# DecartProvider

> Provider interface for creating Decart image and video models

## Interface

```typescript theme={null}
interface DecartProvider extends ProviderV2 {
  image(modelId: DecartImageModelId): ImageModelV2;
  imageModel(modelId: DecartImageModelId): ImageModelV2;
  video(modelId: DecartVideoModelId): Experimental_VideoModelV3;
  videoModel(modelId: DecartVideoModelId): Experimental_VideoModelV3;
}
```

The `DecartProvider` interface extends the AI SDK's `ProviderV2` and provides methods to instantiate image and video generation models.

## Methods

### image()

```typescript theme={null}
image(modelId: DecartImageModelId): ImageModelV2
```

Creates an image generation model instance.

<ParamField path="modelId" type="DecartImageModelId" required>
  The identifier of the image model to use.

  See [Image Models](/api/image-models) for available model IDs.
</ParamField>

<ResponseField name="return" type="ImageModelV2">
  An image model instance compatible with AI SDK's `generateImage()` function.
</ResponseField>

### imageModel()

```typescript theme={null}
imageModel(modelId: DecartImageModelId): ImageModelV2
```

Alias for `image()`. Creates an image generation model instance.

<ParamField path="modelId" type="DecartImageModelId" required>
  The identifier of the image model to use.
</ParamField>

<ResponseField name="return" type="ImageModelV2">
  An image model instance compatible with AI SDK's `generateImage()` function.
</ResponseField>

### video()

```typescript theme={null}
video(modelId: DecartVideoModelId): Experimental_VideoModelV3
```

Creates a video generation model instance.

<ParamField path="modelId" type="DecartVideoModelId" required>
  The identifier of the video model to use.

  See [Video Models](/api/video-models) for available model IDs.
</ParamField>

<ResponseField name="return" type="Experimental_VideoModelV3">
  A video model instance compatible with AI SDK's `experimental_generateVideo()` function.
</ResponseField>

### videoModel()

```typescript theme={null}
videoModel(modelId: DecartVideoModelId): Experimental_VideoModelV3
```

Alias for `video()`. Creates a video generation model instance.

<ParamField path="modelId" type="DecartVideoModelId" required>
  The identifier of the video model to use.
</ParamField>

<ResponseField name="return" type="Experimental_VideoModelV3">
  A video model instance compatible with AI SDK's `experimental_generateVideo()` function.
</ResponseField>

## Examples

### Creating an Image Model

```typescript theme={null}
import { createDecart } from '@decartai/ai-sdk-provider';
import { generateImage } from 'ai';

const decart = createDecart();

const { image } = await generateImage({
  model: decart.image('lucy-pro-t2i'),
  prompt: 'A serene mountain landscape'
});
```

### Creating a Video Model

```typescript theme={null}
import { createDecart } from '@decartai/ai-sdk-provider';
import { experimental_generateVideo } from 'ai';

const decart = createDecart();

const { video } = await experimental_generateVideo({
  model: decart.video('lucy-pro-t2v'),
  prompt: 'Waves crashing on a beach at sunset'
});
```

### Using Both Methods

```typescript theme={null}
import { createDecart } from '@decartai/ai-sdk-provider';

const decart = createDecart();

// These are equivalent
const imageModel1 = decart.image('lucy-pro-t2i');
const imageModel2 = decart.imageModel('lucy-pro-t2i');

// These are equivalent
const videoModel1 = decart.video('lucy-pro-t2v');
const videoModel2 = decart.videoModel('lucy-pro-t2v');
```

## Unsupported Methods

The Decart provider does not support language or text embedding models. Calling these methods will throw a `NoSuchModelError`:

* `languageModel(modelId: string)` - Not supported
* `textEmbeddingModel(modelId: string)` - Not supported
