Argon appeared around 14 October but could not be used, and has since disappeared despite having active Jio Google AI Pro subscription.

Jio is considered as promotional or trial and Hence the same is not made available for jio users.

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](https://antigravity.google/docs/models#reasoning-model)).
- **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](https://antigravity.google/docs/plans#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](https://support.google.com/googleone/contact/googleone_ai_pro_signup_issues).

Let us know if you have any other questions!
