Hi @Indrajit_Sharma,

Thanks for reaching out. Gemini 4 Argon briefly appeared around October 14 while model access was being updated, but it was removed because it is only available on non-trial, directly paid Google AI Pro subscriptions.

  • Why Argon Is Not Included on Jio Plans: Google AI Pro plans bundled through Jio are provisioned as promotional partner memberships. Promotional and trial plans do not include Gemini 4 Argon or Claude 5.5 (Models documentation).
  • What Your Jio Plan Includes: You still have full access to Gemini 3.8 Flash (Low, Medium, and High thinking) with the 5-hour refreshing Google AI Pro baseline quota, plus Claude 4.6 and GPT-OSS 120B until they retire on November 2, 2026.
  • How to Unlock Gemini 4 Argon: If you want to switch from your promotional plan to a paid Google AI Pro subscription to unlock Gemini 4 Argon and Claude 5.5, you can submit an upgrade request.

Let us know if you have any other questions!
