GLM-5 moves Z.ai’s line into a new foundation class with 744B total parameters, 40B active parameters, and 200K tokens of context. Compared with GLM-4.7, Z.ai describes the larger base and stable tool use across many steps as a generational change. The weights remain openly available.

Z.ai provides the checkpoint through an API and open weights. GLM-5.1 is the direct follow-up and focuses on greater stability for long tasks.
