AutoGen: Building Agentic Chatbots with AI Agents

Chatbots have revolutionized human-computer interaction, enabling intelligent conversations across numerous applications. However, creating flexible and scalable chatbot systems can be complex. AutoGen simplifies this process by leveraging AI agents to manage intricate dialogues and tasks independently. This article demonstrates how to build sophisticated chatbots using AutoGen's agent-based framework.

Key Features of AutoGen:

• Understand AutoGen's capabilities and functionality.
• Create chatbots capable of engaging in discussions, responding to user queries, performing web searches, and more.
• Learn the setup and prerequisites for building AutoGen-based chatbots.
• Enhance chatbots by integrating tools like Tavily for web searches.

What is AutoGen?

AutoGen models interactions as conversations between autonomous AI agents. This agent-to-agent communication simplifies development, facilitating intuitive chatbot creation. The framework supports diverse conversation styles, including sequential and group chats.

This article explores three chatbot types:

1. Agent Dialectic: Two AI experts debate a topic, aiming to resolve conflicting viewpoints.
2. Interview Preparation Bot: An agent simulates an interview, posing questions and evaluating responses.
3. Web Search Integration: A chatbot interacts with a web search tool (Tavily) to retrieve information.

Prerequisites:

Before building AutoGen agents, obtain API keys for LLMs (like OpenAI and Groq, which offers free access to several open-source LLMs). You'll also need a Tavily API key for web searches. Store these keys securely in a .env file.

Required Libraries:

• autogen-agentchat (version 0.2.36)
• tavily-python (version 0.5.0)
• groq (version 0.7.0)
• openai (version 1.46.0)

Agent Dialectic Example:

This example demonstrates a dialectic between two agents debating the privacy risks of AI model training data. Two ConversableAgent objects are created, each with a specific system message defining their role (pro and con arguments). The initiate_chat method starts the conversation, and the chat_history and summary attributes provide access to the conversation and its summary.

Interview Preparation Bot Example:

This example creates an "interviewer" agent and a "candidate" agent. The interviewer asks questions, and the candidate (controlled by human input) provides answers. The human_input_mode="ALWAYS" setting ensures the candidate's responses come from a human user.

Web Search Integration Example:

This example integrates the Tavily web search tool. A web_search function uses the Tavily API, and this function is registered with AutoGen using register_function. An assistant agent decides when to use the tool, and a user proxy agent executes the tool calls.

Conclusion:

AutoGen simplifies agentic chatbot development, offering flexibility and scalability. Its agent-based architecture enables complex interactions and seamless tool integration. AutoGen empowers developers to create engaging and informative chatbots for a wide range of applications.
