## Pricing

Billing is calculated per second of video generated. For 360p, your request will cost **$0.025** per second without audio and **$0.035** per second with audio. For 540p, it will cost **$0.035** per second without audio and **$0.045** per second with audio. For 720p, it will cost **$0.045** per second without audio and **$0.060** per second with audio.

## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

The API accepts the following input parameters:


- **`prompt`** (`string`, _required_):
  Text prompt for the video generation. Limited to 2048 UTF-8 encoded bytes. Because the limit counts bytes rather than characters, emoji and non-Latin or accented characters (which use multiple bytes each) can push a visually short prompt over the cap.
  - Examples: "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"

- **`aspect_ratio`** (`AspectRatioEnum`, _optional_):
  The aspect ratio of the generated video Default value: `"16:9"`
  - Default: `"16:9"`
  - Options: `"16:9"`, `"4:3"`, `"1:1"`, `"3:4"`, `"9:16"`, `"2:3"`, `"3:2"`, `"21:9"`

- **`resolution`** (`ResolutionEnum`, _optional_):
  The resolution of the generated video Default value: `"720p"`
  - Default: `"720p"`
  - Options: `"360p"`, `"540p"`, `"720p"`, `"1080p"`

- **`duration`** (`integer`, _optional_):
  The duration of the generated video in seconds. v6 supports values from 1 to 15 seconds Default value: `5`
  - Default: `5`
  - Range: `1` to `15`

- **`negative_prompt`** (`string`, _optional_):
  Negative prompt to be used for the generation. Limited to 2048 UTF-8 encoded bytes. Because the limit counts bytes rather than characters, emoji and non-Latin or accented characters (which use multiple bytes each) can push a visually short prompt over the cap. Default value: `""`
  - Default: `""`
  - Examples: "blurry, low quality, low resolution, pixelated, noisy, grainy, out of focus, poorly lit, poorly exposed, poorly composed, poorly framed, poorly cropped, poorly color corrected, poorly color graded"

- **`style`** (`Enum`, _optional_):
  The style of the generated video
  - Options: `"anime"`, `"3d_animation"`, `"clay"`, `"comic"`, `"cyberpunk"`

- **`seed`** (`integer`, _optional_):
  The same seed and the same prompt given to the same version of the model
  will output the same video every time.

- **`generate_audio_switch`** (`boolean`, _optional_):
  Enable audio generation (BGM, SFX, dialogue)
  - Default: `false`

- **`generate_multi_clip_switch`** (`boolean`, _optional_):
  Enable multi-clip generation with dynamic camera changes
  - Default: `false`

- **`thinking_type`** (`Enum`, _optional_):
  Prompt optimization mode: 'enabled' to optimize, 'disabled' to turn off, 'auto' for model decision
  - Options: `"enabled"`, `"disabled"`, `"auto"`

- **`enable_safety_checker`** (`boolean`, _optional_):
  Authorized callers may set false to request relaxed screening. Default value: `true`
  - Default: `true`



**Required Parameters Example**:

```json
{
  "prompt": "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
}
```

}
```


### Output Schema

The API returns the following output format:

## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/pixverse/v6/text-to-video \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "prompt": "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
   }'
```

### Python

Ensure you have the Python client installed:

```bash
pip install fal-client
```

Then use the API client to make requests:

```python
import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "pixverse/v6/text-to-video",
    arguments={
        "prompt": "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("pixverse/v6/text-to-video", {
  input: {
    prompt: "Epic low-cut camera capture of a girl clad in ultraviolet threads, Peter Max art style depiction, luminous diamond skin glistening under a vast moon's radiance, embodied in a superhuman flight among mystical ruins, symbolizing a deity's ritual ascent, hyper-detailed"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```


## Deploy your own model

To run your own weights, a fine-tune or a custom pipeline on the GPUs that serve this API, deploy it on fal Serverless. GPUs from H100 (80GB) to B300 (288GB), billed per second; an H100 is $4.50/h list, as low as $2.49/h. Prices, GPU specs and deploy steps: [fal Serverless](https://fal.ai/serverless.md).
