# DeepSeek

> Configure DeepSeek as an LLM provider in Mem0 with API key setup and optional custom endpoint configuration.

To use DeepSeek LLM models, you have to set the `DEEPSEEK_API_KEY` environment variable. You can also optionally set `DEEPSEEK_API_BASE` if you need to use a different API endpoint (defaults to "[https://api.deepseek.com](https://api.deepseek.com)").

## Usage

<CodeGroup>
  ```python Python theme={null}
  import os
  from mem0 import Memory

  os.environ["DEEPSEEK_API_KEY"] = "your-api-key"
  os.environ["OPENAI_API_KEY"] = "your-api-key" # for embedder model

  config = {
      "llm": {
          "provider": "deepseek",
          "config": {
              "model": "deepseek-chat",  # default model
              "temperature": 0.2,
              "max_tokens": 2000,
              "top_p": 1.0
          }
      }
  }

  m = Memory.from_config(config)
  messages = [
      {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
      {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
      {"role": "user", "content": "I’m not a big fan of thriller movies but I love sci-fi movies."},
      {"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
  ]
  m.add(messages, user_id="alice", metadata={"category": "movies"})
  ```

  ```typescript TypeScript theme={null}
  import { Memory } from 'mem0ai/oss';

  const config = {
    llm: {
      provider: 'deepseek',
      config: {
        apiKey: process.env.DEEPSEEK_API_KEY || '',
        model: 'deepseek-chat',
        temperature: 0.2,
        maxTokens: 2000,
        top_p: 1.0,
      },
    },
  };
  const memory = new Memory(config);
  const messages = [
      {"role": "user", "content": "I'm planning to watch a movie tonight. Any recommendations?"},
      {"role": "assistant", "content": "How about thriller movies? They can be quite engaging."},
      {"role": "user", "content": "I’m not a big fan of thriller movies but I love sci-fi movies."},
      {"role": "assistant", "content": "Got it! I'll avoid thriller recommendations and suggest sci-fi movies in the future."}
  ];
  await memory.add(messages, { userId: 'alice', metadata: { category: 'movies' } });
  ```
</CodeGroup>

You can also configure the API base URL in the config:

```python theme={null}
config = {
    "llm": {
        "provider": "deepseek",
        "config": {
            "model": "deepseek-chat",
            "deepseek_base_url": "https://your-custom-endpoint.com",
            "api_key": "your-api-key"  # alternatively to using environment variable
        }
    }
}
```

## Config

All available parameters for the `deepseek` config are present in [Master List of All Params in Config](../config).
