Agent’s concepts behind AutoGen

AutoGen abstracts and implements conversable agents designed to solve tasks through inter-agent conversations. Specifically, the agents in AutoGen have the following notable features:

  • Conversable: Agents in AutoGen are conversable, which means that any agent can send and receive messages from other agents to initiate or continue a conversation
  • Customizable: Agents in AutoGen can be customized to integrate LLMs, humans, tools, or a combination of them.

The figure below shows the built-in agents in AutoGen.

The agents ConversableAgent, AssistantAgent, UserProxyAgent, and GroupChatManager are classes provided within the AutoGen framework, a system by Microsoft for facilitating multi-agent conversations in large language models (LLMs). Here’s a detailed breakdown of these agents:

  1. ConversableAgent:
  • A generic class designed for agents capable of conversing with each other through message exchange to complete a task.
  • Agents can communicate with other agents and perform actions, with their efforts potentially differing based on the messages they receive.
  • Provides an auto-reply capability for more autonomous multi-agent communication while retaining the option for human intervention.
  • Extensible by registering reply functions with the register_reply() method.
  1. AssistantAgent:
  • Acts as an AI assistant using LLMs by default, without requiring human input or code execution.
  • Can write Python code for a user to execute when a task description message is received, with the code generated by an LLM like GPT-4.
  • Receives execution results and suggests corrections or bug fixes if necessary.
  • Its behavior can be altered by passing a new system message, and LLM inference configuration can be managed via llm_config.
  1. UserProxyAgent:
  • Serves as a proxy agent for humans, soliciting human input for the agent’s replies at each interaction turn by default while also having the ability to execute code and call functions.
  • Triggers code execution automatically upon detecting an executable code block in the received message when no human user input is provided.
  • Code execution can be disabled, and LLM-based responses, which are disabled by default, can be enabled via llm_config. When llm_config is set as a dictionary, the UserProxyAgent can generate replies using an LLM when code execution is not performed.
  1. GroupChatManager:
  • A class inherited from ConversableAgent, designed to manage a group chat involving multiple agents.
  • Provides a method run_chat to initiate and manage a group chat, with parameters for messages, sender, and configuration.
  • This class appears to be in preview, indicating it might be a newer or less stable feature of AutoGen.

In practical terms, these agents facilitate complex workflows and interaction patterns among multiple entities, be they other AI agents, human users, or a combination of both. For example, the GroupChatManager could potentially moderate conversations between agents and humans, passing messages according to specific rules.

Examples of Various Applications Executed with AutoGen

The figure below shows six examples of applications built using AutoGen.

Here are some of AutoGen examples:

A Rising Competitive Arena

The domain of Large Language Model (LLM) application frameworks is swiftly evolving, with Microsoft’s AutoGen contending robustly amidst many competitors. LangChain is a framework for constructing a diverse range of LLM applications, spanning chatbots, text summarizers, and agents. At the same time, LlamaIndex provides abundant tools for interfacing LLMs with external data reservoirs like documents and databases.

Similarly, libraries such as AutoGPT, MetaGPT, and BabyAGI rely on LLM agents and multi-agent application spheres. ChatDev employs LLM agents to mimic a full-fledged software development team. Concurrently, Hugging Face’s Transformers Agents library empowers developers to craft conversational applications that bridge LLMs with external tools.

The arena of LLM agents is a burgeoning focal point in research and development, with early-stage models already devised for a spectrum of tasks, including product evolution, executive functionalities, shopping, and market analysis. Research has unveiled the potential of LLM agents in simulating mass populace behaviors or generating realistic, non-playable personas in gaming environments. Yet, a substantial portion of this endeavor remains in the proof-of-concept stage, not quite ready for full-fledged production due to hurdles like hallucinations and erratic behavior exhibited by LLM agents.

Nonetheless, the outlook for LLM applications is promising, with agents poised to assume a pivotal role. Major tech entities are placing substantial bets on AI copilots becoming integral components of future applications and operating systems. LLM agent frameworks will allow companies to design customized AI copilots. The foray of Microsoft into this burgeoning arena with AutoGen underscores the escalating competition surrounding LLM agents and their prospective future impact.
