Qwen - Text to Image
High-quality photorealistic image generation powered by Qwen’s advanced AI model
Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:Get Task Details
Learn how to query task status and retrieve generation results
For production use, we recommend using the
callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.Related Resources

type: string
enum:
- qwen/text-to-image
default: qwen/text-to-image
description: |-
The model name to use for generation. Required field.
- Must be `qwen/text-to-image` for this endpoint

callBackUrl:
type: string
format: uri
description: >-
The URL to receive generation task completion updates.
Optional but recommended for production use.
- System will POST task status and results to this URL when
generation completes
- Callback includes generated content URLs and task
information
- Your callback endpoint should accept POST requests with
JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll
task status
