Support for Gemini and Ollama

[cornusandu]

I would love to see this have support for Gemini and Ollama -- a lot of us use the Gemini API because it's free, and some of us use Ollama because it's free and because of privacy reasons, so allowing us to use these two would be great. I could (and would) make a fork for this, but I write horrendous code and can't understand yours, but please contact me if you want a fork for this and I'll... try.
