# DeepSeek

[DeepSeek ↗](https://www.deepseek.com/) helps you build quickly with DeepSeek's advanced AI models.

## Endpoint

```
https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/deepseek
```

## Prerequisites

When making requests to DeepSeek, ensure you have the following:

* Your AI Gateway Account ID.
* Your AI Gateway gateway name.
* An active DeepSeek AI API token.
* The name of the DeepSeek AI model you want to use.

## URL structure

Your new base URL will use the data above in this structure:

`https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/deepseek/`.

You can then append the endpoint you want to hit, for example: `chat/completions`.

So your final URL will come together as:

`https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/deepseek/chat/completions`.

## Examples

### cURL

Example fetch request

```
curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/deepseek/chat/completions \ --header 'content-type: application/json' \ --header 'Authorization: Bearer DEEPSEEK_TOKEN' \ --data '{    "model": "deepseek-chat",    "messages": [        {            "role": "user",            "content": "What is Cloudflare?"        }    ]}'
```

### Use DeepSeek with JavaScript

If you are using the OpenAI SDK, you can set your endpoint like this:

JavaScript

```
import OpenAI from "openai";
const openai = new OpenAI({  apiKey: env.DEEPSEEK_TOKEN,  baseURL:    "https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/deepseek",});
try {  const chatCompletion = await openai.chat.completions.create({    model: "deepseek-chat",    messages: [{ role: "user", content: "What is Cloudflare?" }],  });
  const response = chatCompletion.choices[0].message;
  return new Response(JSON.stringify(response));} catch (e) {  return new Response(e);}
```

## OpenAI-Compatible Endpoint

You can also access DeepSeek models using the OpenAI API schema through the [REST API](https://developers.cloudflare.com/ai-gateway/usage/rest-api/). Send your requests to:

```
https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1/chat/completions
```

Specify:

```
{"model": "deepseek/{model}"}
```
