English | Chinese

Most OpenAI clients do not support Azure OpenAI Service, but the application and card binding of Azure OpenAI Service are very simple, and there is also a free credit limit. This script uses the free Cloudflare Worker as a proxy, allowing OpenAI-enabled clients to use Azure OpenAI Service directly.

Supported models:

• GPT-3
• GPT-4
• DALL-E-3

Adding model subclasses is very easy, refer to the following instructions for use
