Is it really that confusing? Gemini is the equivalent of ChatGPT; AI Studio is for advanced users that want to control e.g. temperature; Vertex AI is the GCP integrated API; Notebook LLM is basically personal RAG; and Jules is a developer agent.
Vertex AI also has an AI studio. All of these products also have rag like abilities. You can add documents to Gemini and ask it questions. When would an end user switch to notebooks to do this?
And not that there isn’t a level of knowledge you can gain to answer these questions, it’s just not clear.
Many of these are not even remotely similar.
