# Flux Schnell

Generate images quickly from text prompts with Flux Schnell. Optimized for speed with just 4 denoising steps, making it ideal for rapid prototyping and real-time applications.

## 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-schnell",
    "version": "0.0.1",
    "input": {
      "prompt": "a cozy reading nook with floor-to-ceiling bookshelves, warm afternoon light streaming through a window",
      "aspect_ratio": "1:1",
      "num_inference_steps": 4,
      "output_format": "webp"
    }
  }'
```
