# Juggernaut Flux Lora

Generate high-quality images using the Juggernaut Flux model with optional LoRA support for style customization. Fine-tune output with guidance scale, inference steps, and custom seeds.

## Quick Start

```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \

    "version": "0.0.1",
    "input": {
      "prompt": "A hyper-realistic portrait of a woman in golden hour light, shallow depth of field",
      "image_size": "portrait_4_3",
      "num_images": 1,
      "guidance_scale": 3.5,

  }'
```

## Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `enable_safety_checker` | boolean | `true` | If set to true, the safety checker will be enabled |
| `guidance_scale` | number | `3.5` | CFG scale controlling how closely the output matches the prompt |

| `loras` | array | `false` | The LoRAs to use for image generation. Supports multiple LoRAs with custom weights |
| `num_images` | integer | `1` | The number of images to generate |
| `num_inference_steps` | integer | `28` | The number of inference steps to perform |
| `output_format` | string | `jpeg` | The format of the generated image. Options: `jpeg`, `png` |
| `prompt` | string | (empty) | The prompt to generate an image from |
| `seed` | integer | (empty) | Random seed for reproducible generation |

## Output
