# DeepSeek

> Integrate DeepSeek models with Prisma AIRS AI Gateway

The AI Gateway provides a robust and secure gateway to integrate various Large Language Models (LLMs) into applications, including DeepSeek's models.

With the AI Gateway, take advantage of features like fast AI gateway access, observability, prompt management, and more, while securely managing API keys through [Model Catalog](/docs/aigw/product/model-catalog).

## Quick Start

Get DeepSeek working in 3 steps:

<CodeGroup>
  ```sh cURL icon="square-terminal" theme={"system"}
  # 1. Add @deepseek provider in model catalog
  # 2. Use it:

  curl https://aigw.portkey.ai/v1/chat/completions \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer $PORTKEY_API_KEY" \
    -d '{
      "model": "@deepseek/deepseek-chat",
      "messages": [
        { "role": "user", "content": "Say this is a test" }
      ]
    }'
  ```

  ```python OpenAI Py icon="python" theme={"system"}
  from openai import OpenAI

  # 1. Install: pip install openai
  # 2. Add @deepseek provider in model catalog
  # 3. Use it:

  client = OpenAI(
      api_key="PORTKEY_API_KEY",  # AI Gateway API key
      base_url="https://aigw.portkey.ai/v1"
  )

  response = client.chat.completions.create(
      model="@deepseek/deepseek-chat",
      messages=[{"role": "user", "content": "Say this is a test"}]
  )

  print(response.choices[0].message.content)
  ```

  ```js OpenAI JS icon="square-js" theme={"system"}
  import OpenAI from "openai"

  // 1. Install: npm install openai
  // 2. Add @deepseek provider in model catalog
  // 3. Use it:

  const client = new OpenAI({
      apiKey: "PORTKEY_API_KEY",  // AI Gateway API key
      baseURL: "https://aigw.portkey.ai/v1"
  })

  const response = await client.chat.completions.create({
      model: "@deepseek/deepseek-chat",
      messages: [{ role: "user", content: "Say this is a test" }]
  })

  console.log(response.choices[0].message.content)
  ```
</CodeGroup>

<Note>
  **Tip:** You can also send `x-portkey-provider: @deepseek` as a header and use just `model="deepseek-chat"` in the request.
</Note>

## Add Provider in Model Catalog

1. Go to [**Model Catalog → Add Provider**](https://stratacloudmanager.paloaltonetworks.com/)
2. Select **DeepSeek**
3. Choose existing credentials or create new by entering your [DeepSeek API key](https://platform.deepseek.com/api_keys)
4. Name your provider (e.g., `deepseek-prod`)

## Advanced Features

### Multi-round Conversations

DeepSeek supports multi-turn conversations where context is maintained across messages:

### JSON Output

Force structured JSON responses from DeepSeek models:

## Tool Calling

DeepSeek supports tool calling (function calling) on the `deepseek-chat` model. Pass `tools` and optionally `tool_choice` in your request:

## Reasoning (deepseek-reasoner)

The `deepseek-reasoner` model supports chain-of-thought reasoning. Use the `reasoning_effort` parameter to control reasoning behavior:

When streaming, `reasoning_content` is included in the delta for `deepseek-reasoner` responses.

## Managing DeepSeek Prompts

Manage all prompt templates to DeepSeek in the Prompt Library. All current DeepSeek models are supported, and you can easily test different prompts.

Call the `POST /v1/prompts/{promptId}/completions` endpoint to use the prompt in an application.

## Supported Endpoints

* Chat Completions
* Streaming Chat Completions
