Jio Google AI Pro Subscribers – Third-Party Model Access Restriction

Google Antigravity

1

Hello, I have an active 18-month Google AI Pro subscription through Google’s official Jio partnership offer.

I am using Google Antigravity, but it says that third-party model access, including Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS 120B, will no longer be available after November 18.

I want to understand why my Google AI Pro membership does not qualify for these models.

Could you please transfer my request to the Google AI Pro / Antigravity specialist team and clarify whether there is any way to obtain this access under my existing subscription?

Hi @scotchszn-bhavesh,

Welcome to the Forum, and thank you for reaching out.

Here is how model eligibility works for your Jio-bundled Google AI Pro plan:

  • November 18 Model Retirements & Third-Party Access: Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120b are being retired across all plans on November 18, 2026 (Choose a model). Replacement third-party models (Claude Sonnet 5.5 and Claude Opus 5.5) are available on Google AI Pro for non-trial (paid) subscriptions only, and Gemini 4 Argon requires a paid Google AI Pro plan or an eligible premium device trial (Choose a model). Because the 18-month Jio offer is provisioned as a partner promotional trial, it does not include these models, though your account keeps the Google AI Pro 5-hour quota refresh and higher weekly rate limits on Gemini 3.8 Flash (Plans).
  • How to Access These Models: Partner-billed promotional plans cannot be converted in place while retaining promotional months (Manage third-party subscriptions). To access Claude 5.5 and Gemini 4 Argon, you can submit a request to cancel the trial and switch to a paid plan (Upgrade FAQ), or subscribe to a paid Google AI Pro or Google AI Ultra plan on Google One using a separate Google Account so you retain your 18-month Jio benefits on your primary account.

Please let us know if you need any further information.
