# Qwen-Image-2.1 7B — INT4 (W4A8) ConvRot for ComfyUI

INT4 quantized weights of **Qwen-Image-2.1** for fast, low-VRAM inference in ComfyUI.

This is a modified (quantized) version of the Qwen-Image-2.1 model. It is not an official Qwen release and is not endorsed by the Qwen team.

## About Qwen-Image-2.1

A unified text-to-image generation and image editing model in the Qwen family. With just 7B parameters in its visual generation component (32 Single-Stream DiT layers), Qwen-Image-2.1 balances generation quality, inference efficiency, and versatility.

### Highlights

- **Efficient Image Generation** — combines strong visual performance with fast inference and a compact design, making high-quality image creation accessible across a wide range of creative workflows.
- **Flexible Creative Control** — supports diverse inputs, outputs, and localized edits, giving creators the flexibility to explore ideas and refine details within a unified workflow.

### Key improvements in 2.1

- **Compact and Efficient** — lightweight architecture with mixed-granularity attention and prefix KV cache reuse delivers strong image quality at low computational cost.
- **Native Transparency, Unified Creation and Editing** — generate regular or transparent (RGBA) images from text, edit transparent layers, and extract subjects from photographs — all in one model.
- **Versatile Editing** — support up to 10 reference images, specify local edits via circles, painted annotations, or separate masks, and preserve identity for people and products.
- **Realistic Textures and Refined Aesthetics** — improved typography, portrait lighting, and fine details for more visually compelling results.
