-# FLUX.1-dev-Picasso
+# FLUX.1-dev Picasso Edition
 
 Generate high-quality images in Pablo Picasso's distinctive cubist style using the FLUX.1-dev model from Black Forest Labs.
 
-This is a demo application that integrates with external APIs to provide Picasso-style image generation capabilities.
+This is a specialized version of the original [FLUX.1-dev Space](https://huggingface.co/spaces/black-forest-labs/FLUX.1-dev) customized for Picasso-style art generation.
+
+## Features
+
+- **Automatic Picasso-style prompt enhancement** - adds cubist, geometric, and bold color descriptors
+- **Optimized UI layout** - improved slider positioning and descriptions
+- **User-friendly error messages** - helpful feedback instead of technical errors
+- **PNG download format** - better compatibility than WebP
+- **Example prompts** - one-click access to curated Picasso-style examples
+
+## Changes from Original FLUX.1-dev
+
+### Core Functionality
+- **Prompt Enhancement**: All prompts automatically enhanced with Picasso-style descriptors:
+  - "in the style of Pablo Picasso, cubist painting, abstract art, geometric shapes, fragmented forms, bold colors"
+- **Title**: Changed from "FLUX.1-dev" to "FLUX.1-dev Picasso Edition"
+
+### UI/UX Improvements
+- **Layout Optimization**:
+  - Model attribution moved below subtitle without "Model Attribution:" label
+  - Guidance Scale and Inference Steps slider positions swapped
+  - Status box height reduced from 6 to 3 lines
+
+- **Slider Descriptions**: Enhanced two-line descriptions explaining higher/lower values:
+  - Guidance Scale: "Higher values = more faithful to prompt / Lower values = more creative interpretation"
+  - Inference Steps: "Higher values = better quality but slower / Lower values = faster but less refined"
+
+- **Example Buttons**: 
+  - Show full enhanced prompts in text field (not just simple prompts)
+  - No auto-generation - users review prompt before generating
+  - 5 curated example prompts for common Picasso subjects
+
+### Technical Improvements
+- **GPU Stability**: Increased duration from default to 100 seconds
+- **Memory Management**: Added `torch.cuda.empty_cache()` after generation
+- **Device Handling**: Proper device variable usage with CUDA availability checks
+- **Error Handling**: User-friendly messages with emojis and actionable guidance:
+  - GPU issues: "🔄 GPU temporarily unavailable. Please try again in a moment!"
+  - Timeouts: "⏱️ Generation timed out. Please try again with fewer inference steps or try again later!"
+  - Model loading: "🚀 Loading AI model... Please wait a moment and try again!"
+
+### Format Changes
+- **Image Downloads**: Set to PNG format instead of WebP for better compatibility
+
+## Usage
+
+1. Enter a prompt describing what you want to see
+2. Adjust Guidance Scale (prompt adherence) and Inference Steps (quality vs speed)
+3. Click "Generate Picasso-Style Image" or use example prompts
+4. Download results in PNG format
