Qwen released Qwen-Image-2.1, a 7B single-stream-DiT model for unified text-to-image generation and editing with mixed-granularity attention, prefix KV cache reuse, native RGBA/transparency support, and editing driven by up to 10 reference images or mask/annotation input. Two companion models built on Qwen3.5-VL-9B — PE-T2I (rewrites any-language prompts into detailed English prompts plus an aspect ratio) and PE-I2I — were published alongside it on Sept 20.

Why it matters

Native transparency plus a dedicated prompt-enhancer stack makes this the first major open-weights image release to ship generation, layer editing, and prompt engineering as one pipeline.
