## VolcanoModel

```python theme={"system"}
class VolcanoModel(OpenAICompatibleModel):
```

Volcano Engine API in a unified OpenAICompatibleModel 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 the API call. If :obj:`None`, :obj:`{}` will be used. (default: :obj:`None`)
* **api\_key** (Optional\[str], optional): The API key for authenticating with the Volcano Engine service. (default: :obj:`None`)
* **url** (Optional\[str], optional): The url to the Volcano Engine service. (default: :obj:`https://ark.cn-beijing.volces.com/api/v3`)
* **token\_counter** (Optional\[BaseTokenCounter], optional): Token counter to use for the model. If not provided, :obj:`OpenAITokenCounter` 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`) \*\*kwargs (Any): Additional arguments to pass to the client initialization.

### **init**

```python theme={"system"}
def __init__(
    self,
    model_type: Union[ModelType, str],
    model_config_dict: Optional[Dict[str, Any]] = None,
    api_key: Optional[str] = None,
    url: Optional[str] = None,
    token_counter: Optional[BaseTokenCounter] = None,
    timeout: Optional[float] = None,
    max_retries: int = 3,
    **kwargs: Any
):
```

<a id="camel.models.volcano_model.VolcanoModel._inject_reasoning_content" />

### \_inject\_reasoning\_content

```python theme={"system"}
def _inject_reasoning_content(self, messages: List[OpenAIMessage]):
```

Inject the last reasoning\_content into assistant messages.

For Volcano Engine's doubao-seed models with deep thinking enabled,
the reasoning\_content from the model response needs to be passed back
in subsequent requests for proper context management.

**Parameters:**

* **messages**: The original messages list.

**Returns:**

Messages with reasoning\_content added to the last assistant
message that has tool\_calls.

<a id="camel.models.volcano_model.VolcanoModel._extract_reasoning_content" />

### \_extract\_reasoning\_content

```python theme={"system"}
def _extract_reasoning_content(self, response: ChatCompletion):
```

Extract reasoning\_content from the model response.

**Parameters:**

* **response**: The model response.

**Returns:**

The reasoning\_content if available, None otherwise.

<a id="camel.models.volcano_model.VolcanoModel.run" />

### run

```python theme={"system"}
def run(
    self,
    messages: List[OpenAIMessage],
    response_format: Optional[Type[BaseModel]] = None,
    tools: Optional[List[Dict[str, Any]]] = None
):
```

Runs inference of Volcano Engine chat completion.

Overrides the base run method to inject reasoning\_content from
previous responses into subsequent requests, as required by
Volcano Engine's doubao-seed models with deep thinking enabled.

**Parameters:**

* **messages**: Message list with the chat history in OpenAI API format.
* **response\_format**: The format of the response.
* **tools**: The schema of the tools to use for the request.

**Returns:**

ChatCompletion in the non-stream mode, or
Stream\[ChatCompletionChunk] in the stream mode.
