MFLUX v.0.8.0 Release Notes

Experimental AI Features

👗 CatVTON (Virtual Try-On)

• [EXPERIMENTAL] Added virtual try-on capabilities using in-context learning via mflux-generate-in-context-catvton
• Support for person image, person mask, and garment image inputs for comprehensive virtual clothing try-on
• Automatic prompting for virtual try-on scenarios with optimized default prompts
• Side-by-side generation showing garment product shot alongside styled result
• AI-powered virtual clothing fitting with realistic lighting and fabric properties

✏️ IC-Edit (In-Context Editing)

• [EXPERIMENTAL] Added natural language image editing capabilities via mflux-generate-in-context-edit
• Natural language image editing using simple text instructions like "make the hair black" or "add sunglasses"
• Automatic diptych template formatting for optimal editing results
• Optimal resolution auto-sizing for 512px width (the resolution IC-Edit was trained on)
• Specialized LoRA automatically downloaded and applied for enhanced editing capabilities

Enhanced Generation Control

Architecture Improvements

📚 Documentation Structure

• Refactored "In-Context LoRA" section to "In-Context Generation" with clear subcategories
• Enhanced documentation structure for better organization and user navigation
• Improved categorization of experimental vs stable features

🔄 Code Architecture Changes

• Class rename: Flux1InContextLora is now Flux1InContextDev to better reflect the dev model variant
• Module reorganization: Moved from mflux.community.in_context_lora.flux_in_context_lora to mflux.community.in_context.flux_in_context_dev
• Breaking change for library users: If you import the class directly, update your imports accordingly

⚡ Performance Optimizations

• Updated MLX dependency to latest version for improved performance and stability
• Removed PyTorch dependency for DepthPro model, significantly reducing installation requirements
• Streamlined dependencies for faster installation and reduced disk usage

Experimental Notice

⚠️ Important: CatVTON and IC-Edit features are experimental and may be removed or significantly changed in future updates. These features represent cutting-edge AI capabilities that are still under active development.
