Overview

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.

She wears a simple black backless dress with thin spaghetti straps, showcasing her back, and cradles a large, lush bouquet of orange, apricot, pink, and pale peach roses in her arms, creating a sharp contrast against her dress. The top-left of the frame is covered with dark green vines and small orange flowers draping naturally, partially obscuring a matte dark blue signboard with the white Gothic text \"Il Messaggero\". Below the sign is a blurred glass newsstand window with black metal frames showing hints of newspapers and magazines. The right background features strong golden hour backlighting streaming down a warm-toned, sun-drenched city street, with buildings blurred into soft beige-gray shapes, creating a beautiful bokeh effect and a blurry red traffic sign in the far distance. The entire image has a cinematic, romantic, and bright urban stroll atmosphere, characterized by soft contrast, fine film grain, a shallow depth of field, and stunning backlit highlights."
