Qwen Image Text To Image LoRA

Playground

Qwen-Image LoRa — a 20B MMDiT model for next-gen text-to-image generation with LoRA.

Features

Qwen-Image — a 20B MMDiT model for next-gen text-to-image generation. Especially strong at creating stunning graphic posters with native text. Now open-source.

Key Highlights:

SOTA text rendering — rivals GPT-4o in English, best-in-class for Chinese
In-pixel text generation — no overlays, fully integrated
Bilingual support, diverse fonts, complex layouts

Also excels at general image generation — from photorealistic to anime, impressionist to minimalist. A true creative powerhouse.

Parameters

Task Submission Parameters

Request Parameters

Parameter	Type	Required	Default	Range	Description
prompt	string	Yes		-	Text prompt for image generation.
size	string	No	1024*1024	256 ~ 1536 per dimension	The size of the generated media in pixels (width*height).
loras	array	No		max 3 items	List of LoRAs to apply (maximum 3).
loras[].path	string	Yes	-		Path to the LoRA model
loras[].scale	float	Yes	-	0.0 ~ 4.0	Scale of the LoRA model
seed	integer	No	-1	-1 ~ 2147483647	The random seed to use for the generation. -1 means a random seed will be used.
output_format	string	No	jpeg	jpeg, png, webp	The format of the output image.
enable_sync_mode	boolean	No	false	-	If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API.
enable_base64_output	boolean	No	false	-	If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.

Response Parameters

Parameter	Type	Description
code	integer	HTTP status code (e.g., 200 for success)
message	string	Status message (e.g., “success”)
data.id	string	Unique identifier for the prediction, Task Id
data.model	string	Model ID used for the prediction
data.outputs	array	Array of URLs to the generated content (empty when status is not `completed`)
data.urls	object	Object containing related API endpoints
data.urls.get	string	URL to retrieve the prediction result
data.has_nsfw_contents	array	Array of boolean values indicating NSFW detection for each output
data.status	string	Status of the task: `created`, `processing`, `completed`, or `failed`
data.created_at	string	ISO timestamp of when the request was created (e.g., “2023-04-01T12:34:56.789Z”)
data.error	string	Error message (empty if no error occurred)
data.timings	object	Object containing timing details
data.timings.inference	integer	Inference time in milliseconds
