Wan2.7 Image vs Wan2.5 Image: limits and notes

Wan2.7 Image

Upload 1-9 images for editing mode; without images, operates as text-to-image.

Constraints

• Prompt max 5,000 characters
• Generation: 10-60s depending on resolution, image count, model variant, and thinking mode

Image inputs (editing mode)

• JPEG, PNG, BMP, or WEBP
• 240-8000 px per side
• Aspect ratio 1:8 to 8:1
• Max 20 MB per image

Capabilities

• Style transfer, object placement, scene blending, background replacement, multi-reference composition, interactive editing with bounding boxes
• Pro variant supports up to 4K output

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.

Wan2.5 Image

Text-to-image renders about 1.7 megapixels at the chosen aspect ratio; attach 1 to 3 images for editing and fusion at about 1 megapixel. Prompts up to 2000 characters.

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 Wan2.7 Image and Wan2.5 Image

Wan2.7 Image 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 wan2-7-image or wan2-5-image. 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": "wan2-7-image",
    "prompt": "Describe what you want Wan2.7 Image to generate."
  }'
