What is Qwen 2.1 Text to Image?

Qwen 2.1 Text to Image is Alibaba's image generation model, tuned for photorealism, clean typography, and prompt comprehension across many aspect ratios.

What resolutions and aspect ratios are supported?

1K and 2K resolution tiers, with 9 aspect ratios from 1:1 and 16:9/9:16 to ultra-wide 21:9/9:21.

Can I generate transparent-background images?

Yes — set `background` to `transparent` and use `png` or `webp` as the output format (not supported with `jpeg`).

What does `enhance_prompt` do?

When enabled (the default), the model rewrites your prompt into a fuller scene description before generating, which noticeably improves output quality. Pass `false` to disable it and use your prompt verbatim.

Can I reproduce the same image again?

Yes — pass the `seed` value returned with a previous result together with the same prompt and parameters to reproduce that image.

About Qwen 2.1

Qwen 2.1 Text to Image is Alibaba's text-to-image model for photorealistic scenes, editorial photography, and legible on-image typography from natural-language prompts. It supports opaque and transparent backgrounds, nine aspect ratios, and 1K/2K output resolution, with built-in prompt rewriting that expands short prompts into fuller scene descriptions for sharper, more detailed results. For image editing and recombination instead of pure generation, see [Qwen 2.1 Image to Image](/playground/qwen2-1-image-to-image); for Alibaba's newer generation, see [Qwen 3.0 Text to Image](/playground/qwen3-text-to-image).
