Autogen - AI Agents Framework

Microsoft is now part of the competition for Large Language Model (LLM) application structures with its open-source Python library called AutoGen. In Microsoft's words, AutoGen serves as "a system designed to make easier the management, enhancement, and automation of LLM processes." The basic idea behind AutoGen involves making "agents," which are code modules driven by LLMs like GPT-4. These agents communicate with one another using natural language messages to accomplish a variety of tasks.

Agents can be personalized and enhanced with prompt engineering methods and additional tools. These improvements let them fetch information or run code effectively. Using the AutoGen platform, developers have the ability to create a system of agents focusing on various tasks while working together in harmony.

What are LLM Agents?

Language models of the vanilla type do many things wonderfully, like translating and answering questions. But their understanding and ability have limits. It is similar to a builder lacking tools while constructing a home. Nevertheless, it has been noticed that LLMs have the ability to think and operate when provided with essential instruments. The majority of the LLMs possess restricted understanding of the world, but it is possible to enhance them with data from special sources through prompting.

We can achieve this via two methods. Retrieval, augmented generation, and LLM agents. In RAG, we provide models with data through specially designed pipelines. But when it comes to agents, the LLM will utilize a tool that is available based on its own reasoning process. For instance, GPT-4 using a Serper tool can search the internet and give answers in line with that, or it can check and evaluate stock performance if it has the availability of the Yahoo Finance tool. Thus, this joining of LLMs, tools, and a setup for thinking and taking action is what we call an AI agent.

Platforms and tools for constructing LLM agents have swiftly increased. One of these tools is Autogen. So, let us start with an overview of Autogen and how to use it to create LLM agents.

What is Autogen?

Autogen is a tool that Microsoft has made open-source for creating multi-agent applications of solid strength. The design was done from the very start, considering communication between multiple agents. This allows us to construct LLM applications where several agents communicate with each other to seek answers to the given challenges.

Scenario 1: Auto-Generated Agent Chat Teaching

In this sample, we will discover how AutoGen supports teaching of AI actors via normal talks. We are going to make agents that learn fresh abilities and create repeatable instructions for upcoming duties. This sample shows how adaptable and multi-talented AutoGen is in enhancing the abilities of AI systems.

Setting Up AutoGen

You should perform the steps detailed in Example 1 for establishing AutoGen and organizing the essential API endpoint. You need to bring in the AutoGen library and form an LLM config following your needs.

Teaching AI new skills

Use AutoGen for teaching AI agents fresh skills by way of agent communications. Set the required skills and direct the agents during talks to gain needed knowledge. Use present APIs or libraries to get information, do tasks and make results according to what the user asks. Talk with AI agents back and forth for making better their understanding and increasing how well they work.

Creating a Reusable Recipe

After you finish the task successfully, make a repeat-use recipe which captures all steps and their related coding logic. Build Python functions for doing similar tasks in future times, making sure there is clear division between coding and non-coding procedures. By making properly recorded and broad functions, the recipe can be used again in an efficient manner for similar work without initiating from the beginning.

Scenario 2: Automated Task Solving with Code Generation

After you have installed it, bring in the AutoGen library and arrange an API endpoint for reaching your preferred models. Set up the LLM configuration according to your liking, such as by choosing mode, adjusting temperature, and so on.

Defining Agents

You must identify the essential agents for your work, like the helper agent and the user representative agent. The helper agent uses LLM-based skills to create code and give advice, whereas the user representative agent acts on behalf of the user and can autonomously run code. Please describe how the agents interact with each other and when they should ask for input from the user or continue to function automatically.

Executing Code and Debugging

Apply the specified agents to run code and see the result. During this execution, there can be several interactions between agents where user proxy agent operates the code giving back responses. If problems or faults appear, the helping agent can find mistake in code and propose betterments. Working together to correct mistakes guarantees more precise outcomes and superior quality of code.

Displaying the Output

When the code runs successfully, it creates an output that we can show in a good format. Here, Python's matplotlib library is useful for making a bar Chart to present the necessary details. The agent of user proxy runs the code for making chart. The file that is created can be kept and shown for analysis in future.
