## SGLangModel

```python theme={"system"}
class SGLangModel(BaseModelBackend):
```

SGLang service interface.

**Parameters:**

* **model\_type** (Union\[ModelType, str]): Model for which a backend is created.
* **model\_config\_dict** (Optional\[Dict\[str, Any]], optional): A dictionary that will be fed into:obj:`openai.ChatCompletion.create()`. If :obj:`None`, :obj:`SGLangConfig().as_dict()` will be used. (default: :obj:`None`)
* **api\_key** (Optional\[str], optional): The API key for authenticating with the model service. SGLang doesn't need API key, it would be ignored if set. (default: :obj:`None`)
* **url** (Optional\[str], optional): The url to the model service. If not provided, :obj:`"http://127.0.0.1:30000/v1"` will be used. (default: :obj:`None`)
* **token\_counter** (Optional\[BaseTokenCounter], optional): Token counter to use for the model. If not provided, :obj:`OpenAITokenCounter( ModelType.GPT_4O_MINI)` will be used. (default: :obj:`None`)
* **timeout** (Optional\[float], optional): The timeout value in seconds for API calls. If not provided, will fall back to the MODEL\_TIMEOUT environment variable or default to 180 seconds. (default: :obj:`None`)
* **max\_retries** (int, optional): Maximum number of retries for API calls. (default: :obj:`3`)
* **client** (Optional\[Any], optional): A custom synchronous OpenAI-compatible client instance. If provided, this client will be used instead of creating a new one. Note: When using custom clients with SGLang, server auto-start features will be disabled. (default: :obj:`None`)
* **async\_client** (Optional\[Any], optional): A custom asynchronous OpenAI-compatible client instance. If provided, this client will be used instead of creating a new one. (default: :obj:`None`) \*\*kwargs (Any): Additional arguments to pass to the client initialization. Ignored if custom clients are provided.
