# Flux Kontext Dev

Edit images using Flux Kontext with prompt-based instructions. Supports acceleration modes, configurable inference steps, guidance scale, multiple output formats, and flexible resolution modes.

## Quick Start

> Requires an each::labs API key. Get one at [eachlabs.ai](https://eachlabs.ai).

```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "flux-kontext-dev",
    "version": "0.0.1",
    "input": {
      "image_url": "https://example.com/photo.jpg",
      "prompt": "Change the person's shirt color to bright red",
      "num_images": 1,
      "output_format": "jpeg"
    }
  }'
```

| acceleration | string | none | Generation speed. enum: none, regular, high |
| enable_safety_checker | boolean | true | If set to true, the safety checker will be enabled |
| enhance_prompt | boolean | false | Whether to enhance the prompt for better results |
| guidance_scale | number | 2.5 | CFG scale for prompt adherence |
| image_url | string | | The URL of the image to edit |

## Examples

**Object replacement with acceleration:**
```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "flux-kontext-dev",
    "version": "0.0.1",
    "input": {
      "image_url": "https://example.com/desk-setup.jpg",
      "prompt": "Replace the laptop with a vintage typewriter",
      "acceleration": "regular",
      "num_images": 1,
      "guidance_scale": 3.0,
      "output_format": "png"
    }
  }'
```

**Style transformation with multiple outputs:**
```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "flux-kontext-dev",
    "version": "0.0.1",
    "input": {
      "image_url": "https://example.com/cityscape.jpg",
      "prompt": "Transform into a Studio Ghibli anime art style with soft pastel colors",
      "num_images": 3,
      "acceleration": "high",
      "enhance_prompt": true,
      "resolution_mode": "16:9",
      "seed": "12345"
    }
  }'
```
