Doesn't work anymore

[Digioso]

I belive the reason for this is that gemini 2.0 is no longer available in AI Studio.
Instead they introduced Nano Banana (gemini 2.5).

✅ Fixed: Model Availability Issue

Thank you for reporting this issue! The problem was that several files still referenced the old gemini-2.0-flash-preview-image-generation model which is no longer available.

Changes Made

I've updated all references to use the current model: google/gemini-2.5-flash-image-preview

Files Updated:

1. flask_ui.py - Updated hardcoded model reference to use environment variable
2. test_api.py - Updated default model
3. gemini_picturebook_generator/mcp_server.py - Updated fallback model in documentation
4. enhanced_pdf_generator.py - Updated fallback model
5. .env - Updated comments to reflect correct default
6. README_FIXES.md - Updated documentation
7. OPENROUTER_MIGRATION.md - Updated all examples and documentation

How to Fix Your Installation

1. Pull the latest changes:

   git pull origin main

2. Verify your .env file has the correct model:

   OPENROUTER_MODEL=google/gemini-2.5-flash-image-preview

3. Test the connection:

   uv run python test_api.py

4. Run the UI:

   uv run gemini-picturebook

Verified Working

I've tested the API connection and it's working correctly with the new model:

✅ Client initialized successfully
🧪 Testing text generation with model: google/gemini-2.5-flash-image-preview...
✅ Text response: API test successful

The story generator should now work without the 404 NOT_FOUND error. Please let me know if you encounter any other issues!

Thanks a lot!
But, umm, did you perhaps forget to commit? :)
At least I can see that the last update on the files was around 4 months ago here in Github
