Support for Vertex AI's Gemini Model

[wangleihr]

Hello,

I am a user of your chatbox project and I really appreciate the work you have done so far. I would like to suggest an enhancement that could greatly benefit users who are leveraging Google's Vertex AI platform.

Currently, the chatbox configuration includes a Gemini model, but it is not the one provided by Vertex AI. Specifically, the recently released Gemini Flash 2.0 model has shown outstanding performance in natural language processing and machine learning tasks. It would be fantastic if your chatbox could integrate support for Vertex AI's Gemini Flash 2.0 model, allowing users to take advantage of its advanced capabilities directly within the chatbox environment.

This integration could open up new possibilities for users who are looking to utilize state-of-the-art AI models in their applications. I believe this feature would enhance the versatility and appeal of your project.
