## Quick start

| Parameter | Value |
|-----------|-------|
| Trigger | `retro rainbow cosmos style` |
| Recommended LoRA scale | `1.0` to `1.25` |
| Base model | `krea/Krea-2-Turbo` |
| Trained on | [fal-ai/krea-2-trainer](https://fal.ai/models/fal-ai/krea-2-trainer) |

## Inference on fal

### Python
```python
import fal_client

result = fal_client.subscribe(
    "fal-ai/krea-2/turbo/lora",
    arguments={
        "prompt": "a lighthouse on a rocky cliff. retro rainbow cosmos style",
        "loras": [{"path": "https://huggingface.co/ilkerzgi/krea-2-retro-rainbow-cosmos-lora/resolve/main/retro-rainbow-cosmos.safetensors", "scale": 1.0}],
        "image_size": {"width": 1024, "height": 1280},
    },
)
print(result["images"][0]["url"])
```

### JavaScript
```js
import { fal } from "@fal-ai/client";

const { data } = await fal.subscribe("fal-ai/krea-2/turbo/lora", {
  input: {
    prompt: "a lighthouse on a rocky cliff. retro rainbow cosmos style",
    loras: [{ path: "https://huggingface.co/ilkerzgi/krea-2-retro-rainbow-cosmos-lora/resolve/main/retro-rainbow-cosmos.safetensors", scale: 1.0 }],
    image_size: { width: 1024, height: 1280 },
  },
});
console.log(data.images[0].url);
```

## Train your own on fal

Every LoRA in this series is trained on [`fal-ai/krea-2-trainer`](https://fal.ai/models/fal-ai/krea-2-trainer) (100 steps, learning rate 3.5e-4). Train your own style from 4 to 10 reference images:

```python
import fal_client

result = fal_client.subscribe(
    "fal-ai/krea-2-trainer",
    arguments={
        "images_data_url": "https://.../your-dataset.zip",
        "trigger_phrase": "retro rainbow cosmos style",
        "steps": 100,
        "learning_rate": 0.00035,
    },
)
print(result)
```
