This project provides an API endpoint that mimics the OpenAI GPT-3.5-Turbo API, leveraging a login-free ChatGPT web interface. It's designed for developers and users seeking to integrate GPT-3.5 capabilities into their applications without requiring API keys or incurring costs, offering a free alternative for experimentation and development.

How It Works

The service acts as a proxy, intercepting requests intended for the OpenAI API and forwarding them to a backend that utilizes the login-free ChatGPT web interface. It specifically targets the gpt-3.5-turbo-0125 model and is based on DuckDuckGo's infrastructure. This approach bypasses the need for official API access, enabling free usage.
