ai_provider_nanobanana

Overview

NanoBanana is an AI provider plugin for the Drupal AI module that integrates Google's Gemini image generation models. It supports both text-to-image and image-to-image generation with advanced features like multi-image composition, aspect ratio control, and high-resolution output.

With the Nano Banana Editor Module we have also a POC for a nicer editor experience
