## Summary

Alibaba’s Qwen team launched **Qwen-Image-2.1**, an open-source AI model that merges text-to-image creation and image editing into one system. A standout feature is **native transparency support**, allowing users to generate or edit RGBA images with transparent backgrounds directly from text prompts. It also enables multi-image editing with up to **10 reference images** for composition tasks, preserving details like lighting and textures.

Optimizations like **mixed-granularity attention** and **prefix KV-cache reuse** reduce computational redundancy for tasks involving multiple edits. The model is available on **Hugging Face and ModelScope**, with **Day-0 support** for tools like **Diffusers, ComfyUI, vLLM-Omni, and SGLang**.

## Key points

- Supports **native transparency** (RGBA images) and multi-image editing with up to 10 reference images
- Optimized for efficiency via mixed-granularity attention and KV-cache reuse, available on Hugging Face and ModelScope

## Why it matters

This model expands open-source image tools with transparency and multi-reference editing, lowering barriers for creators who need precise control over visuals without proprietary costs.
