I am an AI Pro subscriber (paid), but I only have access to Anthropic version 4.6 models instead of version 5.5, and I still don’t have access to Argon.
Hi @Mario_Laserna,
Welcome to the Forum,
Based on the models you are seeing—specifically having access to Claude 4.6 but not Claude 5.5 or Gemini 4 Argon—it appears that your account is currently being recognized by the system as a Google AI Pro (Trial) subscription rather than a fully paid subscription.
According to the Models, Claude 5.5 and Gemini 4 Argon are reserved specifically for non-trial paid plans.
If you have already paid and should no longer be on a trial, there might be a sync issue with your billing status. The documentation advises that to switch from a trial to a paid Google AI Pro plan, you should Submit an upgrade request.
Hi @chunduriv , I have been a paid user for several months. In fact, I saw the 5.5 models for a few days, but after one of the recent updates to the Antigravity desktop app, they disappeared.
Hi @Mario_Laserna,
Thank you for the clarification. Since the issue started after a recent update, could you please check and upgrade to the latest version of the Antigravity desktop app/CLI?
Additionally, please try clearing the app cache to see if that forces your account entitlements to refresh.
If you are still seeing this issue with your account sync after taking those steps, please submit your situation through the support form linked in my previous response so the team can look into your account directly.
Hello, I have an active, paid Google AI Pro subscription (5 TB) since August 20, 2026. My Antigravity CLI is up to date (version 1.4.0), but I can only access Claude Sonnet 4.6 and Claude Opus 4.6. Gemini 4 Argon and Claude 5.5 are unavailable.
Could you please check whether my account is incorrectly being recognized as a Google AI Pro Trial subscriber and help synchronize my subscription entitlement?
Thank you.
