Why "[Billing Update] Gemini API usage tier updates and billing caps starting Apr 2026"

What you need to do

Manually verify and review your current usage to plan ahead and prevent service disruption when the new caps take effect:”

Service disruption? Caps?

Why can’t google cloud / ai just charge us and let us pay?

This “Gemini API usage tier updates and billing caps”, makes no sense.
What’s the use case?
What’s the reasoning?
How does this help developing on Gemini?

Recently I had to create a support ticket with Google Cloud in order get permission to add projects to our billing account. Adding projects = revenue for Google Cloud but only if they agree to let us pay them. Insane.

We don’t use AI studio at all, does this billing cap still apply to API usage through normal GCP Gemini APIs also?
