# OpenAI

> Configure OpenAI as an embedding provider in Mem0 using models like text-embedding-3-large for vector generation.

To use OpenAI embedding models, set the `OPENAI_API_KEY` environment variable. You can obtain the OpenAI API key from the [OpenAI Platform](https://platform.openai.com/account/api-keys).

### Usage

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

  os.environ["OPENAI_API_KEY"] = "your_api_key"

  config = {
      "embedder": {
          "provider": "openai",
          "config": {
              "model": "text-embedding-3-large"
          }
      }
  }

  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="john")
  ```

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

  const config = {
    embedder: {
      provider: 'openai',
      config: {
        apiKey: 'your-openai-api-key',
        model: 'text-embedding-3-large',
      },
    },
  };

  const memory = new Memory(config);
  await memory.add("I'm visiting Paris", { userId: "john" });
  ```
