Microsoft Research’s AI Frontiers Lab has announced the release of AutoGen 0.4, a version of an open-source framework designed to build advanced AI agent systems. As reported, the latest version marks a complete redesign of the AutoGen library, focusing on enhancing code quality, robustness, usability, and the scalability of agent workflows. The update aims to establish a strong ecosystem to drive agentic artificial intelligence progress.
For readers who are unaware, AutoGen is an open-source framework developed by Microsoft Research’s AI Frontiers Lab. It simplifies the creation and management of event-driven, distributed agent applications. The framework supports multiple large language models (LLMs) and small language models (SLMs), tools, and complex multi-agent design patterns.
More about it was stated in previous Microsoft publications about AutoGen:
AutoGen supports scenarios where multiple agents interact with each other to complete complex tasks autonomously or with human oversight. The event-driven and distributed architecture makes it suitable for workflows that require long-running autonomous agents that collaborate across information boundaries with variable degrees of human involvement. AutoGen currently supports C# and Python.
The AutoGen includes several key features aimed at improving functionality and user experience. One significant feature is asynchronous messaging, which allows agents to communicate through messages that support both event-driven and request-response interaction patterns. The framework is also modular and extensible, enabling users to customize systems with pluggable components such as custom agents, tools, memory, and models. This modularity enables the development of proactive and long-running agents.
AutoGen v0.4 enforces full type support through interfaces and extensive typing, ensuring consistent and high-quality code as well as reliable application programming interfaces (APIs). The new layered architecture provides a modular approach, allowing users to target the level of abstraction that best fits their specific scenarios. Additionally, the update includes enhanced observability and debugging tools, offering capabilities for tracking, tracing, and debugging agent interactions and workflows, with support for OpenTelemetry.
Designed to be scalable and distributed, AutoGen v0.4 allows for the creation of complex agent networks that operate seamlessly across organizational boundaries. Cross-language support ensures interoperability between agents built in different programming languages, specifically Python and .NET. Furthermore, the framework supports built-in and community extensions, enabling open-source developers to manage their extensions and enhance the framework’s functionality.
The latest v0.4 update also introduces a cohesive AutoGen ecosystem, which includes the framework itself, developer tools, and applications. The framework’s layered architecture clearly defines the functionality of each layer and supports both first-party and third-party applications and extensions.

Among the developer tools included in the release are AutoGen Bench and AutoGen Studio. AutoGen Bench allows users to benchmark agents by measuring and comparing performance across various tasks and environments.
Furthermore, AutoGen Studio, rebuilt on the v0.4 AgentChat API, provides an enhanced low-code interface that enables rapid prototyping of AI agents. This tool features real-time agent updates, mid-execution control, message flow visualization, and a drag-and-drop builder.

Regarding the apps part, the release also includes Magentic-One, a new generalist multi-agent application that, as stated, is designed to solve open-ended web and file-based tasks across multiple domains.
Microsoft Research has ensured that migrating to AutoGen v0.4 is straightforward for users of the previous version. As reported, the AgentChat API maintains the same level of abstraction as in version 0.2, making it easy to upgrade existing applications.
Looking forward, Microsoft Research plans to release a .NET version of AutoGen v0.4 soon. The roadmap includes developing built-in extensions and applications and enabling a community-driven ecosystem of extensions and applications, with some already in development by users.
Lastly, the organization also indicated that more exciting features are planned, with more frequent releases expected in the future.
