Qwen Image 3 Edit API Pricing: $0.048/image · Image Editing

What is Qwen Image 3 Edit?

Qwen Image 3 Edit is the editing half of Alibaba's Qwen Image 3. Give it one to three reference images and a plain-language instruction, and it applies the change while preserving key details such as facial features and identity. When you pass more than one image, refer to them in the prompt as image 1, image 2 and image 3. With no aspect ratio set, the edit renders at the standard 1K framing closest to your first input image — square, 4:3 or 16:9, in the same orientation. Choosing an aspect ratio renders the edit at that framing instead. Prompts can be written in English or Chinese, and a negative prompt names what to keep out. Billing is per edited image, at the model's cost plus a flat 20% platform fee, shown before you spend.
