```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "sana",
    "version": "0.0.1",
    "input": {
      "prompt": "a cyberpunk cat with a neon sign that says Sana",
      "width": 1024,
      "height": 1024,
      "num_inference_steps": 18,
      "guidance_scale": 5
    }
  }'
```

## Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| guidance_scale | number | 5 | Classifier-free guidance scale |
| height | integer | 1024 | Height of output image |
| negative_prompt | string | - | Specify things to not see in the output |
| num_inference_steps | integer | 18 | Number of denoising steps |
| pag_guidance_scale | number | 2 | PAG Guidance scale |
| prompt | string | a cyberpunk cat with a neon sign... | Input prompt |
| seed | integer | - | Random seed. Leave blank to randomize |
| width | integer | 1024 | Width of output image |
