Title: Google AI Pro Subscription Not Showing in Antigravity IDE

[Saloni_Madhekar]

My Google AI Pro subscription is visible on my mobile phone, but the subscription benefits or expected Gemini model options are not appearing in my Antigravity IDE on Windows.

I have already checked my Google account and tried resetting the Antigravity onboarding process, but the issue remains unresolved.

Could you please clarify whether my subscription is eligible for the Gemini models available in Antigravity and help me resolve this issue?

Thank you.

Hi @Saloni_Madhekar,

Thank you for reaching out.

Since you have already verified your Google Account and tried resetting onboarding in Antigravity IDE, here are the two reasons why expected Gemini models or Pro benefits may not appear in your setup:

1. Gemini Model Support in Standalone Antigravity IDE (v2.5.5) vs. Antigravity App (v2.24.0):
   • In the standalone Antigravity IDE (v2.5.5), Gemini 3.8 Flash (Low, Medium, and High thinking levels) is the supported Gemini model across all plans (Choose a model).
   • Gemini 4 Argon is supported in the Antigravity App (v2.24.0), Antigravity CLI (v1.4.2), and Antigravity IDE extensions (VS Code, Visual Studio, JetBrains, Zed, and Xcode), and is not available in the standalone Antigravity IDE.
2. Mobile Carrier, Device, or Trial Subscriptions (Google AI Pro (Trial)):
   • If the Google AI Pro plan visible on your mobile phone is a free trial, student offer, device promotion, or mobile carrier bundle (such as Jio or Verizon), it is provisioned in Antigravity under the Google AI Pro (Trial) tier (Plans).
   • Google AI Pro (Trial) includes Gemini 3.8 Flash, GPT-OSS-120b, and Claude 4.6 (through November 2, 2026), while Gemini 4 Argon and Claude Sonnet 5.5 / Opus 5.5 (thinking) require a direct, non-trial paid Google AI Pro or Google AI Ultra subscription (How do I upgrade to a paid Google AI plan?).
3. If You Have a Direct Paid Subscription and Your Plan Tier Still Does Not Sync:
   • Check https://policies.google.com/terms (country association form) and pay.google.com to ensure your Google Account country and Google Play / Google One billing profile match a supported country/region, and test signing in with the Antigravity App (v2.24.0) (Download).
