Antigravity Pro subscription not showing third party models

I have a Pro subscription, but Claude 5.5 Sonnet and Opus are not showing up for me. I’m also receiving a message saying that these models will no longer be available under my subscription plan.

Isn’t the Pro plan supposed to include access to these models?

Hi @Lucas_Martins,

Welcome to the Forum,

Under Antigravity’s Models Policy third party models are only available on directly billed (non-trial) Google AI Pro and Ultra subscriptions. If your Google AI Pro plan is currently on an introductory trial, device promo, or partner benefit, it is classified as a promotional plan and does not include Claude 5.5 access.

To retain access to third-party models after that date, you will need to upgrade to a directly billed Google AI Pro or Ultra plan via Google One.

(Note: All Gemini models remain fully available on your current plan)

So basically anyone on the Verizon plan will be locked out of these features for the first 6 months of their plan. That’s lame. Guess I will be going back to Claude.

Hi @Tethgar,

Welcome to the Forum,

I completely understand the frustration. To clarify, you aren’t strictly locked out for the entire 6 months, but you do have to choose between keeping the promotional Verizon benefit or getting access to the third-party models right now.
