Hello,

I've encountered an issue with image generation.

When I don't attach a reference image, image generation works correctly with every available model.

However, as soon as I attach a reference image, the selected model is ignored and image generation is automatically handled by Nano Banana instead. This means I can't use other image generation models with an attached reference image.

Expected behavior:

The model I select should remain in use even when a reference image is attached.

Actual behavior:

Attaching a reference image automatically switches image generation to Nano Banana, regardless of which model I selected.

Thank you.
