Well, originally what was wrong was that non-vertex customers got much lower limits and about twice the time to first token as vertex customers. So I used a vertex key setup. However, the cli had me in auth hell trying to connect up with vertex. Like literal spinning. So, thank you. I wiped my vertex environment variables and upped my gemini key level, and it mostly works now.

Glad to help! Also, in case it matters, the old "google-generativeai" libraries have now been replaced with "google-genai".
