GLM
GLM is Z.ai’s family of language, vision, video, and agent models, available through a web app and developer API.

In inglese
GLM supports chat, coding, long-horizon tasks, tool use, structured output, multimodal understanding, and agent workflows. Z.ai presents GLM-5.3 as its latest flagship model for complex engineering and extended agent tasks.
Users can access GLM through Z.ai’s web experience or API, with documentation for language, vision, video, and agent products. The API uses usage-based pricing, but the official pricing page did not expose specific tier amounts during this review.
