Mem0 AI SDK Provider

The Mem0 AI SDK Provider is a community-maintained library developed by Mem0 to integrate with the Vercel AI SDK. This library brings enhanced AI interaction capabilities to your applications by introducing persistent memory functionality. With Mem0, language model conversations gain memory, enabling more contextualized and personalized responses based on past interactions.

• 🚀 Support for multiple LLM providers
• 📝 Rich message format support
• ⚡ Streaming capabilities
• 🔍 Context-aware responses

Installation

npm install @mem0/vercel-ai-provider

Before We Begin

Setting Up Mem0

1. Obtain your Mem0 API Key from the Mem0 dashboard.

2. Initialize the Mem0 Client:

import { createMem0 } from "@mem0/vercel-ai-provider";

const mem0 = createMem0({
  provider: "openai",
  mem0ApiKey: "m0-xxx",
  apiKey: "openai-api-key",
  config: {
    compatibility: "strict",
    // Additional model-specific configuration options can be added here.
  },
});

Note

By default, the openai provider is used, so specifying it is optional:

const mem0 = createMem0();

For better security, consider setting MEM0_API_KEY and OPENAI_API_KEY as environment variables.

3. Add Memories to Enhance Context:

import { LanguageModelV1Prompt } from "ai";
import { addMemories } from "@mem0/vercel-ai-provider";

const messages: LanguageModelV1Prompt = [
  {
    role: "user",
    content: [
      { type: "text", text: "I love red cars." },
      { type: "text", text: "I like Toyota Cars." },
      { type: "text", text: "I prefer SUVs." },
    ],
  },
];

await addMemories(messages, { user_id: "borat" });

These memories are now stored in your profile. You can view and manage them on the Mem0 Dashboard.

Note:

For standalone features, such as addMemories and retrieveMemories, you must either set MEM0_API_KEY as an environment variable or pass it directly in the function call.

Example:

await addMemories(messages, { user_id: "borat", mem0ApiKey: "m0-xxx", org_id: "org_xx", project_id: "proj_xx" });
await retrieveMemories(prompt, { user_id: "borat", mem0ApiKey: "m0-xxx", org_id: "org_xx", project_id: "proj_xx" });
await getMemories(prompt, { user_id: "borat", mem0ApiKey: "m0-xxx", org_id: "org_xx", project_id: "proj_xx" });

Note:

retrieveMemories enriches the prompt with relevant memories from your profile, while getMemories returns the memories in array format which can be used for further processing.

Usage Examples

1. Basic Text Generation with Memory Context

import { generateText } from "ai";
import { createMem0 } from "@mem0/vercel-ai-provider";

const mem0 = createMem0();

const { text } = await generateText({
  model: mem0("gpt-4-turbo", {
    user_id: "borat",
  }),
  prompt: "Suggest me a good car to buy!",
});

2. Combining OpenAI Provider with Memory Utils

import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
import { retrieveMemories } from "@mem0/vercel-ai-provider";

const prompt = "Suggest me a good car to buy.";
const memories = await retrieveMemories(prompt, { user_id: "borat" });

const { text } = await generateText({
  model: openai("gpt-4-turbo"),
  prompt: prompt,
  system: memories,
});

3. Structured Message Format with Memory

import { generateText } from "ai";
import { createMem0 } from "@mem0/vercel-ai-provider";

const mem0 = createMem0();

const { text } = await generateText({
  model: mem0("gpt-4-turbo", {
    user_id: "borat",
  }),
  messages: [
    {
      role: "user",
      content: [
        { type: "text", text: "Suggest me a good car to buy." },
        { type: "text", text: "Why is it better than the other cars for me?" },
        { type: "text", text: "Give options for every price range." },
      ],
    },
  ],
});

4. Advanced Memory Integration with OpenAI

import { generateText, LanguageModelV1Prompt } from "ai";
import { openai } from "@ai-sdk/openai";
import { retrieveMemories } from "@mem0/vercel-ai-provider";

// New format using system parameter for memory context
const messages: LanguageModelV1Prompt = [
  {
    role: "user",
    content: [
      { type: "text", text: "Suggest me a good car to buy." },
      { type: "text", text: "Why is it better than the other cars for me?" },
      { type: "text", text: "Give options for every price range." },
    ],
  },
];

const memories = await retrieveMemories(messages, { user_id: "borat" });

const { text } = await generateText({
  model: openai("gpt-4-turbo"),
  messages: messages,
  system: memories,
});

5. Streaming Responses with Memory Context

import { streamText } from "ai";
import { createMem0 } from "@mem0/vercel-ai-provider";

const mem0 = createMem0();

const { textStream } = await streamText({
  model: mem0("gpt-4-turbo", {
    user_id: "borat",
  }),
  prompt:
    "Suggest me a good car to buy! Why is it better than the other cars for me? Give options for every price range.",
});

for await (const textPart of textStream) {
  process.stdout.write(textPart);
}

Core Functions

• createMem0(): Initializes a new mem0 provider instance with optional configuration
• retrieveMemories(): Enriches prompts with relevant memories
• addMemories(): Add memories to your profile
• getMemories(): Get memories from your profile in array format

Configuration Options

const mem0 = createMem0({
  config: {
    ...
    // Additional model-specific configuration options can be added here.
  },
});

Best Practices

1. User Identification: Always provide a unique user_id identifier for consistent memory retrieval
2. Context Management: Use appropriate context window sizes to balance performance and memory
3. Error Handling: Implement proper error handling for memory operations
4. Memory Cleanup: Regularly clean up unused memory contexts to optimize performance

We also have support for agent_id, app_id, and run_id. Refer Docs.

Notes

• Requires proper API key configuration for underlying providers (e.g., OpenAI)
• Memory features depend on proper user identification via user_id
• Supports both streaming and non-streaming responses
• Compatible with all Vercel AI SDK features and patterns
