I am writing to report a bug I have been experiencing since the new AI credits system was implemented. I have been a Pro user from September of last year, and since I am currently working on projects with tight deadlines, I respectfully request immediate assistance.
I am unable to use my remaining 921 AI credits after my baseline quota is exhausted. I initially had 1,000 AI credits. The system automatically used 79 of them to finish a few completions when my baseline quota ran out. However, when I try to continue using the Pro models, the “send message” button doesn’t get enabled and, when hovering the model selected, I am shown the error message stating that I need “at least 50 AI credits” —even though my actual balance is well over that amount. The system seems to be completely ignoring my available credits.
Note: I am running the last version of the software, and before this update, I was being shown that I needed “at least undefined AI credits,” which suggests this is a software bug rather than a subscription-related issue.
I understand the new system rollout has been complex globally. However, this bug forced me to pay for an alternative service (Claude Code) just to meet my deadlines. As my account logs show, I haven’t been able to “intentionally” use a single credit since the update. Once the technical issues are resolved, I respectfully ask that you consider a proportional in-kind compensation for the inconveniences.
Additional Feedback:
I noticed that the credit consumption seems unusually high. 79 credits were deducted just to finish fewer than 4 completions that had already started under the baseline quota.
The new baseline quota is significantly low, making it difficult to use the service effectively. While my main concern right now is the bug, I highly ask for a deep reviewing of the quotas criteria.
My priority right now is to gain access to my credits. Could you please look into this bug?
i feel your pain but there are some lowkey mechanics here you probably didnt realize are wrecking your experience. the reason you are stuck at 921 credits with a disabled button is a classic pre-flight validation gate bug. basically before you even hit send the app does a stealth check to see if you can afford the max cost of the prompt plus your huge context history. because your app was throwing that undefined error before it means the link between your windows client and the credit server is straight up dead. even though the ui now says 50 credits the code behind it is still pulling a null value so it thinks you are broke and stays grayed out as a fail-safe. also that 79 credit drain for just 4 completions is actually a context tax. since your baseline hit zero mid-task the system had to re-process your entire project file and thread history using paid credits just to get the model back up to speed to finish the thought. you arent just paying for the output you are getting charged for the re-read of everything you already did. its not a subscription fail its a front-end logic loop where the gatekeeper cant see your wallet so it wont let you through the door. turn down your max output tokens to the floor and see if that force-enables the button otherwise your client is just shouting into a void.
Thanks for the insight into the backend mechanics.
Regarding your suggestion to turn down the max output tokens to the floor—I’m hitting a wall because Antigravity doesn’t expose this parameter anywhere in the UI or settings.
Do you know of a specific, undocumented method, a local config file, or a CLI flag to actually override this?
The bug I reported is actively getting worse. Not only is the UI still completely blocking me from intentionally using my AI credits, but my account is now being drained in the background.
My balance inexplicably dropped from 921 to 424 AI credits. I checked my credit history today and found these automated deductions:
Apr 2, 2026, 9:00:00 PM: Google Antigravity hourly activity -249
Apr 2, 2026, 8:00:00 PM: Google Antigravity hourly activity -248
This makes zero sense. The UI still gives me the “insufficient credits” error blocking any paid usage, so I have strictly been using the baseline quota for Antigravity when available, and doing all my heavy work on Claude Code (which I had to pay for just to meet my deadlines due to this bug).
How is the system charging me nearly 500 credits for “hourly activity” when I am completely locked out of using them? This has gone from a UI bug to an active billing/balance issue.
Notice that this happened after I published my first post here, which makes me even thing someone tested something on the backend and accidentally drained my credits.
Can someone from Antigravity please escalate this immediately?
