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.
Enterprise-grade gateway to hundreds of AI models through one API
One endpoint and one API key reach models from OpenAI, Anthropic, Google DeepMind and other vendors, removing the need to maintain separate integrations.
Requests can be routed to the most suitable or most cost-effective model automatically, with balancing across providers for stability.
Text/LLM, image generation, video generation, audio (speech recognition and synthesis) and specialised decision APIs are all available through the same interface.
Detailed performance and spend statistics let teams monitor cost, latency and usage per model or per key.
Free / Open-sourceDelivers exceptional open-weight reasoning performance at very low cost, but lacks BigModel's broad enterprise multi-modal agent building suite.
