Gemini Code Assist Tenant Billing Account linked to a project in my cloud console - no billing set up

Hello, I’ve been playing with gemini-cli and the gemini-app as part of the google one AI pro program.

I have not set up any billing in the cloud console because I’m worried about accidentally running up a high bill from gemini by accident. However, when I go into the console I can see a project I don’t recognise formed of 3 random words. When I click into it via billing it is linked to a billing account called “Gemini Code Assist Tenant Billing Account global4”

Does anyone know what this account is? Google only have my payment details via Google One. I have not (to my knowledge) set up a cloud billing account.

When I use gemini-cli I log in with my gmail.com account.

Am I at risk of running up a bill? I can’t see any billing info in the console as it says I don’t have permissions to view.

Thanks
