What Z.ai (Zhipu AI) does
Z.ai (brand name for Zhipu AI) is an AI platform company that develops the GLM family of foundation models and packages them into hosted “model + agent” products for developers and end users. The company’s commercial stack is centered on a MaaS (Model-as-a-Service) platform, where GLM models are deployed behind APIs and user-facing assistants/agents, including agent workflows designed to “execute” tasks rather than only answer questions (e.g., AutoGLM and its variants).
