Feature Request: Add Support for Google Gemini API

[ovftank]

I am writing to request the addition of support for the Google Gemini API as an alternative to the current OpenAI integration. While OpenAI provides excellent services, the associated costs can be quite high for some projects and users. Integrating Google Gemini would provide a more cost-effective option and enhance the flexibility of our application.

Benefits

1. Cost Efficiency: Google Gemini offers a pricing model that might be more affordable for certain users and projects, allowing us to cater to a wider audience.
2. Flexibility: Users can choose the AI service that best fits their needs, whether that be based on pricing, performance, or other factors.

Proposal

Configuration Options: Add settings in the application to allow users to select between OpenAI and Google Gemini, including any necessary API keys and configuration parameters.

Thank you for considering this feature request. I believe it will greatly enhance the utility and appeal of our application.
