Google Cloud Console's billing console for Vertex is so poor. I'm trying to figure out how much i spent on which models and I still cannot for the life of me figure it out. I'm assuming the only way to do it is to use the gemini billing assistant chatbot, but that requires me to turn on another api permission.

I still don't understand the distinction between Gemini and Vertex AI apis. It's like Logan K heard the criticisms about the API and helped push to split Gemini from the broader Google API ecosystem but it's only created more confusion, for me at least.
