What is AutoGen?

AutoGen is an open-source framework from Microsoft that enables you to build applications using multiple AI agents that communicate with each other. Instead of working with a single LLM, you create specialise agents that can take on different roles, ask questions of each other, and work together to solve problems. This is particularly useful for complex tasks that benefit from different perspectives or expertise. The framework handles the conversation flow between agents, manages LLM calls, and lets you define when agents should hand off work to each other. It's designed for developers who want to move beyond simple prompt-response interactions and build systems where AI agents actively collaborate.

Key Features

Multi-agent conversation framework

Define multiple AI agents with different roles and capabilities that interact with each other

Configurable agent behaviour

Set instructions, tools, and stopping conditions for each agent

Tool integration

Connect agents to external APIs, code execution environments, and data sources

Conversation management

Automatic handling of message flow, context, and turn-taking between agents

Support for multiple LLM providers

Compatible with OpenAI, Azure OpenAI, and other model providers

Code execution

Agents can write and execute code to solve problems or validate solutions

Pros & Cons

Advantages

  • Open source and free to use, with active development and community support
  • Flexible design lets you create complex workflows without building conversation logic from scratch
  • Works with multiple LLM providers, so you're not locked into one service
  • Good documentation and examples for common use cases like data analysis and code generation

Limitations

  • Requires development experience to set up and configure agents effectively
  • Can become expensive at scale if using paid LLM APIs, as multi-agent systems make more API calls
  • Debugging agent interactions can be challenging when things don't work as expected

Use Cases

Data analysis workflows where one agent gathers data and another analyses it

Software development tasks where agents collaborate on code generation and testing

Customer service systems that route inquiries between specialist agents

Research and information gathering where agents explore sources and synthesise findings

Complex problem-solving requiring multiple perspectives or expertise areas
