llm

DeepSeek LLM service implementation using OpenAI-compatible interface.

Bases: OpenAILLMSettings

Settings for DeepSeekLLMService.

class pipecat.services.deepseek.llm.DeepSeekLLMService(*, api_key: str, base_url: str = 'https://api.deepseek.com/v1', model: str | None = None, settings: DeepSeekLLMSettings | None = None, **kwargs)[source]

Bases: OpenAILLMService

A service for interacting with DeepSeek’s API using the OpenAI-compatible interface.

This service extends OpenAILLMService to connect to DeepSeek’s API endpoint while maintaining full compatibility with OpenAI’s interface and functionality.

supports_developer_role = False

Whether this service’s API supports the “developer” message role.

OpenAI’s native API supports it, but some OpenAI-compatible services (e.g. Cerebras) do not. Subclasses that don’t support it should set this to False, which causes the adapter to convert “developer” messages to “user” messages before sending them to the API.

__init__(*, api_key: str, base_url: str = 'https://api.deepseek.com/v1', model: str | None = None, settings: DeepSeekLLMSettings | None = None, **kwargs)[source]

Initialize the DeepSeek LLM service.

Parameters:

  • api_key – The API key for accessing DeepSeek’s API.

  • base_url – The base URL for DeepSeek API. Defaults to “https://api.deepseek.com/v1”.

  • model –

    The model identifier to use. Defaults to “deepseek-chat”.

    Deprecated since version 0.0.105: Use settings=DeepSeekLLMService.Settings(model=...) instead.

  • settings – Runtime-updatable settings. When provided alongside deprecated parameters, settings values take precedence.

  • **kwargs – Additional keyword arguments passed to OpenAILLMService.

create_client(api_key=None, base_url=None, **kwargs)[source]

Create OpenAI-compatible client for DeepSeek API endpoint.

Parameters:

  • api_key – The API key for authentication. If None, uses instance default.

  • base_url – The base URL for the API. If None, uses instance default.

  • **kwargs – Additional keyword arguments for client configuration.

Returns:

An OpenAI-compatible client configured for DeepSeek’s API.
