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.
One API for AI image, video, and audio generation
One endpoint and one request schema across every supported image, video, and audio model, so you integrate once and switch models through a single parameter.
Generated outputs come back as durable links that stay available, removing the need to build and maintain your own storage pipeline.
Models are exposed through official protocols including OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, and Google Interactions.
Built-in MCP tools, reusable Agent Skills, and an llms.txt index let coding agents and assistants discover and call HiAPI on their own.
