Multi-Turn Creative Iteration

Use session_id to refine and iterate on face morphs:

# Initial morph
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Morph these two faces together with a 50/50 blend",
    "image_urls": [
      "https://example.com/face-a.jpg",
      "https://example.com/face-b.jpg"
    ],
    "session_id": "morph-project-001"
  }'

# Adjust the blend ratio
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Adjust the blend to be 70% first face and 30% second face",
    "session_id": "morph-project-001"
  }'

# Request specific feature adjustments
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Keep the eyes from the first face but use the jawline from the second face",
    "session_id": "morph-project-001"
  }'

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Best Practices

Input Image Quality

• Resolution: Use high-resolution face photos (at least 512x512)
• Lighting: Consistent lighting across input images produces better blends
• Face Position: Front-facing photos with similar angles work best
• Background: Clean backgrounds help isolate facial features

Morph Quality Tips

• Similar poses: Input faces with similar head positions morph better
• Clear features: Avoid obscured faces (sunglasses, hands covering face)
• Age consistency: For family predictions, consider parent ages at time of photos
• Multiple runs: Try different prompts to find the best blend style

Animation Considerations

• Frame count: More frames create smoother transitions
• Duration: 2-5 seconds is ideal for morph animations
• Loop-friendly: Request seamless loops for social media use

Prompt Tips for Face Morphing

When creating face morphs, include these details in your prompt:

1. Blend Ratio: Specify the percentage blend (50/50, 70/30, etc.)
2. Feature Focus: Which features to take from which face
3. Output Type: Image or video animation
4. Style: Realistic, artistic, exaggerated, etc.
5. Age Target: For child predictions, specify desired age

Example Prompt Structure

"[Action] these faces with [blend ratio].
Take [features] from the first face and [features] from the second.
Output as [image/video]. Make it look [style descriptor]."
