Background: Overview of Core Concepts

What is AutoGen? 

AutoGen is an innovative, open-source framework developed by Microsoft to streamline the creation, management, and orchestration of AI agents. This framework is designed to enable AI agents to collaborate effectively, leveraging their specialized capabilities to solve complex, multi-faceted problems that would be challenging for a single AI system to address independently.

It is particularly valuable in scenarios requiring diverse expertise or task segmentation, as it allows agents to communicate and share information dynamically. AutoGen improves efficiency, scalability, and problem-solving depth by fostering collaboration between agents in AI-powered solutions. 

Why Multi-Agent Orchestration? 

A multi-agent system has many advantages: 

• Specialized Expertise: Agents can specialize in different tasks, which may allow for more efficient processing in the respective area. 

• Scalability: Multi-agent systems can share workloads among several agents, so operation scalability is seamless as demand grows without degradation in performance. 

• Redundancy: The agents provide redundancy, which ensures better reliability. In cases of failure, the system easily compensates with other agents to reduce downtime. 

• Flexibility: Such systems can "readily incorporate new capabilities or agents"; thus, it becomes relatively easy for organisations to easily adapt themselves rapidly to changing needs or technological advancements. 
  
  

Implementation of Multi-Agents Framework with AutoGen

Implementing AutoGen involves setting up the environment, creating and configuring agents, and orchestrating their interactions to perform complex tasks. 

Step 1: Setting Up the Environment 

To get started, you need to install AutoGen and its dependencies using pip: 

pip install autogen 
pip install autogen-agentchat

Step 2. Importing Required Libraries 

Explain the libraries and modules used in the project, specifically the AutoGen library and its components, which help define agents and workflows. 

import autogen 
from autogen import ConversableAgent, AssistantAgent, UserProxyAgent 
from autogen import config_list_from_json

Step 3. Setting Up the Configuration 

Discuss the need for LLM configuration and demonstrate how to define it using custom settings like API type, model, and API key. 

llm_config = { 
    "api_type": "groq", 
    "base_url": "https://api.groq.com/openai/v", 
    "model": "", 
    "api_key": "" 
}

Step  4. Defining the Agents 

Describe the purpose of each agent, including their roles in the diagnostic process. Include the code for setting up agents with system messages, configuration, and human input modes. 

Symptom Collection Agent 

symptom_collection_agent = ConversableAgent( 
    name="Symptom Collection Agent", 
    system_message='''You are responsible for collecting detailed symptom information from the patient.  
    Ask relevant questions and ensure all symptoms are recorded accurately.  
    Return 'TERMINATE' when you have gathered all the information.''', 
    llm_config=llm_config, 
    code_execution_config=False, 
    human_input_mode="ALWAYS", 
)

Medical History Agent 

medical_history_agent = ConversableAgent( 
    name="Medical History Agent", 
    system_message='''You are responsible for gathering and reviewing the patient's medical history.  
    Ask about past illnesses, surgeries, and any relevant medical information.  
    Return 'TERMINATE' when you have gathered all the information.''', 
    llm_config=llm_config, 
    code_execution_config=False, 
    human_input_mode="ALWAYS",)

Step 5. Creating the User Proxy Agent 

A user proxy agent is defined as something that acts as a human in a loop, and we demonstrate here how it interacts with other agents to simulate user input. 

user_proxy = UserProxyAgent( 
    name="User", 
    human_input_mode="ALWAYS", 
    is_termination_msg=lambda x: x.get("content", "").find("TERMINATE") >= 0, 
    code_execution_config={ 
        "last_n_messages": 1, 
        "work_dir": "tasks", 
        "use_docker": False, 
    }, 
) 

Step 6. Defining Nested Chats (Optional) 

Show how you structure conversations using nested chats, each focusing on a specific agent's task, and summarize the results. 

chats = [ 
    { 
        "recipient": symptom_collection_agent, 
        "message": "Please start collecting the patient's symptoms.", 
        "summary_method": "reflection_with_llm", 
        "summary_args": { 
            "summary_prompt": "Summarize the collected symptoms as JSON: {'symptoms': []}", 
        }, 
        "max_turns": 1, 
        "clear_history": True 
    }, 
    # Additional chat tasks for other agents 
]

Step 7. Coordinating with the Primary Diagnostic Agent 

Now, we show how the primary_diagnostic_agent oversees the workflow and ensures tasks are executed in sequence. 

primary_diagnostic_agent = AssistantAgent( 
    name="Primary Diagnostic Agent", 
    system_message='''You are responsible for coordinating the diagnostic workflow.  
    Ensure that the symptom collection, medical history, diagnostic analysis,  
    and treatment recommendation agents complete their tasks in sequence.''', 
    llm_config=llm_config, 
    code_execution_config=False, 
    human_input_mode="NEVER", 
) 
primary_diagnostic_agent.register_nested_chats(chats, trigger=user_proxy)

Step 8. Initiating the Workflow 

After we have defined all the agents for the diagnostic workflow, we start and provide a sample interaction. 

querytask = "What brings you in today?" 
chat_results = primary_diagnostic_agent.initiate_chat( 
    recipient=user_proxy,  
    message=querytask,  
    max_turns=2,  
    summary_method="last_msg" 
)
