<Snippet file="security-compliance.mdx" />

Integrate Mem0’s memory capabilities with OpenAI’s Inbuilt Tools to create AI agents with persistent memory.

## Getting Started

### Installation

```bash
npm install mem0ai openai zod
```

## Environment Setup

Save your Mem0 and OpenAI API keys in a `.env` file:

```
MEM0_API_KEY=your_mem0_api_key
OPENAI_API_KEY=your_openai_api_key
```

Get your Mem0 API key from the [Mem0 Dashboard](https://app.mem0.ai/dashboard/api-keys).

### Configuration

```javascript
const mem0Config = {
    apiKey: process.env.MEM0_API_KEY,
    user_id: "sample-user",
};

const openAIClient = new OpenAI();
const mem0Client = new MemoryClient(mem0Config);
```

### Adding Memories

Store user preferences, past interactions, or any relevant information:
<CodeGroup>
```javascript JavaScript
async function addUserPreferences() {
    const mem0Client = new MemoryClient(mem0Config);
    
    const userPreferences = "I Love BMW, Audi and Porsche. I Hate Mercedes. I love Red cars and Maroon cars. I have a budget of 120K to 150K USD. I like Audi the most.";
    
    await mem0Client.add([{
        role: "user",
        content: userPreferences,
    }], mem0Config);
}

await addUserPreferences();
```

```json Output (Memories)
 [
  {
    "id": "ff9f3367-9e83-415d-b9c5-dc8befd9a4b4",
    "data": { "memory": "Loves BMW, Audi, and Porsche" },
    "event": "ADD"
  },
  {
    "id": "04172ce6-3d7b-45a3-b4a1-ee9798593cb4",
    "data": { "memory": "Hates Mercedes" },
    "event": "ADD"
  },
  {
    "id": "db363a5d-d258-4953-9e4c-777c120de34d",
    "data": { "memory": "Loves red cars and maroon cars" },
    "event": "ADD"
  },
  {
    "id": "5519aaad-a2ac-4c0d-81d7-0d55c6ecdba8",
    "data": { "memory": "Has a budget of 120K to 150K USD" },
    "event": "ADD"
  },
  {
    "id": "523b7693-7344-4563-922f-5db08edc8634",
    "data": { "memory": "Likes Audi the most" },
    "event": "ADD"
  }
]
```
</CodeGroup>
### Retrieving Memories

Search for relevant memories based on the current user input:

```javascript
const relevantMemories = await mem0Client.search(userInput, mem0Config);
```

### Structured Responses with Zod

Define structured response schemas to get consistent output formats:

```javascript
// Define the schema for a car recommendation
const CarSchema = z.object({
  car_name: z.string(),
  car_price: z.string(),
  car_url: z.string(),
  car_image: z.string(),
  car_description: z.string(),
});

// Schema for a list of car recommendations
const Cars = z.object({
  cars: z.array(CarSchema),
});

// Create a function tool based on the schema
const carRecommendationTool = zodResponsesFunction({ 
    name: "carRecommendations", 
    parameters: Cars 
});

// Use the tool in your OpenAI request
const response = await openAIClient.responses.create({
    model: "gpt-4o",
    tools: [{ type: "web_search_preview" }, carRecommendationTool],
    input: `${getMemoryString(relevantMemories)}\n${userInput}`,
});
```

### Using Web Search

Combine memory with web search for up-to-date recommendations:

```javascript
const response = await openAIClient.responses.create({
    model: "gpt-4o",
    tools: [{ type: "web_search_preview" }, carRecommendationTool],
    input: `${getMemoryString(relevantMemories)}\n${userInput}`,
});
```

## Examples

### Complete Car Recommendation System

```javascript
import MemoryClient from "mem0ai";
import { OpenAI } from "openai";
import { zodResponsesFunction } from "openai/helpers/zod";
import { z } from "zod";
import dotenv from 'dotenv';

dotenv.config();

const mem0Config = {
    apiKey: process.env.MEM0_API_KEY,
    user_id: "sample-user",
};

async function run() {
    // Responses without memories
    console.log("\n\nRESPONSES WITHOUT MEMORIES\n\n");
    await main();

    // Adding sample memories
    await addSampleMemories();

    // Responses with memories
    console.log("\n\nRESPONSES WITH MEMORIES\n\n");
    await main(true);
}

// OpenAI Response Schema
const CarSchema = z.object({
  car_name: z.string(),
  car_price: z.string(),
  car_url: z.string(),
  car_image: z.string(),
  car_description: z.string(),
});

const Cars = z.object({
  cars: z.array(CarSchema),
});

async function main(memory = false) {
  const openAIClient = new OpenAI();
  const mem0Client = new MemoryClient(mem0Config);

  const input = "Suggest me some cars that I can buy today.";

  const tool = zodResponsesFunction({ name: "carRecommendations", parameters: Cars });

  // Store the user input as a memory
  await mem0Client.add([{
    role: "user",
    content: input,
  }], mem0Config);

  // Search for relevant memories
  let relevantMemories = []
  if (memory) {
    relevantMemories = await mem0Client.search(input, mem0Config);
  }

  const response = await openAIClient.responses.create({
    model: "gpt-4o",
    tools: [{ type: "web_search_preview" }, tool],
    input: `${getMemoryString(relevantMemories)}\n${input}`,
  });

  console.log(response.output);
}

async function addSampleMemories() {
  const mem0Client = new MemoryClient(mem0Config);

  const myInterests = "I Love BMW, Audi and Porsche. I Hate Mercedes. I love Red cars and Maroon cars. I have a budget of 120K to 150K USD. I like Audi the most.";
  
  await mem0Client.add([{
    role: "user",
    content: myInterests,
  }], mem0Config);
}

const getMemoryString = (memories) => {
    const MEMORY_STRING_PREFIX = "These are the memories I have stored. Give more weightage to the question by users and try to answer that first. You have to modify your answer based on the memories I have provided. If the memories are irrelevant you can ignore them. Also don't reply to this section of the prompt, or the memories, they are only for your reference. The MEMORIES of the USER are: \n\n";
    const memoryString = memories.map((mem) => `${mem.memory}`).join("\n") ?? "";
    return memoryString.length > 0 ? `${MEMORY_STRING_PREFIX}${memoryString}` : "";
};

run().catch(console.error);
```
