Gemini models are missing on Antigravity

From today i can’t able to use the gemini models,only the claude models are only showing

Hi @MEENAKSHI_B,

To help us check why the Gemini models aren’t showing up in your dropdown, could you share a few quick details?

  • Which plan are you using (e.g., Free, Google AI Pro/Plus, Google AI Ultra, or a Google Workspace/Enterprise account), and what does it show under Settings > Models & Usage?

  • What version number is listed under Help > About, and which operating system are you on?

In the meantime, please also check that your Antigravity IDE is updated to the latest version and try pressing Ctrl+Shift+P (Cmd+Shift+P on macOS) β†’ Antigravity: Reset Onboarding to force a fresh sync of your available models.

For me the Gemini 3.1 Pro-Model is missing on Antigravity CLI v1.3.4 (Ubuntu 24.04 LTS).

My plan is Google AI Ultra.

⚠ Warning
⎿  "Gemini 3.1 Pro (High)" is no longer available. Using "Gemini 3.8 Flash (High)".

Hi @Ambati_Rajendra

I’m using Google AI Pro plan currently

And the version number I’m using is Antigravity IDE Version 2.1.1

And I can’t able to update antigravity because of company laptop and others in my office can use the models

Hi @Wolfram_Klatt

But for me only the claude models are shown not even a single gemini model

Very strange. Especially yet it seems to be working for your co-workers at the office.

I tried it on three different servers and all down.

Hi @MEENAKSHI_B,

Could you please share a screenshot of the model selector you are seeing?

Hi @Wolfram_Klatt,

Gemini 3.1 Pro has been retired and is no longer available in Gemini Enterprise.

We recommend switching to Gemini 3.8 Flash. To help you get the same depth and performance you are used to, try these adjustments:

  • Increase reasoning capacity: Use the highest available thinking setting for complex, multi-step, or analytical tasks.
  • Tweak your prompts and Gems: Newer generations interpret instructions differently. Adding explicit structural constraints, requesting step-by-step logic, or supplying few-shot examples will yield significantly better output.

We recognize that Flash behaves differently from 3.1 Pro across certain tasks, and your feedback is essential as we continue tuning performance.

Hi @Ambati_Rajendra ,

thanks for your answer.

Ok, I’ll test Flash 3.8 and let’s see what happens.

Hi @Ambati_Rajendra

Hii please give a solution

Hi @MEENAKSHI_B,

Could you please upgrade to Antigravity v2.5.5? Since you confirmed that currently you are using version 2.1.1, please let me know if the update resolves the issue or if it still persists.

Hello Ambati,

I did what you said, but right now only the Claude models and Gemini 3.8 Flash are showing up. Where are the other models? Also, when will they be available again?

Note: I am a Google AI Pro member.

Best regards,
Arda

Hello @Ambati_Rajendra,

I recently switched from Antigravity version 2.1.1 to version 2.5.5. One noticeable change is that with all three models now include the Gemini 3.8 Flash model too.

However, the Reset Onboarding option no longer seems to work for fixing the model-related issues that I encountered in the previous version (2.1.1).

My main concern is: Where are the other models available under the Google AI Pro plan?

Guys, This same issue i am facing, i think its in India specific only, i am also not able to switch my models.

I won’t able to use the gemini model in antigravity from today what is the issue

I have the exact same problem. The other Gemini models aren’t appearing, only Gemini 3.8 Flash.

I’m having the same problem.
I updated the IDE and only these options showed up. I’m from Brazil

Hi, I’m using Antigravity IDE Version: 2.0.1 in Pakistan as on Pro Plan, every model of Gemini vanished suddenly, it was working earlier today. now I can only see the Claude models and the GPT.

It seems a temporary glitch/bug. I hope this will be fixed shortly.

I’m in the UK and I have the same problem so it’s not specific to India. I am using an old version 2.1.4 - that is a deliberate decision because the UI of the latest version is so different that I haven’t had chance to get my head around it yet. Tempted to upgrade to see if it resolves the issue, but from what I am reading here, that doesn’t seem to be the source of the problem.
