Google Gemini Imagen & Nano Banana API Capabilities
Imagen and Nano Banana are both Google AI image tools, but Imagen 4 is primarily for creating new, realistic images from scratch, while Nano Banana (based on Gemini 2.5 Flash Image) excels at quickly editing existing photos, brainstorming, and creating multi-step image transformations, including the popular 3D figurine trend. While Imagen 4 is known for high photorealism, especially with human subjects, Nano Banana offers greater speed and consistency for iterative workflows, though it still faces common AI image generation challenges like artifacts and potential quality loss in complex edits.
Advanced Image Generation Features
🔄 Multiple Image Generation
- • Generate 1-10 images per request
- • Parallel processing for faster generation
- • Batch processing with progress tracking
- • Configurable generation count
- • Memory-efficient handling of multiple outputs
📐 Aspect Ratio Control
- • Square (1:1) - Perfect for social media
- • Landscape (16:9) - Ideal for banners and headers
- • Portrait (9:16) - Great for mobile content
- • Custom ratios (e.g., 4:3, 3:2, 21:9)
- • Dynamic aspect ratio selection
