I believe so. If you do not already have a Google Cloud account, you will need one so you can make a project, and thus get your Cloud project ID. I thought you needed one to access the Gemini API, but I guess I’m wrong there.
Google has a big ecosystem, so don’t fret. We’re all figuring out what goes where right now.
On the bright side, Google Cloud stuff is actually really easy to navigate and set up. It’s not like AWS. It is far more beginner-friendly and no-nonsense.
