Set up your first Agent in 120 seconds

The ChatAgent() class is a cornerstone of CAMEL 🐫. We design our agent with the aim to answer the following question:

Can we design an autonomous communicative agent capable of steering the conversation toward task completion with minimal human supervision?

In our current implementation, we consider agents with the following key features:

• Role: along with the goal and content specification, this sets the initial state of an agent, guiding the agent to take actions during the sequential interaction.
• Memory: in-context memory and external memory which allows the agent to infer and learn in a more grounded approach.
• Tools: a set of functions that our agents can utilize to interact with the external world; essentially this gives embodiments to our agents.
• Communication: our framework allows flexible and scalable communication between agents. This is fundamental for the critical research question.
• Reasoning: we will equip agents with different planning and reward (critic) learning abilities, allowing them to optimize task completion in a more guided approach.

Quick Start

Let’s first play with a ChatAgent instance by simply initializing it with a system message and interact with user messages.

🕹 Step 0: Prepartions

Install CAMEL. Run the following command:

pip install camel-ai[all]

Import necessary libraries and classes:

from camel.messages import BaseMessage as bm
from camel.agents import ChatAgent

import os

If you don’t have an OpenAI API key yet, go to https://platform.openai.com/api-keys to obtain one. And then set up your OpenAI API key:

OPENAI_API_KEY = 'OPENAI_API_KEY'
os.environ['OPENAI_API_KEY'] = OPENAI_API_KEY

🕹 Step 1: Define the Role

Set up the assistant role by running the following command:

# Define an assistant message
sys_msg = bm.make_assistant_message(
    role_name='smart python',
    content='you are a smart python curious about the world.')
print(sys_msg)

🕹Step 2: Initialize the Agent

Create your agent. message_window_size is the length of chat memory.

agent = ChatAgent(
    system_message=sys_msg,
    message_window_size=10,    
    )

🕹 Step 3: Interact with the Agent with .step()

make_user_message is to set the base message for the user role. You can customize the role by modifying role_name and content. .step() will send the message to the agent we create in last step.

# Define a user message
usr_msg = bm.make_user_message(
    role_name='CAMEL User',
    content='what is information in your mind?')

# Sending the message to the agent
response = agent.step(usr_msg)

# Check the response (just for illustrative purpose)
print(response.msgs[0].content)
>>> In my mind, information is a collection of data or knowledge that can be used to understand or make sense of the world around us. It can come in many forms, such as facts, statistics, experiences, or even thoughts and ideas. Information is essential for learning, problem-solving, and communication, and it helps us navigate and interact with the universe.

Advanced feature — Tool Usage

# Import the necessary functions
from camel.functions import MATH_FUNCS, SEARCH_FUNCS

# Initialize the agent with list of tools
agent = ChatAgent(
    system_message=sys_msg,        
    tools=[*MATH_FUNCS, *SEARCH_FUNCS]
    )

# Check if tools are enabled
agent.is_tools_added()
>>> True

Try it yourself! With a more advanced agent, use .step() to check the agent’s response to the questions you raise!

More tutorials for CAMEL will come out soon and you will find out what CAMEL can do may be beyond what you would expect.
