@Google_Google no reply?? explain to us why this is a valid reason to take $250 from us and not refund either if requested to cancel.
Similarly, the Pro Quota allows for 1h of work before everything is used up
I doubt you will get a concrete answer because this is borderline and answering your questions potentially opens them up to real liability.
I have two ultra accounts; on one I’m waiting 20 hours, on the other I have 4 hours left, but the limits are reached in 20 minutes. This is unfair and against the rules in both cases. How can they do this without providing any information?
I am reaching out because I have been facing repeated HTTP 503 trace errors on Antigravity for almost two weeks now, and I am not able to use the service properly.
I am currently paying for the Ultra plan, which costs more than $250 including tax, but my experience has been very poor. Some days, I am not even able to use Antigravity for 5–10 minutes before running into HTTP 503 errors again.
What makes this more frustrating is that my friend is using the $20 Google Pro plan and seems to be able to use the service more consistently than I can. Because of that, I am finding it hard to understand why the higher-tier plan is giving me worse access and reliability.
I have also noticed that when I check the model capacity, it shows that the limit refreshes in around 4 hours and 26 minutes. However, after only a few runs, the capacity bar drops quickly, and then I start getting errors again. I also have around 225,000 available AI credits, but those credits are not useful if I cannot actually use the service because of HTTP 503 trace errors.
I have already tried troubleshooting on my side. I removed the application completely, reinstalled it multiple times, tried different settings, refreshed the account, checked whether any settings or MCP servers were causing the issue, and even reset everything back to a clean setup. Nothing has fixed the problem.
At this point, I do not believe this is only a local setup issue on my side. It feels like there may be an account-level, capacity, or service-side issue affecting my access. I would appreciate it if someone could properly review my account and explain why this is happening.
Please let me know:
-
Why I am repeatedly getting HTTP 503 trace errors.
-
Whether my Ultra plan access is working correctly.
-
Why my available credits do not help when the service keeps failing.
-
Whether there is a fix or compensation for the time I have been unable to use the service properly.
I am paying for the highest plan because I need reliable access, but right now the service is not usable for my work. I would really appreciate a clear explanation and a proper fix.
same getting bad as worst

I keep getting HTTP 503 errors saying MODEL_CAPACITY_EXHAUSTED and “No capacity available for model claude-sonnet-4-6 on the server.”
This has been happening for almost two weeks, and I am barely able to use the service. Sometimes I try for only a few minutes and immediately get this error again. I am paying more than $250 for the Ultra plan, so it feels like I am paying for something I cannot actually use.
Can you please clarify if this issue is only affecting my account or if other users are also facing the same capacity problem? My friend on a lower plan seems to be able to use it more consistently, so I want to understand why my access is this limited.
Same here,
Its been happening for weeks.
Accoutn basically unusable.
Thhis didnt happen earlier.
I suspect it’s a per account issue. Basically I did something to make my account flagged.
Just a suspect though.
