+Nano Banana PRO
+AI-Powered Image Style Transfer with Outpainting & Auto-Upscaling (4x)Overview
+Nano Banana PRO is a Gradio-based web application that leverages the google/nano-banana model from Replicate API for image style transfer. Users can apply desired styles to uploaded images, optionally expand image boundaries (outpainting), and automatically perform 4x upscaling.Key Features
+1. Style Transfer
+
+AI-powered style transfer with 1-2 uploaded images
+Fine-grained style control via text prompts
+Powered by google/nano-banana model
+2. Outpainting (Optional)
+
+Image boundary expansion functionality
+Multiple aspect ratio support (9:16, 16:9, 1:1, custom)
+5 alignment options (center, left, right, top, bottom)
+Adjustable mask overlap ratio (1-50%)
+Image resize options (full, 50%, 33%, 25%, custom)
+3. Auto Upscaling
+
+Automatic Real-ESRGAN 4x upscaling for all generated images
+High-quality image output guaranteed
+4. ZeroGPU Optimization
+
+Optimized for Hugging Face Spaces ZeroGPU environment
+Efficient GPU resource management
+Memory management and timeout prevention logic
+Tech Stack
+Required Libraries
+
+gradio: Web interface
+spaces: Hugging Face Spaces GPU support
+replicate: Replicate API client
+Pillow (PIL): Image processing
+requests: HTTP request handling
+numpy: Numerical operations
+Models Used
+
+Main Model: google/nano-banana (style transfer)
+Upscaling Model: nightmareai/real-esrgan (4x upscaling)
+Usage
+Basic Usage
+
+Enter style description text
+Upload 1-2 images
+Click "Generate Magic with Auto-Upscale" button
+View and download processed image
+Outpainting Usage
+
+Check "Enable Outpainting" checkbox
+Enter outpaint prompt
+Set target aspect ratio and size
+Select alignment option
+Preview with "Preview Outpaint Mask"
+Click generate button
+Limitations
+
+Maximum processing time: 180 seconds (GPU duration)
+Maximum image size: 2048x2048 pixels
+Replicate API token required
+Internet connection required (external API calls)
+Error Handling
+Main Error Responses
+
+Timeout: Automatically returns original image
+API Error: Retry logic applied
+Memory Shortage: Automatic garbage collection
+Upscaling Failure: Returns original generated image
+Performance Optimization
+
+Reduced processing time with automatic image resizing
+Improved memory efficiency with timely intermediate variable deletion
+Network stability through retry logic
+Duration settings optimized for ZeroGPU environment
