# Persona Slots

Persona slots are the visual knowledge library of personas.

## Persona Slots

Persona slots are the visual knowledge library of personas.

<table><thead><tr><th width="201">Slot Number</th><th></th></tr></thead><tbody><tr><td>1-6</td><td>Visual training slots from 1 to 6. <br>This slots make fine-tuning for your persona's visual style.<br><strong>Note:</strong> <strong><code>1</code></strong> is master slot and using for <strong>Style Transfer</strong> with <strong><code>pid</code></strong>, it is <strong><code>style_transfer</code></strong> parameter for <a href="/api/luw.ai-api-documentation/ai-models.md">generators</a>. If you pass <strong><code>style_transfer=persona</code></strong> to the generate endpoint, it will use Slot 1 for Style Transfer</td></tr><tr><td>7</td><td>Main image for persona to manipulate, it is <strong><code>image</code></strong> parameter for <a href="/api/luw.ai-api-documentation/ai-models.md">generators</a></td></tr></tbody></table>

**Curl Example**

```bash
# Store image in slot 1 (style reference)
curl -X POST https://api.luw.ai/v2/personas/123/trains \
-H "Authorization: Bearer LUW_API_TOKEN" \
-d "photo=https://example.com/style.jpg" \
-d "slot=1"

# Store image in slot 7 (main image)
curl -X POST https://api.luw.ai/v2/personas/123/trains \
-H "Authorization: Bearer LUW_API_TOKEN" \
-d "photo=https://example.com/room.jpg" \
-d "slot=7"
```

**Using Slots in Generation**

To use slots in generation, provide the persona ID using the `pid` parameter:

```bash
curl -X POST https://api.luw.ai/v2/generate \
-H "Authorization: Bearer LUW_API_TOKEN" \
-d "model=interior" \
-d "pid=123" \
-d "style_transfer=persona"  # Uses slot 1 as style reference
```

This will automatically:

* Use slot 1 for style reference if `style_transfer=persona`
* Use slot 7 as the input image if no explicit image URL provided

When configuring persona slots in Interior AI, providing a `pid` (Persona ID) parameter eliminates the need to specify the `image` and `style_transfer` parameters.

For instance, in the Fluw implementation, once you establish a persona and assign an image to slot 7, subsequent operations require only the `pid` parameter. The system will automatically utilize the slot's designated image as the starting frame for video generation, with processing continuing from that initial state. \

This persona slot functionality is not unique to Interior AI, or Fluw - it can be implemented across all Luw\.ai [generators](/api/luw.ai-api-documentation/ai-models.md), allowing for consistent style application and streamlined parameter management.
