What is AutoGen?

Discover how AutoGen can enhance your workflow

AutoGen provides a programmable way to compose multiple AI agents that can converse plan call tools and hand off work. Developers define agents with roles and capabilities then register functions APIs or code execution as tools the agents may request. A conversation loop coordinates messages and tool calls including explicit handoffs to a human when needed. The framework includes examples for retrieval augmented generation data processing and coding assistants and supports both deterministic scripted exchanges and dynamic decision making. A companion set of extensions helps with memory logging evaluation and UI. Because AutoGen is open source teams can self host choose models and integrate with existing stacks while keeping observability through traces. Microsoft now recommends its newer Agent Framework for many scenarios yet AutoGen remains maintained for fixes and remains widely used in research and prototypes that evolve into production when governance and controls are added.

Does Microsoft still recommend it?
It is maintained with fixes while Microsoft points many new projects to the newer Agent Framework for greenfield builds.
Which models can I use?
You can call popular hosted or local models through adapters and standard Python clients.
Can agents run code?
You can register code execution and external tools with safeguards and resource limits.
Does it work with retrieval?
Yes extensions and examples show how to ground answers with vector stores and document loaders.
How do I monitor agents?
Use logging and tracing hooks to capture steps tools costs and outcomes for review.
Is there a UI?
Starter chat UIs and notebooks help teams demo flows before building custom front ends.
Can I deploy to production?
Teams often start in notebooks then containerize services with observability and policy controls for production.
