GLM 5.2

GLM 5.2 is a 355B text-only model with a 1M context window and an intelligence index of 26. It handles long text and structured output, and some pipelines are already tuned to this checkpoint. GLM 5.3 is the better default for tool calling: same context window, image input, and an intelligence index of 32. Keep 5.2 when you need the older text-only behavior.
