Antigravity is in preview and active development. Even though they accept payment for it, it is in no way production grade. And given the quality of their releases, the stability of their infrastructure, and the complete absence of support, I definitely would not feel comfortable saying Antigravity has “enterprise-level security and data protection”. There is nothing about this project that says “enterprise-level”.
I have to strongly disagree with you in terms of provided security guarantees. You are conflating the free individual preview with the paid business tiers.
We are paying (I do) for the Google Workspace AI Ultra for Business plan. Under Google’s own documentation, team usage is governed by Section 5 of the General Service Terms in Google Cloud’s enterprise terms of service. That legally guarantees a baseline of enterprise-level data protection and IP security.
A piece of software can be in technical ‘preview’ while still being wrapped in an ironclad, enterprise-grade security contract. Google is legally guaranteeing zero data harvesting of our code and binding the tool to their Cloud Enterprise Terms of Service (I am talking about Google Workspace AI Ultra for Business plan here). They are charging us top-tier prices for that exact IP protection and enterprise compliance. Therefore, expecting the infrastructure to actually be stable enough to use those secure features is completely justified.
Yeah, I’m completely on the same page with this.
I actually hadn’t seen 503 errors for a while, but lately, they’ve been popping up way too often.
Sure, hitting “retry” or asking the model to “continue” works as a temporary band-aid, but it’s really not a proper fix. Having the generation interrupted and forcing a “continue” mid-way totally breaks the workflow and definitely messes with the quality and consistency of the final output.
Right now, it’s getting to the point where I’m hitting a 503 almost every minute even when I retry, which makes getting any real work done practically impossible.
I strongly agree that there needs to be some kind of priority system. If we’re paying for the Enterprise/Ultra tier, shouldn’t we be getting guaranteed capacity or priority routing when the servers get slammed?
Absolutely there is no peak when it 24/24 I did try to use it every hour to see and there is always overload any hours day,night or early morning..
I have never had this on Ultra. I am using Opus 4.6 without any issue right now. How often does it happen to you?
Shouldn’t Ultra users get priority during peak hours? The constant 503 errors are making it completely impossible to get any work done right now.
This is very frustrating, it’s been going on for 2 months already. Until yesterday I was using antigravity version 1.19.6 because this problem didn’t occur in that older version, but now Google has deactivated that version and it’s unbearable.
And it’s not a matter of maximum capacity because I log out of my Google Workplace professional account and log into my personal account and mysteriously there is no more “capacity exhausted” message.
yes I am completely on the same page with this….
I am beyond frustrated. I’ve been paying for the Ultra Tier specifically to avoid service interruptions, yet for the past 48 hours, my workflow in Antigravity has been completely paralyzed.
I keep getting hit with HTTP 503 Service Unavailable and MODEL_CAPACITY_EXHAUSTED for claude-sonnet-4-6. My logs show the server (ESF) is dropping requests after nearly a minute of “working” time.
Technical details of the latest failure:
-
Trajectory ID: 73ccf327-79a3-4fa8-b4f2-a3b4d517
-
TraceID: 0x5044f7139b2
-
Error: No capacity available for model claude-sonnet-4-6 on the server.
Why am I paying premium prices for a service that treats me like a free-tier user during peak hours? This downtime is costing me significant time and money. At roughly $10/day for this subscription, I expect a stable environment, not a “High Traffic” lottery.
Consider this my final notice: this is the last month I am paying for this subscription unless Google fixes the capacity issues immediately. Furthermore, I believe a compensation/refund for these days of total service failure is the bare minimum a tech giant should provide to its professional users.
Fix your infrastructure.
