Concerns regarding model access restrictions for Promotional/Student Google AI Pro subscribers ahead of the Nov 2 removals

Google Antigravity users on promotional, partner-bundled, and discounted subscriptions deserve clarity about model availability and upcoming model removals.

Many of us chose Google AI Pro because of the overall value of the subscription, including access to powerful AI models for serious software development. Some users subscribed through carrier partnerships, while others rely on student discounts or introductory promotions.

However, Google’s current model eligibility rules exclude certain promotional subscribers from Claude Sonnet 5.5 and Claude Opus 5.5, while older third-party models are scheduled for removal on November 2, 2026. Meanwhile, Gemini 4 Argon is currently restricted to Ultra subscribers in Antigravity.

This raises legitimate questions about transparency, fairness, and the expectations created by the Google AI Pro name when model access differs depending on how a subscription was obtained.

We are asking Google to:

  • Clearly disclose model-access restrictions for every promotional, student, discounted, and partner-bundled subscription.
  • Explain why subscribers paying for, or receiving, the same named plan may have significantly different model access.
  • Provide a reasonable alternative when existing models are retired.
  • Consider extending access to newer models or offering an equivalent benefit to affected subscribers.
  • Clarify what options are available to users who subscribed based on the advertised benefits.

If you’re affected, share your experience, screenshots of the advertised offer and its terms, and any official responses you’ve received.

If the terms advertised to consumers materially differ from what they receive, affected users should consider contacting the relevant consumer-protection authorities in their jurisdiction to understand their rights.

This is a call for transparency and fair treatment across all promotional and discounted subscription programs, not just one carrier or country.

Let’s keep the discussion factual, document the differences, and ask Google for a clear and consistent policy.

All Gemini models missing in Antigravity IDE

I’m using Antigravity IDE on Windows 64-bit with Google AI Pro. Claude and GPT models appear in the model selector, but all Gemini models are missing.

I’ve downloaded the Windows 64-bit IDE, restarted the application, and tried resetting onboarding and signing in again. The issue persists.

My Gemini quota was previously showing 100% remaining. Please investigate whether this is an account entitlement, model-catalog synchronization, or server-side issue.

Hi @AbuMaher,

Thank you for raising this and sharing your feedback ahead of the November 2, 2026 model transition. Here is an update on how model access works across Google AI Pro, promotional/partner plans, and Google Workspace accounts:

Gemini 4 Argon & Claude 5.5 on Paid Google AI Pro Plans: Gemini 4 Argon (High, Medium, and Low), along with Claude Sonnet 5.5 and Claude Opus 5.5, is now available to paid Google One AI Pro and Google One AI Ultra subscribers in Antigravity, with a dedicated weekly Gemini 4 Argon quota on top of your existing Gemini 3.8 Flash quota.

Promotional, Partner-Bundled, and Student Trial Plans: While the Gemini web app includes frontier models during promotional offers, Frontier Model access in Antigravity (Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5) requires an active, directly billed paid Google One AI Pro or AI Ultra subscription.

After November 2, 2026: When Claude 4.6 and GPT-OSS are retired on November 2, accounts on student promotional trials or third-party carrier/partner bundles will continue to have full access to Gemini 3.8 Flash (High, Medium, and Low) in Antigravity.

How to unlock frontier models: Access to Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5 unlocks automatically once a trial converts to a paid billing cycle or if you switch to a direct paid Google One AI Pro or Google One AI Ultra plan at one.google.com/plans (or set up pay-as-you-go billing via Google Cloud / Vertex AI).

Google Workspace & Business Accounts: Consumer Google One plan benefits apply only to personal Google accounts (@gmail.com). For Google Workspace and business accounts, Gemini 4 Argon and Claude 5.5 are available through Gemini Enterprise and Antigravity Business (Vertex AI pay-as-you-go) under your organization’s Google Cloud project. You can set this up anytime by following the Antigravity Enterprise Setup Guide.

@Chandana_S, regarding all Gemini models missing in the Antigravity IDE: older IDE builds don’t show the current Gemini models. Please update the Antigravity IDE to the latest version (Help → Check for Updates, or re-download from Google Antigravity - Download) and restart it. If Gemini models are still missing after updating, please open a separate topic with your IDE version (Help → About) and a screenshot of the model selector, so we can look into it.

We appreciate your feedback on making plan and trial eligibility requirements clearer across our sign-up and in-product notices, and we have shared this directly with the product team.

We can’t even cancel our student trial to actually pay for it though. I’d cancel the year long trial to the $20/mo pro plan and resubscribe actually paying for it, but that’s not even possible.

Have you tried to reach out to the support team aside from this forum. My sister had a similar issue and it was handled, but I believe it’s case-by-case.

I’ll give that a shot, thanks for telling
