Gemini 4 Hydrogen blocked despite active Jio Google AI Pro quota – Antigravity CLI v1.5.9

Hello Google Antigravity Team,

I’m using the official 18-month Jio Google AI Pro subscription in India.

My Antigravity account correctly displays Google AI Pro quota, and Gemini 3.8 Flash works normally.

However, Gemini 4 Hydrogen appears in the model selector but returns:

“Only available for paid Pro and Ultra plan users.”

Gemini 4 Argon also shows the same paid Pro/Ultra restriction.

My environment:

  • Subscription: Google AI Pro (provided by Jio)
  • Country: India
  • CLI version: 1.5.9
  • Gemini 3.8 Flash: Working
  • Gemini 4 Hydrogen: Unavailable
  • Gemini 4 Argon: Unavailable

I understand that Argon may be restricted to directly billed subscriptions. However, your representative confirmed that Gemini 4 Hydrogen should be available across all plans, including Jio promotional subscriptions.

Could you investigate the server-side entitlement mapping for Jio Google AI Pro accounts?

Thank you.
