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 OpenAI-compatible API for 200+ AI models
RouterBase is a drop-in replacement for the OpenAI SDK: change the base URL and route to 200+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and xAI.
Auto-select the best provider per request by price, latency, or availability, and fall back to another provider in milliseconds when one fails.
Pay against a single balance and get one invoice across every provider instead of juggling a dozen accounts.
Track spend by model, API key, or project, export to CSV, or query via the API, and set per-key monthly spend caps.
