qwen-image-3.0

Capabilities

• Balanced speed and quality for image generation and editing.
• One to six outputs and up to 3 ordered reference images per request.
• Custom output sizes or auto, reproducible seed input, prompt enhancement and watermark controls.
• Synchronous OpenAI generation/editing and Bailian native request formats.

Limitations

• No masks, streaming or Base64 output; completed images are returned as URLs.
• At most 3 reference images; each reference must be at most 10 MB.
• Image generation is probabilistic; a seed does not guarantee identical results.

Use cases

• Product and advertising visuals.
• Reference-based restyling and image revision.
• Programmatic creative workflows with direct synchronous results.
