Sudden Cost Spike with gemini-3-flash-preview Despite Decreased Usage (April 2026)

Hi all,

Here’s today’s update.

2. Identifying affected users and implementing billing corrections

Status: In Progress

We’re making good progress here, I’m aiming to provide a more concrete update tomorrow.

3. Communicating the issue to the affected users
Status: Done

You should now have received a clear email of the issue and next steps, if not let me know.

4. Billing caps not respecting to the overcharged amount
Status: In Progress
We’ve reproduced the issue and are now investigating a fix.

In addition to this list, @depasquale I also looked at switching to pre-paid billing and sent you a note for your specific case. As a summary, this capability exists for US-based users, but we’ll be rolling this out more widely in the next month or so.
