Best Practices

Reference Photo Guidelines

• Quantity: Provide 3-10 reference photos for best results
• Angles: Include front, 3/4, and profile views when possible
• Lighting: Use well-lit photos without harsh shadows
• Resolution: Higher resolution photos produce better twins
• Consistency: Photos should show the same person at similar age
• Expressions: Include variety for expressive twin generation

Quality Optimization

• Mode Selection: Use max for final assets, eco for rapid prototyping
• Iterative Refinement: Use session_id to refine twins across multiple requests
• Specific Details: Describe exact requirements for lighting, background, expression
• Format Specification: Always specify aspect ratio and intended use

Identity Consistency

• Session Continuity: Use same session_id for all variations of one twin
• Reference Anchoring: Include original photos when requesting variations
• Style Lock: Describe consistent elements (lighting, background) across requests

Mode Selection

Ask your users before generating:

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

Multi-Turn Twin Development

Use session_id to iteratively develop and refine digital twins:

# Initial twin generation
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": "Create a digital twin from these photos for corporate communications",
    "image_urls": ["https://example.com/ceo-photo1.jpg", "https://example.com/ceo-photo2.jpg"],
    "mode": "max",
    "session_id": "ceo-digital-twin"
  }'

# Refine based on feedback
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": "Make the expression slightly more serious and add subtle rim lighting for more dimension",
    "session_id": "ceo-digital-twin"
  }'

# Generate variations
curl -X POST https://sense.eachlabs.run/chat \
