Hi @Ali_ozirk,

Thank you for reaching out and sharing the screenshot.

Here is why you are seeing those notices in your model selector and how to resolve them:

- **1. Why Gemini 4 Argon & Claude 5.5 Show as Unavailable (Trial or Promotional Plan vs. Paid Plan):** In your screenshot, the notice (_“Opus 5.5 is now available on paid Pro and Ultra plans. Third-party model access will no longer be available on your current plan starting on November 2, 2026”_) indicates that your Google AI Pro membership is currently active on a **free trial, device promotion, or partner bundle**. [Gemini 4 Argon](https://antigravity.google/docs/models/#reasoning-model), **Claude Sonnet 5.5 (thinking)**, and **Claude Opus 5.5 (thinking)** are available on Google AI Pro for **paid (non-trial) subscriptions only**. If you would like to switch from a trial or promotional plan to a paid Google AI Pro subscription immediately, you can [submit an upgrade request](https://support.google.com/googleone/contact/googleone_ai_pro_signup_issues).
- **2. Retirement of Gemini 3.1 Pro:**  **Gemini 3.1 Pro** was retired from individual plans as part of our model lineup update, with **Gemini 3.8 Flash** (`Low`, `Medium`, and `High` thinking) serving as the primary Gemini model across all plans and **Gemini 4 Argon** available on paid (non-trial) Google AI Pro, Ultra, and Enterprise plans ([Choose a model](https://antigravity.google/docs/models/#reasoning-model)).
- **3. If You Are Already on a Directly Paid (Non-Trial) Google AI Pro Plan:** Please update the Antigravity App to the latest release (`v2.24.0`, listed in the [Changelog](https://antigravity.google/docs/changelog/)), sign out of your account completely, and sign back in so your subscription entitlement refreshes.

If you are on a directly paid (non-trial) Google AI Pro subscription and still see `Unavailable` after signing out and back in on `v2.24.0`, please let us know.
