gemini API support

[hrez]

Hi,
It would be nice to support Google's gemini API directly.
Relevant SDK is https://github.com/google/generative-ai-go

Thanks.

Thank you. To support other LLMs, we may need to implement an abstraction layer for the LLM API. Integrate a tool like langchain-go could be a viable solution. I'll look into it further.
