## 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_):
  The text prompt used to generate the image
  - Examples: "A trendy restaurant with a digital menu board displaying \"Seedream 4.0 is available on fal\" in elegant script, with diners enjoying their meals."

- **`image_size`** (`ImageSize | Enum`, _optional_):
  The size of the generated image. Total pixels must be between 960x960 and 4096x4096.
  - Default: `{"height":2048,"width":2048}`
  - One of: ImageSize | Enum
  - Examples: {"height":4096,"width":4096}

- **`num_images`** (`integer`, _optional_):
  Number of separate model generations to be run with the prompt. Default value: `1`
  - Default: `1`
  - Range: `1` to `6`

- **`max_images`** (`integer`, _optional_):
  If set to a number greater than one, enables multi-image generation. The model will potentially return up to `max_images` images every generation, and in total, `num_images` generations will be carried out. In total, the number of images generated will be between `num_images` and `max_images*num_images`. Default value: `1`
  - Default: `1`
  - Range: `1` to `6`

- **`seed`** (`integer`, _optional_):
  Random seed to control the stochasticity of image generation.

- **`sync_mode`** (`boolean`, _optional_):
  If `True`, the media will be returned as a data URI and the output data won't be available in the request history.
  - Default: `false`

- **`enable_safety_checker`** (`boolean`, _optional_):
  If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked. Default value: `true`
  - Default: `true`
  - Examples: true

- **`enhance_prompt_mode`** (`EnhancePromptModeEnum`, _optional_):
  The mode to use for enhancing prompt enhancement. Standard mode provides higher quality results but takes longer to generate. Fast mode provides average quality results but takes less time to generate. Default value: `"standard"`
  - Default: `"standard"`
  - Options: `"standard"`, `"fast"`



**Required Parameters Example**:

```json
{
  "prompt": "A trendy restaurant with a digital menu board displaying \"Seedream 4.0 is available on fal\" in elegant script, with diners enjoying their meals."
}
```

```


### Output Schema

The API returns the following output format:

- **`images`** (`list<Image>`, _required_):
  Generated images
  - Array of Image
  - Examples: [{"url":"https://storage.googleapis.com/falserverless/example_outputs/seedream4_t2i_output.png"}]

- **`seed`** (`integer`, _required_):
  Seed used for generation
  - Examples: 746406749



**Example Response**:

```json
{
  "images": [
    {
      "url": "https://storage.googleapis.com/falserverless/example_outputs/seedream4_t2i_output.png"
    }
  ],
  "seed": 746406749
}
```


## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/fal-ai/bytedance/seedream/v4/text-to-image \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "prompt": "A trendy restaurant with a digital menu board displaying \"Seedream 4.0 is available on fal\" in elegant script, with diners enjoying their meals."
   }'
```

### 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(
    "fal-ai/bytedance/seedream/v4/text-to-image",
    arguments={
        "prompt": "A trendy restaurant with a digital menu board displaying \"Seedream 4.0 is available on fal\" in elegant script, with diners enjoying their meals."
    },
    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("fal-ai/bytedance/seedream/v4/text-to-image", {
  input: {
    prompt: "A trendy restaurant with a digital menu board displaying \"Seedream 4.0 is available on fal\" in elegant script, with diners enjoying their meals."
  },
  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);
```
