Overview#

In this tutorial, we will explore the BaseMessage class. The topics covered include:

  1. Introduction to the BaseMessage class.

  2. Creating a BaseMessage instance.

  3. Understanding the properties of the BaseMessage class.

  4. Using the methods of the BaseMessage class.

  5. Give message to ChatAgent

Introduction#

The BaseMessage class is the base class for message objects used in the CAMEL chat system. It is designed to provide a consistent structure for the messages in the system and allow for easy conversion between different message types.

Installation#

Ensure you have CAMEL AI installed in your Python environment:

[ ]:
%pip install "camel-ai==0.2.1"

Setting Up API Keys#

You’ll need to set up your API keys for OpenAI.

[ ]:
import os
from getpass import getpass

# Prompt for the API key securely
openai_api_key = getpass('Enter your API key: ')
os.environ["OPENAI_API_KEY"] = openai_api_key
Enter your API key: ··········

Creating a BaseMessage Instance#

To create a BaseMessage instance, you need to provide the following arguments:

  • role_name: The name of the user or assistant role.

  • role_type: The type of role, either RoleType.ASSISTANT or RoleType.USER.

  • meta_dict: An optional metadata dictionary for the message.

  • content: The content of the message.

Here’s an example of creating a BaseMessage instance:

[ ]:
from camel.messages import BaseMessage
from camel.types import RoleType

message = BaseMessage(
    role_name="test_user",
    role_type=RoleType.USER,
    content="test content",
    meta_dict={}
)

Additionally, the BaseMessage class provides class methods to easily create user and assistant agent messages:

  1. Creating a user agent message:

[ ]:
from camel.messages import BaseMessage

user_message = BaseMessage.make_user_message(
    role_name="user_name",
    content="test content for user",
)
  1. Creating an assistant agent message:

[ ]:
from camel.messages import BaseMessage

assistant_message = BaseMessage.make_assistant_message(
    role_name="assistant_name",
    content="test content for assistant",
)

Using the Methods of the BaseMessage Class#

The BaseMessage class offers several methods:

  1. Creating a new instance with updated content:

[ ]:
new_message = message.create_new_instance("new test content")
print(isinstance(new_message, BaseMessage))
True
  1. Converting to an OpenAIMessage object:

[ ]:
from camel.types import OpenAIBackendRole
openai_message = message.to_openai_message(role_at_backend=OpenAIBackendRole.USER)
print(openai_message == {"role": "user", "content": "test content"})
True
  1. Converting to an OpenAISystemMessage object:

[ ]:
openai_system_message = message.to_openai_system_message()
print(openai_system_message == {"role": "system", "content": "test content"})
True
  1. Converting to an OpenAIUserMessage object:

[ ]:
openai_user_message = message.to_openai_user_message()
print(openai_user_message == {"role": "user", "content": "test content"})
True
  1. Converting to an OpenAIAssistantMessage object:

[ ]:
openai_assistant_message = message.to_openai_assistant_message()
print(openai_assistant_message == {"role": "assistant", "content": "test content"})
True
  1. Converting to a dictionary:

[ ]:
message_dict = message.to_dict()
print(message_dict == {
    "role_name": "test_user",
    "role_type": "USER",
    "content": "test content"
})
True

These methods allow you to convert a BaseMessage instance into different message types depending on your needs.

Give message to ChatAgent#

[ ]:
from camel.agents import ChatAgent
from camel.messages import BaseMessage

# Define system message
sys_msg = BaseMessage.make_assistant_message(
    role_name="Assistant",
    content="You are a helpful assistant.",
)

# Set agent
camel_agent = ChatAgent(system_message=sys_msg)

# Set user message
user_msg = BaseMessage.make_user_message(
    role_name="User",
    content="""Say hi to CAMEL AI, one open-source community dedicated to the
    study of autonomous and communicative agents.""",
)

# Get response information
response = camel_agent.step(user_msg)
print(response.msgs[0].content)
Hello, CAMEL AI! It's great to connect with a community dedicated to the study of autonomous and communicative agents. Your work in this fascinating field is sure to lead to exciting advancements and innovations. If there's anything specific you'd like to discuss or explore, feel free to share!

In this session, we introduced the BaseMessage class and its conversion to different types of messages. These components play essential roles in the CAMEL chat system, facilitating the creation, management, and interpretation of messages with clarity.
