[Entitlement Desync] Paid annual Google AI Pro user — Gemini 4 Hydrogen & Argon marked "Unavailable" in Antigravity App

Hello Antigravity Support & Engineering Team,

I am experiencing a backend entitlement desync on my active paid annual Google AI Pro account. Although my subscription is fully paid and active, Google Antigravity appears to be treating my account as a Trial/non-paid tier.

### 1. Account & Subscription Details

- **Plan:** Active Paid Annual Google AI Pro (billed directly to my personal credit card; not a free trial, family-shared plan, or promotional offer).

- **Gemini Web Status:** `Gemini 4 Hydrogen` is available and works normally on `gemini.google.com`.

### 2. Issue Symptoms in Antigravity App

- **Models & Usage Page:** Correctly displays `Your Plan: Google AI Pro` with active Weekly and 5-Hour quota remaining.

- **Model Selector:** Both `Gemini 4 Hydrogen` and `Gemini 4 Argon` are grayed out as `Unavailable` (the info tooltip states: *“currently available to paid Pro and Ultra subscribers”*).

- **Claude Entitlement Signal:** Only `Claude Sonnet 4.6 (Thinking)` and `Claude Opus 4.6 (Thinking)` are listed instead of the Claude 5.5 models.

### 3. Troubleshooting Already Completed

- Downloaded and installed the latest **Antigravity App** (in addition to testing the standalone IDE).

- Executed `Antigravity: Reset Onboarding` via the Command Palette (`Ctrl+Shift+P`) and signed back in multiple times.

- Verified that AI credit overages remain disabled.

### 4. Request

Since I am on a paid annual subscription, please do not ask me to cancel and repurchase the plan. Could a team member please inspect my account’s backend entitlement flags and manually resync my **Paid Google AI Pro** status so `Gemini 4 Hydrogen` and `Gemini 4 Argon` are unlocked?

Hi @YSG0531,

Welcome to the Forum,

Thank you for sharing those details.

Please check the following:

  • Age & Terms of Service Region: In a desktop browser signed into the same personal @gmail.com account, confirm that 18+ age verification is completed at Google Account Age Verification and that the country shown on the Google Terms of Service page is in a supported region.
  • Refresh Quota State in v2.31.2: Confirm you are on Antigravity App v2.31.2 (Changelog), open Settings > Models (Models & Usage), and click the circular Refresh icon next to the heading.

Since your screenshot shows the Gemini mobile app, please reply with a screenshot of your Models & Usage page in Antigravity Settings and let us know whether this account previously held a student, device, or free-trial promotion before switching to the annual plan so we can investigate further.

Hi, I’m experiencing the same issue with my Google Antigravity account.

I currently have two active Google AI Pro accounts, both with regular Pro subscriptions (not student offers or trials). However, they have different model availability despite being used in the same Antigravity App installation.

Affected account:

  • Antigravity correctly displays “Your Plan: Google AI Pro.”

  • Gemini 4 Argon and Gemini 4 Hydrogen are marked as “Unavailable.”

  • Only Claude Sonnet 4.6 and Claude Opus 4.6 are available.

Second Google AI Pro account:

  • Gemini 4 Argon and Gemini 4 Hydrogen are available.

  • Claude Sonnet 5.5 and Claude Opus 5.5 are also available.

I have already verified my age and confirmed that my Google Terms of Service country version is the Philippines. I also tried resetting Antigravity onboarding, but the issue persists.

Since both accounts use the same application and subscription tier, I suspect this may be an account-specific entitlement synchronization issue.

Could the Antigravity team please investigate whether the affected account’s model entitlements are configured correctly?

Thank you!
