so by looking at the image you put there - where you went to
https://aistudio.google.com/rate-limit
i do see a toggle there for “All Models” and also theres a dropdown for "Project” - that’d be my gut instinct, is toggle “All Models” ON, and then check every dropdown to see if it pops up there
its absolutely frustrating trying to navigate many of these things, the google workspace admin, the google one manager, the google aistudio and google cloud portals - its all incredibly overwhelming!
The “Google Assistant” haha its so silly, it tries so hard, little faqbot ragbot haha
i can’t do it i’ve tried and i last like 20 seconds until i’m like clicking that GEMINI button in the title bar on chrome to pop open the browser sidebar
but still, i use the aimode.google.com assistant most often.
So, doing some searching, it looks like I was close.
First - make sure that Google Account in your browser is the one you’re using in VS Code!
In VS Code :
Open Settings, and just type in the search “GEMINI”. What you want there is the PROJECT ID.
That is the project you would want to check https://aistudio.google.com/rate-limit for
Toggle All Models, Click the Projects dropdown, and select the one that matches PROJECT ID.
And if you wanted to check it on Cloud
https://console.cloud.google.com/iam-admin/quotas
You’d want to click on the top left where it says Google Cloud - to the right of it in a box.
Thats the Project Picker, so you’d check for your project there, so same thing, match the id.
You SHOULD be able to just click the header “Current Usage Percentage” once or twice and have it sort so you see like a bar or something.
But also, you can just scroll down and try to find it by scrolling and looking.
There might be a lot - so you can use the filter to refine that list there.
You’ll see “Enter Property Name Or Value” thats your filter search!
So you’d wanna check first for GEMINI just type it in there.
And then clear that out, just jam backspace in that same filter search area.
Next check would be for “Generative” (short for Generative AI).
Now theres another way to check stuff which is start at this link
https://aistudio.google.com/projects``
So if your VS Code project shows up here, you can just click the Bars on the right of it to get the usage page, the dollar sign to check your spending page.
If you don’t see it, on the top right theres an “Import Projects” button.
If you see that project there, you don’t have to import it - you know its in the Cloud, not AI Studio!
Haha that was an adventure digging around these things - i never use it because its so intimidating, i’ll be writing code with aimode.google.com and just assembling it piece by piece even though all that stuff is there haha. Sometimes Gemini AI is too smart for their own good! I always try to remember, as an LLM Gemini is just like using Command Line Interface commands to do stuff at 300mph while we have to use the Graphic User Interface at like 2.5mph walking speed 
Anyways - i don’t wanna overwhelm you too - but that should help you check your quotas! Let me know how it goes, always glad to help!
