DeepSeek LLM

Overview

DeepSeekLLMService provides access to DeepSeek’s language models through an OpenAI-compatible interface. It inherits from OpenAILLMService and supports streaming responses, function calling, and context management with advanced reasoning capabilities.

Installation

To use DeepSeek services, install the required dependency:

uv add "pipecat-ai[deepseek]"

Prerequisites

DeepSeek Account Setup

Before using DeepSeek LLM services, you need:

DeepSeek Account: Sign up at DeepSeek Platform
API Key: Generate an API key from your account dashboard
Model Selection: Choose from available DeepSeek models with reasoning capabilities

Required Environment Variables

DEEPSEEK_API_KEY: Your DeepSeek API key for authentication

Configuration

str

required

DeepSeek API key for authentication. Raises ValueError when empty.

str

default:"https://api.deepseek.com/v1"

Base URL for DeepSeek API endpoint.

str

default:"None"

deprecated

Deprecated since 0.0.105, removed in 2.0.0. Use settings=DeepSeekLLMService.Settings(model=...) instead.

DeepSeekLLMService.Settings

default:"None"

Runtime-configurable settings. See Settings below.

Settings

Runtime-configurable settings passed via the settings constructor argument using DeepSeekLLMService.Settings(...). These can be updated mid-conversation with LLMUpdateSettingsFrame. See Service Settings for details.

DeepSeekLLMService.ThinkingConfig | None

default:"DeepSeekThinkingConfig(type='disabled')"

Thinking mode configuration. The service defaults this to disabled: DeepSeek’s V4 models otherwise run a reasoning pass before every answer, which delays the first spoken token. Set DeepSeekThinkingConfig(type="enabled") to turn it on, or None to leave the choice to DeepSeek’s own default.ThinkingConfig fields:

type (str): Thinking mode. DeepSeek’s V4 models think before answering unless "disabled" turns it off, which for real-time voice cuts the time to the first answer token. Values: "enabled", "disabled".

This service also inherits settings from OpenAILLMService. See OpenAI LLM Settings for the full parameter reference. The service defaults to model="deepseek-flash" when no model is specified.

Usage

Basic Setup

import os
from pipecat.services.deepseek.llm import DeepSeekLLMService

llm = DeepSeekLLMService(
    api_key=os.getenv("DEEPSEEK_API_KEY"),
    settings=DeepSeekLLMService.Settings(
        model="deepseek-flash",
    ),
)

With Custom Settings

from pipecat.services.deepseek.llm import DeepSeekLLMService

llm = DeepSeekLLMService(
    api_key=os.getenv("DEEPSEEK_API_KEY"),
    settings=DeepSeekLLMService.Settings(
        model="deepseek-flash",
        temperature=0.7,
        top_p=0.9,
        max_tokens=2048,
    ),
)

With Thinking Mode Enabled

from pipecat.services.deepseek.llm import DeepSeekLLMService

llm = DeepSeekLLMService(
    api_key=os.getenv("DEEPSEEK_API_KEY"),
    settings=DeepSeekLLMService.Settings(
        model="deepseek-flash",
        thinking=DeepSeekLLMService.ThinkingConfig(type="enabled"),
    ),
)

Notes

seed and max_completion_tokens are not sent by this service, so they have no effect. Use max_tokens instead.
run_inference() ignores response_schema with a warning, so the reply isn’t constrained to the schema.
