This module integrates Google's Gemini AI models into Drupal for image generation. It allows users to create images from text prompts or transform existing ones, with options for aspect ratio control, high-resolution output, and multi-image composition.
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
