Add Nano banana pro

[XIVIX134]

Hi @Mirrowel ,

Google recently released Nano Banana pro, and it is now officially available on the Antigravity provider.

Could you please add it to the Antigravity model list? it should be listed as gemini-3-pro-image-preview

Reference: https://antigravity.google/blog/nano-banana-pro-in-google-antigravity

Thank you for the update!

@XIVIX134 Thank you for submitting this issue. I am now beginning my analysis and will report back shortly.

Initial Analysis Report

Summary: The gemini-3-pro-image-preview model is already partially integrated in the codebase (alias mapping exists) but is commented out in the AVAILABLE_MODELS list. This is a valid feature request to enable an existing model.

Issue Validation: Confirmed - The request is valid and aligns with the existing code pattern for Antigravity models.

Reproducibility Assessment: Not Applicable - This is a feature request, not a bug.

Root Cause Analysis:

The codebase already has infrastructure for gemini-3-pro-image-preview:

1. Alias mapping exists in src/rotator_library/providers/antigravity_provider.py:95:

   MODEL_ALIAS_MAP = {
       ...
       "gemini-3-pro-image": "gemini-3-pro-image-preview",
       ...
   }

2. Model is commented out in AVAILABLE_MODELS at line 77:

   AVAILABLE_MODELS = [
       ...
       # "gemini-3-pro-image-preview",
       ...
   ]

3. Dev branch shows partial activation - The dev branch has enabled several models (like gemini-3-flash, gemini-2.5-flash) but gemini-3-pro-image remains commented out there as well.

To enable this model, the maintainer would need to uncomment "gemini-3-pro-image-preview" from the AVAILABLE_MODELS list.

Note on Issue Details: The issue mentions "Nano Banana pro" and references an antigravity.google/blog URL. This appears to be a test or placeholder issue, as there is no Google model called "Nano Banana pro" - the actual model name in the codebase is gemini-3-pro-image-preview. If this is a genuine feature request for the Gemini 3 Pro Image model, the implementation path is clear.

Suggested Labels:

• enhancement - Feature request to enable an existing model
• good first issue - Simple one-line change to uncomment the model

Proposed Next Steps:

1. Confirm with user if this is about enabling gemini-3-pro-image-preview
2. If confirmed, uncomment the model from AVAILABLE_MODELS in antigravity_provider.py
3. Test the model with the Antigravity API to ensure proper functionality

Missing Information:

• Clarification on the actual model name (the "Nano banana pro" naming doesn't match any known Google model)
• Whether this model has been tested with the current Antigravity API endpoints

Yes i want gemini 3 pro image preview

[Mirrowel]

It is on the list to do. Problem is it outputs images - it is not a standard model. Needs some.. work for that.
Same goes for audio models and outputs too.

so it won't get enabled??
I saw it in the providers file and i wanted to use it for a project but it wasn't showing up in available models

I don't think it will work at all if you just enable it. I was focused on text-out models first.
You can try by uncommenting of course.

I need to do research first on how this would even work, then implement and test.

@Mirrowel I wanted to thank you for your work. It's so so so useful and I know managing this open source project is probably often times a thankless job. How can I buy you a coffee or something?

Done! Thanks again. Looking forward to the next update with Gemini 3 Flash 👍

Thanks!
It's already live on the dev branch, and been such since flash came out. i didn't have time to finish the changes before holidays, so it's only there for now. It is problem-free to use for now, as most people i "converse" with use it.

Ok Cool. I'll have a look and give it a bash. Thanks again for such a dope tool my man
