GLM-5.1

GLM-5.1 is an iteration on Zhipu AI's GLM-5 flagship, refining reasoning, coding, and tool-use behavior across the bilingual GLM line. It targets the same agentic and long-context workloads as GLM-5 with incremental improvements in instruction following and structured output reliability. A solid choice when you need GLM-tier quality with the latest tuning available.
