Although the ChatGPT service (based on the gpt-3.5-turbo model) is currently freely accessible without logging in, accessing it via an API interface incurs a charge. This project converts the free ChatGPT web service into a complimentary ChatGPT API, with the interface response consistent with the official one and supports Docker deployment. It is important to note that the server used for deployment should be in a country or region where the OpenAI service is supported.
