Google AI Ultra 20x Family members appear to share Antigravity quotas. Is this intended?

Google Antigravity

Hello,

I am a Google AI Ultra subscriber and have confirmed that Antigravity usage quotas appear to be shared across family members in my Google Family Group.

When one family member heavily uses Antigravity, other family members encounter quota limits as well. Based on our testing, the quota does not appear to be independent for each user.

My question is:

Is this the intended behavior, or is this a bug?

The Google AI Ultra plan includes Family Sharing, which naturally leads many users to expect that each family member would receive their own usage quota.

If quota sharing across the entire family group is intentional, could Google provide official documentation explaining:

  1. Which quotas are shared across family members?

  2. Which quotas are allocated per individual user?

  3. How Antigravity quotas are calculated within a Family plan?

I have seen multiple users reporting similar experiences, but I have not found clear official documentation on this topic.

I can confirm the same on my Google AI Pro Family account, both kids used the same time and drained limits in 30 minutes.

Yes. These are shared. It previously used to be independent, but people kept making 5 accounts to 5x their quota, so they made it shared.

Just an unrelated tip, if you use Gemini 3.5 Flash (Med), instead of Opus 4.6 (Thinking), you will be able to send many more messages. Opus is very heavy and thus consume a lot more quota for not much benefit on small tasks

opus 4.6 just exhausted my token in 1 prompt

I purchased the Google AI Ultra 20X Family plan for approximately 7,500 THB (~$230 USD), which is Googleā€™s highest-tier AI subscription, not a standard or entry-level plan.

Given the premium price of this subscription, I expected each family member to receive their own independent Antigravity usage quota. However, based on our testing, the quota appears to be shared across all members in the Family Group.

Could Google clarify whether this behavior is intended or if it is a bug?

This is intended. You can consider that they sold you a single account, and if you can make 5 accounts, or share them with 5 people, it would actually increase their expenses beyond the services.

Therefore, the compute heavy services (like Gemini) are shared + their own free plan
