About this model
GLM-5.1 delivers a major leap in coding capability, with particularly significant gains in handling long-horizon tasks. Unlike previous models built around minute-level interactions, GLM-5.1 can work independently and continuously on complex problems, making it well-suited for agentic workflows and sustained coding sessions.
