Multi-Agent Dialog Framework

AutoGen provides a unified multi-agent dialog framework as a high-level abstraction of utilizing basis fashions. Think about you’ve got a gaggle of digital assistants who can discuss to one another and work collectively to finish complicated duties, like organizing an enormous occasion or managing a sophisticated venture. AutoGen helps them do that effectively and successfully.

Brokers

AutoGen brokers are part of the AutoGen framework. These brokers are designed to unravel duties via inter-agent conversations. Listed here are some notable options of AutoGen brokers:

• Conversable: Brokers in AutoGen are conversable, which implies Identical to folks discuss to one another, these digital helpers can ship and obtain messages to have discussions. This helps them work collectively.
• Customizable: Brokers in AutoGen could be personalized to combine LLMs, people, instruments, or a mix of them.

Construct-in Brokers in Autogen

We’ve created a particular class referred to as Conversable Agent that helps laptop applications discuss to one another to work on duties collectively. These brokers can ship messages and carry out totally different actions primarily based on the messages they get.

There are two predominant forms of brokers:

• Assistant Agent: This agent is sort of a useful AI assistant. It might write Python code so that you can run if you give it a activity. It makes use of a sensible program referred to as LLM (like GPT-4) to write down the code. It might additionally examine the outcomes and recommend fixes. You’ll be able to change the way it behaves by giving it new directions. You too can tweak how LLM works with it utilizing the llm_config.
• Person-Proxy Agent: This agent acts like a go-between for folks. It might ask people for assist or execute code when wanted. It might even use LLM to generate responses when it’s not executing code. You’ll be able to management code execution and LLM utilization with settings like code_execution_config and llm_config.

These brokers can discuss to one another with out human assist, however people can step in if wanted. You too can add extra options to them utilizing the register_reply() methodology.

Use Case: AutoGen’s Multi-agent Framework for Answering Person

Within the code snippet beneath, we outline an AssistantAgent referred to as “Agent1” to operate as an assistant to assist with common questions, “Agent2” to operate as an assistant to assist with technical a UserProxyAgent named “user_proxy” to behave as a mediator for the human consumer. We are going to use these brokers later to perform a selected activity.

import autogen
# Import the openai api key
config_list = config_list_from_json(env_or_file="OAI_CONFIG_LIST")

# Create two brokers
agent1 = autogen.AssistantAgent(
    identify="Agent 1",
    llm_config={
        "seed": 42,
        "config_list": config_list,
        "temperature": 0.7,
        "request_timeout": 1200,
    },
    system_message="Agent 1. I may also help with common questions.",
)

agent2 = autogen.AssistantAgent(
    identify="Agent 2",
    llm_config={
        "seed": 42,
        "config_list": config_list,
        "temperature": 0.7,
        "request_timeout": 1200,
    },
    system_message="Agent 2. I am right here to help with technical questions.",
)

# Create a Person Proxy agent
user_proxy = autogen.UserProxyAgent(
    identify="Person Proxy",
    human_input_mode="ALWAYS",
    code_execution_config=False,
)

# Create a chat group for the dialog
chat_group = autogen.GroupChat(
    brokers=[agent1, agent2, user_proxy],
    messages=[],
    max_round=10,
)

# Create a gaggle chat supervisor
chat_manager = autogen.GroupChatManager(groupchat=chat_group, llm_config=agent_config)

# Provoke the dialog with a consumer query
user_proxy.initiate_chat(
    chat_manager,
    message="Are you able to clarify the idea of machine studying?"
)

On this easy instance, two brokers, “Agent 1” and “Agent 2,” work collectively to supply solutions to a consumer’s questions. The “Person Proxy” agent facilitates communication between the consumer and the opposite brokers. This demonstrates a fundamental use case of AutoGen’s multi-agent dialog framework for answering consumer queries.

Supporting Numerous Dialog Patterns

AutoGen helps a wide range of dialog types, accommodating each absolutely automated and human-involved interactions.

Numerous Dialog Types

1. Autonomous Conversations: After an preliminary setup, you possibly can have absolutely automated conversations the place the brokers work independently.
2. Human-In-The-Loop: AutoGen could be configured to contain people within the dialog course of. For instance, you possibly can set the human_input_mode to “ALWAYS” to make sure human enter is included when wanted, which is efficacious in lots of functions.

Static vs Dynamic Conversations

AutoGen permits for each static and dynamic dialog patterns.

1. Static Conversations: These comply with predefined dialog buildings and are constant whatever the enter.
2. Dynamic Conversations: Dynamic conversations adapt to the precise circulate of the dialog, making them appropriate for complicated functions the place interplay patterns can’t be predetermined.

Approaches for Dynamic Conversations

AutoGen provides two strategies for reaching dynamic conversations:

Registered Auto-Reply

You’ll be able to arrange auto-reply features, permitting brokers to determine who ought to converse subsequent primarily based on the present message and context. This method is demonstrated in a gaggle chat instance, the place LLM determines the following speaker within the chat.

let’s discover a brand new use case for “Registered Auto-Reply” within the context of a dynamic group chat state of affairs the place an LLM (Language Mannequin) decides who the following speaker must be primarily based on the content material and context of the dialog.

Use Case: Collaborative Content material Creation

On this use case, we have now a dynamic group chat involving three brokers: a UserProxyAgent representing a consumer, a Author Agent, and an Editor Agent. The purpose is to collaboratively create written content material. The Registered Auto-Reply operate permits the LLM to determine when to change roles between writers and editors primarily based on the content material’s high quality and completion.

# Import the openai api key
config_list = config_list_from_json(env_or_file="OAI_CONFIG_LIST")

# Create brokers with LLM configurations
llm_config = {"config_list": config_list, "seed": 42}
user_proxy = autogen.UserProxyAgent(
    identify="User_proxy",
    system_message="A content material creator.",
    code_execution_config={"last_n_messages": 2, "work_dir": "content_creation"},
    human_input_mode="TERMINATE"
)

Assemble Brokers

author = autogen.AssistantAgent(
    identify="Author",
    llm_config=llm_config,
)

editor = autogen.AssistantAgent(
    identify="Editor",
    system_message="An editor for written content material.",
    llm_config=llm_config,
)

groupchat = autogen.GroupChat(brokers=[user_proxy, writer, editor], messages=[], max_round=10)
supervisor = autogen.GroupChatManager(groupchat=groupchat, llm_config=llm_config)

Begin Chat

# Provoke the chat with the consumer because the content material creator
user_proxy.initiate_chat(
  supervisor, 
  message="Write a 
brief article about synthetic
intelligence in healthcare."
)

# Kind 'exit' to terminate the chat

On this state of affairs, the consumer, represented by the UserProxyAgent, initiates a dialog to create a written article. The WriterAgent initially takes the position of drafting the content material. The EditorAgent, however, is obtainable to supply edits and strategies. The important thing right here is the Registered Auto-Reply operate, which permits the LLM to evaluate the standard of the written content material. When it acknowledges that the content material is prepared for modifying, it may well robotically change to the EditorAgent, who will then refine and enhance the article.

This dynamic dialog ensures that the writing course of is collaborative and environment friendly, with the LLM making the choice on when to contain the editor primarily based on the standard of the written content material.

LLM-Based mostly Operate Name

LLM (e.g., GPT-4) can determine whether or not to name particular features primarily based on the continuing dialog. These features can contain further brokers, enabling dynamic multi-agent conversations.

Use Case: Language Translation and Cultural Context

On this state of affairs, we have now two brokers: an Assistant Agent, which is well-versed in translating languages, and a Person-Proxy Agent representing a consumer who wants assist with a translation. The problem is not only translating phrases, but in addition understanding the cultural context to make sure correct and culturally delicate translations.

import autogen
# Outline agent configurations
config_list = autogen.config_list_from_json(
    "OAI_CONFIG_LIST",
    filter_dict={
        "mannequin": ["gpt-4", "gpt4", "gpt-4-32k", "gpt-4-32k-0314", "gpt-4-32k-v0314"],
    },
)

# Outline a operate for dynamic conversationd
# Create an assistant agent for translation
    assistant_translator = autogen.AssistantAgent(
        identify="assistant_translator",
        llm_config={
            "temperature": 0.7,
            "config_list": config_list,
        },
    )

# Create a consumer proxy agent representing the consumer
    consumer = autogen.UserProxyAgent(
        identify="consumer",
        human_input_mode="ALWAYS",
        code_execution_config={"work_dir": "consumer"},
    )123456bash

# Provoke a chat session with the 
#assistant for translation
    consumer.initiate_chat(assistant_translator, message=message)
    consumer.stop_reply_at_receive(assistant_translator)123bash

#Ship a sign to the assistant for
#finalizing the interpretation
    consumer.ship("Please present a culturally delicate translation.", assistant_translator)
    
# Return the final message acquired from the assistant return consumer.last_message()["content"]12345bash

# Create brokers for the consumer and assistant
assistant_for_user = autogen.AssistantAgent(
    identify="assistant_for_user",
    system_message="You're a language assistant. 
    Reply TERMINATE when the interpretation is full.",
    llm_config={
        "timeout": 600,
        "seed": 42,
        "config_list": config_list,
        "temperature": 0.7,
        "features": [
            {
                "name": "translate_with_cultural_context",
                "description": "Translate and ensure 
                cultural sensitivity.",
                "parameters": {
                    "type": "object",
                    "properties": {
                        "message": {
                            "type": "string",
                            "description": "Text to translate 
                            with cultural sensitivity consideration."
                        }
                    },
                    "required": ["message"],
                }
            }
        ],
    }
)

# Create a consumer proxy agent representing the consumer
consumer = autogen.UserProxyAgent(
    identify="consumer",
    human_input_mode="TERMINATE",
    max_consecutive_auto_reply=10,
    code_execution_config={"work_dir": "consumer"},
    function_map={"translate_with_cultural_context": translate_with_cultural_context},
)

# Translate a sentence with cultural sensitivity
consumer.initiate_chat(
    assistant_for_user,
    message="Translate the phrase 
    'Thanks' right into a language that reveals respect within the recipient's tradition."
)

On this use case, the consumer initiates a dialog with a request for translation. The assistant makes an attempt to supply the interpretation, however when cultural sensitivity is required, it calls the “translate_with_cultural_context” operate to work together with the consumer, who might need cultural insights. This dynamic dialog ensures that translations usually are not simply correct linguistically but in addition culturally applicable.
