Zhipu AI's open platform for GLM large models, multimodal APIs, and agent building
Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
Build tool-using agents and expose or consume MCP services to connect models to external systems.
Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
Tune models on your data and prototype prompts interactively in the browser before shipping.

Plan, schedule and analyse social media from one calendar
Plan posts to Facebook, Instagram, LinkedIn, Pinterest, VK and Google Business Profile on one visual calendar, then automate publishing.
Queue large volumes of posts — with graphics and video — in a single upload to save time on recurring campaigns.
