To use Gemini i don't need to set GCP creds project IDs in LiteLLM/DSPy but in baml it requires me to set it. why is that?

I remember the authentication part was kinda complicated, doesn't it work with the API key only?

ah instead of usinv "vertex-ai" if i use "google-ai" it allows me to pass just the GEMINI_API_KEY.

vertex ai requires to create a project and login through cli. Those are two different services -- confusing
