GoogleCloudPlatform/generative-ai ? reverse-engineered prompt

I want to create a project with a bunch of examples for using Google's Generative AI, especially with Gemini on Vertex AI. Please create a collection of sample notebooks that show me how to do a variety of things. I'd like to see how to get started with the latest Gemini models, including some starter examples, function calling, and maybe a few sample apps.

It should also cover how to build my own search engine using Vertex AI Search and Retrieval Augmented Generation (RAG). I'm also really interested in the creative side, so please include examples for vision models like Imagen for creating and editing images, plus some demos for audio and speech processing. Organize everything into clear folders by topic, and make sure to include instructions on how to set up my Google Cloud environment to run everything.
