MetaGPT: The Multi-Agent Framework

Assign different roles to GPTs to form a collaborative software entity for complex tasks.

1. MetaGPT takes a one line requirement as input and outputs user stories / competitive analysis / requirements / data structures / APIs / documents, etc.
2. Internally, MetaGPT includes product managers / architects / project managers / engineers. It provides the entire process of a software company along with carefully orchestrated SOPs.
   1. Code = SOP(Team) is the core philosophy. We materialize SOP and apply it to teams composed of LLMs.

MetaGPT's Abilities

Examples (fully generated by GPT-4)

For example, if you type python startup.py "Design a RecSys like Toutiao", you would get many outputs, one of them is data & api design

It costs approximately $0.2 (in GPT-4 API fees) to generate one example with analysis and design, and around $2.0 for a full project.

Installation

Installation Video Guide

• Matthew Berman: How To Install MetaGPT - Build A Startup With One Prompt!!

Traditional Installation

# Step 1: Ensure that NPM is installed on your system. Then install mermaid-js. (If you don't have npm in your computer, please go to the Node.js official website to install Node.js https://nodejs.org/ and then you will have npm tool in your computer.)
npm --version
sudo npm install -g @mermaid-js/mermaid-cli

# Step 2: Ensure that Python 3.9+ is installed on your system. You can check this by using:
python --version

# Step 3: Clone the repository to your local machine, and install it.
git clone https://github.com/geekan/metagpt
cd metagpt
pip install -e.

Note:

• If already have Chrome, Chromium, or MS Edge installed, you can skip downloading Chromium by setting the environment variable PUPPETEER_SKIP_CHROMIUM_DOWNLOAD to true.

• Some people are having issues installing this tool globally. Installing it locally is an alternative solution,

  npm install @mermaid-js/mermaid-cli

• don't forget to the configuration for mmdc in config.yml

  PUPPETEER_CONFIG: "./config/puppeteer-config.json"
  MMDC: "./node_modules/.bin/mmdc"

• if pip install -e. fails with error [Errno 13] Permission denied: '/usr/local/lib/python3.11/dist-packages/test-easy-install-13129.write-test', try instead running pip install -e. --user

• To convert Mermaid charts to SVG, PNG, and PDF formats. In addition to the Node.js version of Mermaid-CLI, you now have the option to use Python version Playwright, pyppeteer or mermaid.ink for this task.

  • Playwright

    • Install Playwright

    pip install playwright

    • Install the Required Browsers

    to support PDF conversion, please install Chrominum.

    playwright install --with-deps chromium

    • modify config.yaml

    uncomment MERMAID_ENGINE from config.yaml and change it to playwright

    MERMAID_ENGINE: playwright

  • pyppeteer

    • Install pyppeteer

    pip install pyppeteer

    • Use your own Browsers

    pyppeteer allows you use installed browsers, please set the following envirment

    export PUPPETEER_EXECUTABLE_PATH = /path/to/your/chromium or edge or chrome

    please do not use this command to install browser, it is too old

    pyppeteer-install

    • modify config.yaml

    uncomment MERMAID_ENGINE from config.yaml and change it to pyppeteer

    MERMAID_ENGINE: pyppeteer

  • mermaid.ink

    • modify config.yaml

    uncomment MERMAID_ENGINE from config.yaml and change it to ink

    MERMAID_ENGINE: ink

    Note: this method does not support pdf export.

Installation by Docker

# Step 1: Download metagpt official image and prepare config.yaml
docker pull metagpt/metagpt:latest
mkdir -p /opt/metagpt/{config,workspace}
docker run --rm metagpt/metagpt:latest cat /app/metagpt/config/config.yaml > /opt/metagpt/config/key.yaml
vim /opt/metagpt/config/key.yaml # Change the config

# Step 2: Run metagpt demo with container
docker run --rm \
    --privileged \
    -v /opt/metagpt/config/key.yaml:/app/metagpt/config/key.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest \
    python startup.py "Write a cli snake game"

# You can also start a container and execute commands in it
docker run --name metagpt -d \
    --privileged \
    -v /opt/metagpt/config/key.yaml:/app/metagpt/config/key.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest

docker exec -it metagpt /bin/bash
$ python startup.py "Write a cli snake game"

The command docker run ... do the following things:

• Run in privileged mode to have permission to run the browser
• Map host configure file /opt/metagpt/config/key.yaml to container /app/metagpt/config/key.yaml
• Map host directory /opt/metagpt/workspace to container /app/metagpt/workspace
• Execute the demo command python startup.py "Write a cli snake game"

Build image by yourself

# You can also build metagpt image by yourself.
git clone https://github.com/geekan/MetaGPT.git
cd MetaGPT && docker build -t metagpt:custom .

Configuration

• Configure your OPENAI_API_KEY in any of config/key.yaml / config/config.yaml / env
• Priority order: config/key.yaml > config/config.yaml > env

# Copy the configuration file and make the necessary modifications.
cp config/config.yaml config/key.yaml

Variable Name	config/key.yaml	env
OPENAI_API_KEY # Replace with your own key	OPENAI_API_KEY: "sk-..."	export OPENAI_API_KEY="sk-..."
OPENAI_API_BASE # Optional	OPENAI_API_BASE: "https://<YOUR_SITE>/v1"	export OPENAI_API_BASE="https://<YOUR_SITE>/v1"

Tutorial: Initiating a startup

# Run the script
python startup.py "Write a cli snake game"
# Do not hire an engineer to implement the project
python startup.py "Write a cli snake game" --implement False
# Hire an engineer and perform code reviews
python startup.py "Write a cli snake game" --code_review True

After running the script, you can find your new project in the workspace/ directory.

Preference of Platform or Tool

You can tell which platform or tool you want to use when stating your requirements.

python startup.py "Write a cli snake game based on pygame"
