GLM 5.2
GLM-5.2 is Z.AI's latest flagship model, meticulously engineered for long-horizon autonomous tasks. Capable of working continuously on a single assignment for up to 8 hours, it autonomously manages the entire workflow—from initial planning and execution to iterative optimization and the delivery of production-grade results. With coding and agentic capabilities that rival leading proprietary frontier models, it excels particularly in sustained execution, complex engineering optimization, and real-world development scenarios. Its context window has been expanded from 200K to 1M tokens, making it an ideal foundational model for powering advanced autonomous agents and long-horizon coding assistants.
GLM-5.1
GLM-5.1 is Z.AI's latest flagship model, meticulously engineered for long-horizon autonomous tasks. Capable of working continuously on a single assignment for up to 8 hours, it autonomously manages the entire workflow—from initial planning and execution to iterative optimization and the delivery of production-grade results. While its general capabilities and coding proficiency are on par with Claude Opus 4.6, GLM-5.1 excels particularly in sustained execution, complex engineering optimization, and real-world development scenarios. This makes it the ideal foundational model for powering advanced autonomous agents and long-horizon coding assistants.
