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.

No-code AI customer service agents for web, WhatsApp, Instagram, Telegram and Messenger
Run one AI agent across your website, WhatsApp, Instagram, Telegram, and Messenger, and manage every conversation from a single unified inbox.
Sync your website, docs, and help center so the agent answers from current information, with weekly or daily auto-resync on paid plans.
When the AI cannot resolve an issue, it hands the conversation to your team and summarizes it first so agents have instant context.
Let the agent perform real tasks mid-conversation and automate multi-step processes triggered by conversation, contact, or action events.
