What is the Qwen 2.1 API?

The Qwen 2.1 API gives applications programmatic access to Alibaba's Qwen 2.1 image model — text-to-image generation with strong prompt comprehension and legible typography, and reference-image editing that can recombine up to 10 images or apply a masked local edit.

Muapi exposes both Qwen 2.1 endpoints through one REST API. Use the Qwen 2.1 playground or the API directly, and compare it against Qwen 3.0 and every other image model in the catalog.

What Qwen 2.1 can do

Photorealistic Generation

Renders realistic scenes, portraits, and product shots with legible on-image typography.

Multi-Image Editing

Combine and edit up to 10 reference images in a single request, in the order the prompt refers to them.

Local Inpainting

Supply a mask to regenerate only the white-marked region of one reference image, leaving the rest untouched.

Transparent Backgrounds

Output a real alpha channel on PNG or WebP for drop-in compositing.

9 Aspect Ratios

From square 1:1 to ultra-wide 21:9/9:21, plus an auto mode that matches the first reference image.

1K / 2K Resolution

Choose the faster 1K tier or 2K for four times the pixels.
