This post details new Firebase AI Logic capabilities for image generation, specifically Imagen editing and Gemini 2.5 Flash Image. Imagen offers inpainting and outpainting, allowing targeted image modifications using masks with greater control over artistic detail. Gemini 2.5 Flash Image ("Nano Banana") excels at conversational image editing, employing world knowledge for contextually relevant visuals. Imagen focuses on photorealistic outputs and specific styles, while Gemini 2.5 Flash Image is ideal for dynamic illustrations. Implementing Imagen involves defining inpainting functions with source images, masks, and prompts. Gemini 2.5 Flash Image uses multi-turn chat to iteratively edit images. The post provides code snippets for both Imagen and Gemini 2.5 Flash Image, demonstrating their implementation. It emphasizes the importance of AI safety when integrating these models. Both tools offer ways to customize apps and improve user engagement via image generation. The choice between models depends on the specific needs of your application.
