Qwen Image 3.0 - Oxen.ai

Try Qwen Image 3.0 in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: qwen-image-3 Qwen Image 3.0 is the standard tier of Alibaba’s Qwen Image 3.0 series, a closed model that handles text-to-image generation and image editing in one endpoint and balances quality against speed and cost. It reads prompts up to 4,500 tokens, renders text in 12 languages, and can reason about the prompt before rendering. It takes up to three input images for edits and composition, outputs any size from 512x512 to 2048x2048 total pixels at one flat price, and picks a resolution from the prompt when none is set. Use the Pro tier when small text or complex layouts need the extra fidelity. Weights are not published.

Metric	Value
Context Length	4,500 tokens
Max Resolution	2048x2048 (2K)
Multilingual	Yes (12 languages)

Request parameters

Required parameters

Field	Type	Default	Description
`prompt`	`string`	—	Text prompt describing the image to generate, or the edit to apply. Up to 4,500 tokens. Use @Image1, @Image2, etc. to reference the input images.

Optional parameters

Field	Type	Default	Description
`input_images`	`array<string>`	—	Optional input images to edit or combine. The output keeps the aspect ratio of the last image unless an aspect ratio is chosen. Reference them in the prompt as @Image1, @Image2, etc. Up to 3 images.
`aspect_ratio`	`string`	`"auto"`	Aspect Ratio One of: auto, 16:9, 9:16, 1:1, 4:3, 3:4.
`resolution`	`string`	`"2K"`	Resolution One of: 1K, 2K.
`num_images`	`integer`	`1`	Number of images to generate, 1 to 6. Only the first is returned; all are billed. Range: 1 – 6.
`enable_prompt_expansion`	`boolean`	`true`	Let the model rewrite the prompt with more detail before rendering. Turn off for tighter control over the wording.
`enable_thinking`	`boolean`	`true`	Reason about the prompt before rendering. Improves quality on complex layouts and long prompts at the cost of generation time. Requires prompt expansion.
`negative_prompt`	`string`	—	What to keep out of the image.
`seed`	`integer`	—	Seed for reproducible generation, 0 to 2147483647.
`watermark`	`boolean`	`false`	Add an AI-generated watermark in the bottom-right corner.
