Qwen 开源 Qwen-Image-2.1：7B 统一生成与编辑并原生支持透明图像
Qwen released open-source Qwen-Image-2.1, a unified text-to-image generation and editing model with a compact 7B-parameter visual component (32 Single-Stream DiT layers) that natively generates and edits transparent RGBA images. It supports up to 10 reference images, local editing via circles/scribbles/masks, and subject extraction from photos, using mixed-granularity attention with KV cache reuse for faster inference. The update improves portrait identity and product fidelity, typography, and lighting, targeting design, e-commerce, and visual storytelling workflows.

score 7 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
