Gemini-OpenAI-Proxy

Gemini-OpenAI-Proxy is a proxy software. It is designed to convert OpenAI API protocol calls into Google Gemini Pro protocol, so that software using OpenAI protocol can use Gemini Pro model without perception.

If you're interested in using Google Gemini but don't want to modify your software, Gemini-OpenAI-Proxy is a great option. It allows you to easily integrate the powerful features of Google Gemini without having to do any complex development work.
