Background reasons for format conversion
The Gemini native API has access restrictions in China, and its interface specification is not compatible with the mainstream AI tool chain.OpenAI format has become the de facto standard in the industry, and AI development tools above 90% support this format by default.
Technology realization programme
The project implements a full OpenAI API emulation at the agent layer:
- Route mapping: /v1/models → return list of supported models
- Protocol Conversion: Converting OpenAI-formatted messages arrays to Gemini dialog structures
- Error Handling: Uniform return to OpenAI standard error code system
Developer Benefits
- toolchain compatible: Direct access to popular AI programming tools such as ChatBox, Cursor, etc.
- Zero cost migration: Existing OpenAI-based applications can be switched by simply modifying API endpoints
- unified commissioning: reuse OpenAI's SDK and test tools
- ecological integration: OpenAI integration module compatible with LangChain and other AI frameworks
Typical usage scenarios
Front-end developers can directly use the axios library to initiate requests according to the OpenAI documentation, while back-end services can use the official openai-node library, and all code can access the power of Gemini without any modification.
