Qwen Image 3.0 vs Seedream 5.0 Pro: limits and notes

Qwen Image 3.0

Qwen Image 3.0 combines Base and Pro image generation and editing in one model. Pro is selected by default, output starts at 2K, and aspect ratio starts in Auto. Base provides a lower-cost option for fast iteration.

Variants

• Choose qwen-image-3.0-pro for photorealism, dense layouts, fine multilingual typography, and complex multi-image edits.
• Choose qwen-image-3.0 for lower-cost generation and routine edits.
• Choose with model_variant. Without it, the model ids qwen-image-3.0, alibaba/qwen-image-3.0 and alibaba/qwen-image-3-0 run Base and every other id of this model runs Pro.

Modes

• Text to image from a prompt.
• Image editing and reference-guided generation from one to three images.
• Direct prompt extension works for generation and editing. Agent prompt extension provides deeper refinement for text-to-image requests only.

Output and input limits

• One to six output images per request.
• 1K, 2K, automatic, aspect-ratio presets, or an exact custom size.
• Preset and custom sizes stay between 512x512 and 2048x2048 pixels, with each selected side up to 2048 pixels and aspect ratio from 1:8 to 8:1. Automatic sizing can choose its own dimensions within the 1K or 2K output tiers.
• Input images can be JPG, JPEG, PNG, BMP, TIFF, WEBP, or GIF, up to 10 MB each.
• Prompts support up to 4,500 tokens.

Billing

• Base uses one output rate across 1K and 2K.
• Pro outputs up to 2.25 megapixels use the 1K rate. Larger Pro outputs use the 2K rate.
• Every reference image adds the input-image rate shown above.

Performance

• 1K generations are optimized for interactive iteration. Complex 2K edits can take several minutes.

Content safety

Generated images pass an automated content-safety check. An image flagged as explicit is not returned. Because the image is generated before the check runs, a flagged generation is still billed.

Seedream 5.0 Pro

Modes

• Text to image
• Single or multi-image to image
• Interactive editing with coordinate or sketch markers
• Layer decomposition into a base image plus up to 16 layers

Interactive editing

Mark the region to change directly on the input image with a sketch, circle, or arrow, then describe it in the prompt. For exact placement, use coordinate tags on a 0 to 1000 normalized grid:

Place the subject from image 1 <bbox>179 283 796 986</bbox> at the position in image 2 <bbox>118 331 933 871</bbox>.

Layer decomposition

Set layer_decomposition to true with exactly one input image to split it into a base image plus up to 16 transparent PNG layers. Every returned image carries its stacking order as z_index, and each layer also carries its position in the base image as bounding_box.absolute and bounding_box.normalized, plus a name and a description. Leave the prompt empty to let the model choose the elements, or name the elements or coordinate regions to separate. Resolution accepts 1K, 1.5K, or 2K, and matches the input image when unset.

Prompt optimization

• Standard (default): prioritizes prompt adherence and image quality
• Fast: reduces generation latency with slightly lower image quality

Limits

• One output image per request, except layer decomposition, which returns the base image plus its layers
• Up to 10 reference images, and exactly one for layer decomposition or a transparent background
• 1K, 1.5K, and 2K resolution tiers
• PNG or JPEG output, and layers are always PNG
• A transparent background needs one input image that already has an alpha channel, and PNG output
• No grouped output, streaming, or web search

Billing

Layer decomposition bills every returned image, the base image and each layer, at half the standard per-image rate, tiered on the pixel count of that image.

Content safety

Generated images pass an automated content-safety check. An image flagged as explicit is not returned. Because the image is generated before the check runs, a flagged generation is still billed.

How to call Qwen Image 3.0 and Seedream 5.0 Pro

Qwen Image 3.0 runs through POST /v1/images/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Or add "sync": true to skip polling: the request stays open and returns the finished OpenAI-style image response directly, so OpenAI SDKs work as-is. Both models are called through the same endpoint. Set model to qwen-image-3-0 or seedream-5-0-pro. Get an API key from the EmpirioLabs dashboard.

curl https://api.empiriolabs.ai/v1/images/generations \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen-image-3-0",
    "prompt": "Describe what you want Qwen Image 3.0 to generate."
  }'
