As of my last update, Marvin does not natively support integration with Google GenAI (Gemini) for LLM models. However, Marvin is designed to be extendable, and it's possible to integrate external services like Google GenAI through custom development.
You might need to create a custom interface or adapter that allows Marvin to communicate with Google GenAI, similar to how other integrations are handled. This would involve using APIs provided by Google GenAI to send and receive data, and then processing this data within Marvin's framework.
If you have more specific questions about how to implement such an integration or need guidance on a particular aspect, feel free to ask!
