One OpenAI-compatible endpoint for OpenAI, Claude and Gemini models
Send requests in the familiar chat-completions format to a single base URL, so existing OpenAI SDKs and wrappers work with minimal edits.
Reach OpenAI, Claude and Gemini models from the same credentials instead of juggling three separate accounts and billing setups.
Swapping providers usually means changing a base URL and a model name rather than rewriting application code.
Choose the model that best fits a task's price and quality needs, helping keep inference spend under control.
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.
