Image Upscaling

Image Upscaling

Enhance image resolution with AI-powered upscaling using each::sense — the intelligent AI agent that automatically selects the best model for your request.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

Using curl

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Upscale this image to 4x resolution. Enhance sharpness and detail while keeping the original look natural. Remove any compression artifacts."},
              {"type": "image_url", "image_url": {"url": "https://example.com/low-res-photo.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Using Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{
        "role": "user",
        "content": "Upscale this image to 4x resolution. Enhance sharpness and detail while keeping the original look natural. Remove any compression artifacts."
    }],
    # Images are included in the message content array above
)

print(response.choices[0].message.content)

Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

Streaming

Set "stream": true for real-time Server-Sent Events (SSE) responses, or "stream": false to receive the complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Upscaling Scenarios

Examples

Photo for Print

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Upscale this photograph for large-format printing. Increase resolution while preserving natural skin textures, fine hair detail, and fabric weave. Do not over-sharpen or add artificial detail."},
              {"type": "image_url", "image_url": {"url": "https://example.com/portrait-web.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Digital Art Upscaling

curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Upscale this digital illustration to high resolution. Preserve the clean line art, flat color areas, and intentional brush strokes. Keep the artistic style intact without adding photorealistic detail."},
              {"type": "image_url", "image_url": {"url": "https://example.com/illustration-small.png"}}
            ]
          }
    ],
    "stream": false
  }'

Old Photo Restoration + 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" \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": [
              {"type": "text", "text": "Upscale and restore this old scanned photograph. Remove film grain and scanning artifacts. Enhance facial details and sharpness. Correct faded colors to look natural. Output at 4x the original resolution."},
              {"type": "image_url", "image_url": {"url": "https://example.com/old-family-photo-scan.jpg"}}
            ]
          }
    ],
    "stream": false
  }'

Prompt Tips

• Specify the goal: "for printing," "for web," or "for a presentation" helps the model optimize
• Mention artifact handling: "Remove JPEG compression artifacts" for heavily compressed sources
• Preserve style intent: For artwork, say "Keep the artistic style" to prevent unwanted photorealism
• Control sharpening: "Do not over-sharpen" prevents artificial haloing effects
• Face priority: "Focus on facial detail" when portraits are the main subject
