Qwen Image 2.1 Text to Image

Size

Qwen Image 2.1 has native 2K (2048*2048) support for direct output.

Output size comes from ResolutionSelector (width/height). Default is 1 megapixel (10241024). For native 2K, set 1:1 and 4 megapixels (20482048). Prefer multiples of 32.

Transparent Image

To generate a transparent image, wrap the prompt like this and replace the middle with the subject:

---

This is an RGBA format image with transparency. [your description]. The image has an alpha channel and a transparent background.

---

Save as PNG to keep the alpha channel.

Parameters

• prompt: what to generate. For RGBA, see Note: transparent.
• negative_prompt: unused while cfg is 1.
• cfg: keep 1 for the Qwen Image 2.1 official path. Raise it only if you use a negative prompt.
• steps: Qwen Image 2.1 official pipeline uses about 40-50 with euler. This template starts at 25. More advanced samplers need fewer steps.
