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?"

Mode	Best For	Speed	Quality
max	Final production images, print materials, important projects	Slower	Highest
eco	Quick previews, batch testing, web thumbnails	Faster	Good

Multi-Turn Upscaling Workflow

Use session_id to iterate on upscaling results:

# Initial upscale
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Upscale this photo 4x for print"}],
    "model": "eachsense/beta",
    "stream": true,
    "image_urls": ["https://example.com/photo.jpg"],
    "session_id": "upscale-project-001"
  }'

# Request adjustments
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "The result looks good but can you also apply face enhancement and reduce noise?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "upscale-project-001"
  }'

# Request different scale
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Actually I need 8x for a larger print. Can you upscale it further?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "upscale-project-001"
  }'

Error Handling

Error	Cause	Solution
Failed to create prediction: HTTP 422	Insufficient balance	Top up at eachlabs.ai
Image too large	Source image exceeds maximum dimensions	Resize source image before upscaling
Timeout	Large scale factors take longer	Set client timeout to minimum 10 minutes
Unsupported format	Invalid image format	Use JPEG, PNG, or WebP input
