Strange project in my google AI Cloud

I have a Google cloud account.

Probably I opened accidentally because I am a researcher that is doing some tests in developing through Google AI Studio.

I never linked any billing account apart from my Google AI Pro subscription.

Today I checked and in Google Cloud I see this project

Can someone help me to understand what is ? Is there any risk that I will receive some charges.

Additionally if in Google AI Studio I select Gemini 4 Argon even without any API Key linked but selecting only “Google AI Pro Subscription” as quota the Gemini 4 Argon is available and works. Is this normal ?

From my understanding Argon has no free allowance you pay from the first
I asked one of my apps for a comparison I did mean for the whole app.
What i got was just to answer that question sending everything up and getting it back.
Here is what it came up with. My initial thoughts are Yikes!

Yess very strange

No API Key seems created or linked but from today all paid model are usable

Additionally I saw this suspicious project on Google Cloud that results created on 28/09/2026 and linked to GoogleDeepMind billing account managed by Google

I explain better with these three screenshots.

AI Studio is charged only on AI PRO subscription quota or on a free tier.

I don’t have any personal billing account

However I see in my projects (Google Cloud) a project linked to billing account managed by Google Deep Mind. I am very scared . Can someone help me ?
