# qwen-image-2.1-pro

> Qwen-Image-2.1-Pro is an image model in the Qwen family that balances generation quality, inference efficiency, and cost. Qwen-Image-2.1 unifies text-to-image generation and image editing in a single model, with just 7B parameters in its visual generation component and native support for generating and editing transparent images. This update introduces four key improvements: Compact and efficient: A lightweight architecture and inference optimizations balance image quality and computational cost. Native transparency, unified creation and editing: Generate regular or transparent images from prompts, edit transparent layers, and extract subjects from photos. Versatile editing: Use up to 10 reference images, specify local edits, preserve people and products, and handle a wide range of tasks. Realistic textures and refined aesthetics: Improved typography, portrait lighting, and fine details make generated images more visually compelling.
