    "session_id": "batch-upscale-products",
    "mode": "max"
  }'

# Second image (same session maintains settings)
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": "Upscale this next product image using the same settings as before.",

    "session_id": "batch-upscale-products"
  }'

Best Practices

Choosing Scale Factor

• 2x: Sufficient for most web and social media use cases
• 4x: Standard for print quality (300 DPI equivalent)
• 8x+: Only for large format where viewing distance is greater

Quality Tips

• Source Quality Matters: Higher quality input produces better upscaled output
• File Format: Use PNG or high-quality JPEG (90%+) as input when possible
• Face Enhancement: Enable only for images with human faces
• Noise Reduction: Use aggressively for low-light or heavily compressed images

Output Considerations

• File Size: Higher scale factors produce significantly larger files
• Processing Time: 8x and 16x upscaling takes longer - be patient
• Viewing Distance: Large format prints are viewed from distance; extreme detail isn't always necessary

Prompt Tips for Image Upscaling

When requesting upscaling, include these details in your prompt:

1. Scale Factor: Specify 2x, 4x, 8x, or 16x
2. Use Case: Web, print, large format display
3. Image Type: Photo, AI art, product shot, portrait
4. Special Requirements: Face enhancement, noise reduction, artifact removal
5. Output Intent: Final use case helps optimize processing

Example Prompt Structure

"Upscale this [image type] [scale factor] for [use case].
[Special requirements like face enhancement or noise reduction].
[Additional context about the source image quality or intended output]."

Mode Selection

Ask your users before processing:

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

Multi-Turn Upscaling Workflow

Use session_id to iterate on upscaling results:

# Initial upscale
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": "Upscale this photo 4x for print",
    "image_urls": ["https://example.com/photo.jpg"],
    "session_id": "upscale-project-001"
  }'

# Request 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": "The result looks good but can you also apply face enhancement and reduce noise?",
    "session_id": "upscale-project-001"
  }'

# Request different scale
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": "Actually I need 8x for a larger print. Can you upscale it further?",
    "session_id": "upscale-project-001"
  }'
