Today I got an email that said my project went WAY over budget.
I looked at my dashboard and then my billing and sure enough there is a huge spike in one thing:
‘Generate content cached content storage token hours gemini 2.5 pro’
I have been meticulously tracking my usage costs and I’m nowhere near what it’s saying I am. I do not orphan caches or any of that and my TTLs are very short.
Thank you for reaching out. I’m sorry to hear about the unexpected costs you’ve encountered. For any issues related to billing, unexpected charges or payments the Cloud Billing support team is the best group to assist you. You can contact them directly here: Get Cloud Billing support | Support Documentation | Google Cloud
I have contacted them and they have said they sent it to some internal team. I haven’t heard anything and continue to see increase in charges even with my API keys deleted.
