, with especially notable improvements in tackling long-horizon tasks. Unlike earlier models designed for interactions lasting only minutes, GLM-5.1 can operate independently and continuously on a single task for over 8 hours, autonomously planning, executing, and refining its work throughout the process, ultimately producing complete, engineering-grade results.
