CAMEL: Communicative Agents for “Mind” Exploration of Large Language Model Society

Overview

The rapid advancement of conversational and chat-based language models has led to remarkable progress in complex task-solving. However, their success heavily relies on human input to guide the conversation, which can be challenging and time-consuming. This paper explores the potential of building scalable techniques to facilitate autonomous cooperation among communicative agents and provide insight into their "cognitive" processes. To address the challenges of achieving autonomous cooperation, we propose a novel communicative agent framework named role-playing. Our approach involves using inception prompting to guide chat agents toward task completion while maintaining consistency with human intentions. We showcase how role-playing can be used to generate conversational data for studying the behaviors and capabilities of chat agents, providing a valuable resource for investigating conversational language models. Our contributions include introducing a novel communicative agent framework, offering a scalable approach for studying the cooperative behaviors and capabilities of multi-agent systems, and open-sourcing our library to support research on communicative agents and beyond. The GitHub repository of this project is made publicly available on: https://github.com/camel-ai/camel.

Community

🐫 CAMEL is an open-source library designed for the study of autonomous and communicative agents. We believe that studying these agents on a large scale offers valuable insights into their behaviors, capabilities, and potential risks. To facilitate research in this field, we implement and support various types of agents, tasks, prompts, models, and simulated environments.

We provide a demo showcasing a conversation between two ChatGPT agents playing roles as a python programmer and a stock trader collaborating on developing a trading bot for stock market.

Installation

From PyPI

To install the base CAMEL library:

pip install camel-ai

Some features require extra dependencies:

• To install with all dependencies:

  pip install 'camel-ai[all]'
  

• To use the HuggingFace agents:

  pip install 'camel-ai[huggingface-agent]'
  

• To enable RAG or use agent memory:

  pip install 'camel-ai[tools]'
  

From Source

Install CAMEL from source with poetry (Recommended):

# Make sure your python version is later than 3.10
# You can use pyenv to manage multiple python verisons in your sytstem

# Clone github repo
git clone https://github.com/camel-ai/camel.git

# Change directory into project directory
cd camel

# If you didn't install peotry before
pip install poetry  # (Optional)

# We suggest using python 3.10
poetry env use python3.10  # (Optional)

# Activate CAMEL virtual environment
poetry shell

# Install the base CAMEL library
# It takes about 90 seconds
poetry install

# Install CAMEL with all dependencies
poetry install -E all # (Optional)

# Exit the virtual environment
exit

[!TIP] If you encounter errors when running poetry install, it may be due to a cache-related problem. You can try running:

poetry install --no-cache

Install CAMEL from source with conda and pip:

# Create a conda virtual environment
conda create --name camel python=3.10

# Activate CAMEL conda environment
conda activate camel

# Clone github repo
git clone -b v0.2.2 https://github.com/camel-ai/camel.git

# Change directory into project directory
cd camel

# Install CAMEL from source
pip install -e .

# Or if you want to use all other extra packages
pip install -e .[all] # (Optional)

From Docker

Example

You can find a list of tasks for different sets of assistant and user role pairs here.

As an example, to run the role_playing.py script:

First, you need to add your OpenAI API key to system environment variables. The method to do this depends on your operating system and the shell you're using.

For Bash shell (Linux, macOS, Git Bash on Windows):

# Export your OpenAI API key
export OPENAI_API_KEY=<insert your OpenAI API key>
OPENAI_API_BASE_URL=<inert your OpenAI API BASE URL>  #(Should you utilize an OpenAI proxy service, kindly specify this)

For Windows Command Prompt:

REM export your OpenAI API key
set OPENAI_API_KEY=<insert your OpenAI API key>
set OPENAI_API_BASE_URL=<inert your OpenAI API BASE URL>  #(Should you utilize an OpenAI proxy service, kindly specify this)

For Windows PowerShell:

# Export your OpenAI API key
$env:OPENAI_API_KEY="<insert your OpenAI API key>"
$env:OPENAI_API_BASE_URL="<inert your OpenAI API BASE URL>"  #(Should you utilize an OpenAI proxy service, kindly specify this)

Replace <insert your OpenAI API key> with your actual OpenAI API key in each case. Make sure there are no spaces around the = sign.

After setting the OpenAI API key, you can run the script:

# You can change the role pair and initial prompt in role_playing.py
python examples/ai_society/role_playing.py

Please note that the environment variable is session-specific. If you open a new terminal window or tab, you will need to set the API key again in that new session.

Use Open-Source Models as Backends (ex. using Ollama to set Llama 3 locally)

• Download Ollama.
• After setting up Ollama, pull the Llama3 model by typing the following command into the terminal:

  ollama pull llama3
  

• Create a ModelFile similar the one below in your project directory.

  FROM llama3
  
  # Set parameters
  PARAMETER temperature 0.8
  PARAMETER stop Result
  
  # Sets a custom system message to specify the behavior of the chat assistant
  
  # Leaving it blank for now.
  
  SYSTEM """ """
  

• Create a script to get the base model (llama3) and create a custom model using the ModelFile above. Save this as a .sh file:

  #!/bin/zsh
  
  # variables
  model_name="llama3"
  custom_model_name="camel-llama3"
  
  #get the base model
  ollama pull $model_name
  
  #create the model file
  ollama create $custom_model_name -f ./Llama3ModelFile
  

• Navigate to the directory where the script and ModelFile are located and run the script. Enjoy your Llama3 model, enhanced by CAMEL's excellent agents.

  from camel.agents import ChatAgent
  from camel.messages import BaseMessage
  from camel.models import ModelFactory
  from camel.types import ModelPlatformType
  
  ollama_model = ModelFactory.create(
      model_platform=ModelPlatformType.OLLAMA,
      model_type="llama3",
      url="http://localhost:11434/v1",
      model_config_dict={"temperature": 0.4},
  )
  
  assistant_sys_msg = BaseMessage.make_assistant_message(
      role_name="Assistant",
      content="You are a helpful assistant.",
  )
  agent = ChatAgent(assistant_sys_msg, model=ollama_model, token_limit=4096)
  
  user_msg = BaseMessage.make_user_message(
      role_name="User", content="Say hi to CAMEL"
  )
  assistant_response = agent.step(user_msg)
  print(assistant_response.msg.content)
  

Use Open-Source Models as Backends (ex. using vLLM to set Phi-3 locally)

• Install vLLM
• After setting up vLLM, start an OpenAI compatible server for example by

  python -m vllm.entrypoints.openai.api_server --model microsoft/Phi-3-mini-4k-instruct --api-key vllm --dtype bfloat16
  

• Create and run following script (more details please refer to this example)

  from camel.agents import ChatAgent
  from camel.messages import BaseMessage
  from camel.models import ModelFactory
  from camel.types import ModelPlatformType
  
  vllm_model = ModelFactory.create(
      model_platform=ModelPlatformType.VLLM,
      model_type="microsoft/Phi-3-mini-4k-instruct",
      url="http://localhost:8000/v1",
      model_config_dict={"temperature": 0.0},
      api_key="vllm",
  )
  
  assistant_sys_msg = BaseMessage.make_assistant_message(
      role_name="Assistant",
      content="You are a helpful assistant.",
  )
  agent = ChatAgent(assistant_sys_msg, model=vllm_model, token_limit=4096)
  
  user_msg = BaseMessage.make_user_message(
      role_name="User",
      content="Say hi to CAMEL AI",
  )
  assistant_response = agent.step(user_msg)
  print(assistant_response.msg.content)
