Credits were working fine for the last two days. Baseline would run out, credits kicked in, I kept working. Exactly how it’s supposed to work. My activity log shows normal deductions from Mar 24-26 — anywhere from 10 to 1,282 credits per hour depending on the session.
This morning, baseline ran out again. But instead of switching to credits, I got this:
“You need at least undefined AI Credits to send messages.”
Undefined. That’s a bug in the code.
Meanwhile, my Settings page shows 39,198 credits available. The system can see them. It just won’t use them.
So I’m paying $250/month plus spent another $200 for a 20K credit top-up on top of that. I have nearly 40K credits sitting there. And the system is telling me to buy more.
Also tried filing this through the in-app Report Issue tool. THAT THREW AN ERROR TOO!
tbh, don’t buy credits, their billing is completely opaque and has major issues. You’d be better off spending that $200 on Claude or Codex—at least they are much more transparent than Google.
Spot on. The 5-tier metric is fundamentally anti-developer. We build applications based on hard limits and precise token math, not vague percentages. Hiding the raw numbers feels less like an ‘upgrade’ and more like a strategy to keep paying users in the dark. We need absolute numbers back.
Thank you for bringing these concerns to our attention to the quota issue. Please be assured that I have shared your feedback with our internal team for further review.
We appreciate your continued patience as we work to enhance the Antigravity experience.
@Abhijit_Pramanik I’ve always believed that other users were just expecting too much from the free and pro tiers. But the consistent reduction in quotas with no clear communication is destroying trust from your user base.
I logged in this morning and asked 2 requests - one was to fix a slight race/timing issue and the second was to review a dialogue pop up not working as expected. No implementation and then baseline quota reached. This is now unusable. As someone paying for Ultra, this is just unacceptable
fundamentally anti-developer. That line issss a stretch. I’m with you guys on the quotoss, but I dont think Google Is doing this on purpose. So many AI tools have been FREEE for MONTHS but pulling the rug on ultra users is a bad look. BUT
I’m glad someone on here is having this feedback to take back to the team for accountability.
That’s what I’m seeing. This product had such potential but clearly shouldn’t have been released AND then so poorly supported. Tech companies tend to know these moves destroy community. They can absorb that on consumer side for a while. Anthropic might charge a premium, but the product seems to be on a different level.
Same issue here. Ultra subscriber, March 27, 2026.
Today at around 16:30 my 5-hour baseline window ran out. My Settings page clearly showed 21,000 AI Credits available. Instead of switching to credits as it should, Antigravity threw this:
“You need at least undefined AI credits to send messages.”
“Undefined.” That is an uninitialized JavaScript variable that Google shipped to production. The system can see my credits. It just cannot use them.
The consequence: 2 full hours of freelance work lost during an active client deadline. Not “inconvenient.” Lost. Gone. Billable hours I cannot recover.
I subscribed to Ultra at end of February. My first billing cycle ran normally. I renewed on March 25 into a second cycle — and by day 1, the service had already failed completely. Zero communication, zero changelog, zero email from Google. Both the baseline quota AND the credit fallback broke at the same time.
To be unambiguous: I am not asking for a fix or an apology. I am requesting a full refund for this billing cycle. If Google cannot deliver a basic “credits work when baseline runs out” feature — a feature that worked for 23 days and then silently broke — they are not delivering the service I paid for.
I will be filing formally through Google One support. If that fails, bank chargeback and an consumer authority complaint follow.
Yes, and as other posts have noted as well, I too am now experiencing DRAMATICALLY reduced Opus use despite paying this huge fee for Ultra! It really appears that Google is deliberately ruining what could be a good product. Once VSC gets better Opus cache management, I’m going back to it (unless there’s a better alternative?). Repo grounding and stability were better than this hack-job Google has turned Antigravity into!
