Hi Support Team,

I am currently using Antigravity with an active Google AI Pro plan activated via the Jio 18-month partner promotion.

However, the “Gemini 4 Argon” model is completely missing from my available models dropdown. I have already cleared my local application cache, reset my onboarding state, and re-authenticated my account, but the model still fails to appear.

Could you please check my account entitlements and manually provision/whitelist my account for the Gemini 4 Argon model?

Affected Account Email: s****gmail.com
Platform: Antigravity

I have attached a screenshot confirming my active Google AI Pro subscription tier. Thank you!

Hi @Sanjeev_Kumar1,

Gemini 4 Argon is not available on your account because partner-bundled promotional offers—such as the Jio 18-month Google AI Pro promotion—are provisioned as promotional/trial memberships rather than directly billed subscriptions, and our support team cannot manually whitelist or provision individual accounts for this model. Per the official Models documentation, Gemini 4 Argon on Google AI Pro is available only with paid (non-trial) Google AI Pro plans or on trial with eligible premium devices (as well as on Google AI Ultra and Enterprise plans).

Here is what is included with your current plan and your options if you want access to Gemini 4 Argon:

  1. Your active Jio Google AI Pro plan provides the Google AI Pro baseline quota (a high, generous quota refreshed every five hours until the weekly limit is reached; see Plans) with Gemini 3.8 Flash (Low, Medium, and High thinking levels—we recommend using High for complex coding and architectural tasks). You also have access to Claude Sonnet 4.6 (thinking), Claude Opus 4.6 (thinking), and GPT-OSS-120b (note that these three models are scheduled to be removed on November 2, 2026 per the Models page).
  2. To access Gemini 4 Argon (as well as Claude Sonnet 5.5 (thinking) and Claude Opus 5.5 (thinking)), you can submit a request to Google One Support to cancel your promotional trial and switch to a directly paid Google AI Pro plan, or upgrade directly to a paid Google AI Ultra plan on Google One. For more details on partner-bundled memberships, see our Upgrade FAQ and Google One’s guide on managing third-party subscriptions.
  3. If you are using an older build of the standalone Antigravity IDE (such as v2.5.5), note that Gemini 4 Argon support in the standalone IDE was added in v2.6.0 (and is supported in the Antigravity App v2.28.1 at antigravity.google/releases), though selecting it still requires a directly paid Google AI Pro or Google AI Ultra subscription.

So I paid for google AI pro to not get google AI pro?
This is disappointing, why not just subscribe to Claude with the same price then?
