MemGPT: Build Ultimate LLM Agents with Infinite Memory

MemGPT is an innovative open-source project that enables users to construct Large Language Model (LLM) agents equipped with long-term memory and customizable tools. This groundbreaking framework provides a method for LLM agents to manage extended memory and state, connect to external data sources such as PDF files, and define and invoke custom tools like performing Google searches.

Key Features

Long-Term Memory Management

MemGPT agents can retain and utilize information over extended periods, significantly enhancing their ability to maintain context in lengthy conversations or complex tasks.

External Data Source Integration

Agents can connect to and retrieve information from various external sources, expanding their knowledge base beyond their initial training data.

Custom Tool Definition and Execution

Users can create and implement specialized tools tailored to specific tasks or domains, greatly increasing the versatility of MemGPT agents.

Use Cases

Conversational Agents

MemGPT enables the creation of sophisticated chatbots capable of engaging in nuanced, context-aware dialogues across multiple sessions.

Information Retrieval

By leveraging connections to external data sources, MemGPT agents can efficiently locate and reference specific information, making them valuable for research and data analysis tasks.

Customized Functionality

Users can define domain-specific functions for their agents, such as specialized search capabilities or data analysis tools, adapting them to particular industries or applications.

Research and Development

Developers and researchers can utilize MemGPT as a platform for conducting LLM-related experiments and pushing the boundaries of AI capabilities.

Getting Started with MemGPT

Installation and Setup

To begin using MemGPT, follow these steps:

1. Install the package using pip:

   pip install pymemgpt

2. If you plan to use OpenAI’s services, set your API key as an environment variable:

   export OPENAI_API_KEY=your_openai_api_key_here

3. For a quick start with OpenAI’s backend:

   memgpt quickstart --backend openai

Alternatively, to use MemGPT’s free hosted endpoint:

   memgpt quickstart --backend memgpt

For advanced configuration options or to use different LLM backends, including local LLMs, run:

memgpt configure

Using the Command Line Interface (CLI)

To create and interact with a MemGPT agent via the CLI, use the following command:

memgpt run

This command supports several optional flags:

• --agent: Specify the name of the agent to create or continue a conversation with.
• --first: Allow the user to send the first message.
• --debug: Display debug logs for troubleshooting.
• --no-verify: Bypass message verification.
• --yes or -y: Skip confirmation prompts and use default values.

For a comprehensive list of CLI options, refer to the CLI documentation.

Deploying MemGPT as a Service

MemGPT can also be deployed as a service, requiring authentication with an admin password. Set this password using:

export MEMGPT_SERVER_PASS=your_chosen_password

There are two methods to launch the MemGPT service:

Option 1: Using Docker Compose (Recommended)

1. Install Docker on your system.
2. Clone the MemGPT repository:

   git clone git@github.com:cpacker/MemGPT.git

3. Run docker compose up.
4. Access the developer portal at memgpt.localhost in your web browser.

Option 2: Using the CLI

1. Run memgpt server.
2. Access the developer portal at localhost:8283 in your web browser.

Once the server is running, you can connect to it (at memgpt.localhost for Docker Compose or localhost:8283 for CLI) using the Python client or REST API to create users, agents, and perform other operations.
