零一万物开放平台

What this platform is

The Zero One Everything open platform, from 01.AI, is the developer entry point for the Yi series of models. It supports dialogue, text and code generation, tool and function calling, streaming output and long context processing, with API key management, usage and billing queries, SDKs and documentation.

What you can do with it

• Call Yi models for dialogue and generation
• Use tool calling to connect systems
• Handle long documents in one request
• Stream responses for interactive use
• Track usage and manage keys centrally

Who it is for

• Developers building Chinese-language products
• Enterprises needing a domestic model API
• Teams integrating long-document processing

What to watch out for

• Access, documentation and support are oriented to the Chinese market
• Data submitted to the API is processed in that jurisdiction, which matters for cross-border use
• Long context and capability claims should be measured against your own documents
• Model generations change, so pin the version your application depends on
