# Anthropic

> Configure Anthropic Claude models as the LLM provider in Mem0 with API key setup and usage examples.

To use Anthropic's models, please set the `ANTHROPIC_API_KEY` which you find on their [Account Settings Page](https://console.anthropic.com/account/keys).

## Usage

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

  os.environ["OPENAI_API_KEY"] = "your-api-key" # used for embedding model
  os.environ["ANTHROPIC_API_KEY"] = "your-api-key"

  config = {
      "llm": {
          "provider": "anthropic",
          "config": {
              "model": "claude-sonnet-4-6",
              "temperature": 0.1,
              "max_tokens": 2000,
          }
      }
  }

  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: 'anthropic',
      config: {

      },
    },

  const memory = new Memory(config);
  const messages = [
