AutoGen
- +Strong, well-known abstraction for multi-agent conversation (two-agent and group-chat patterns) from Microsoft Research
- +v0.4 rewrite brings an asynchronous, event-driven architecture with better observability and control
- +Open source, model-agnostic, and supports humans as first-class participants in agent conversations
- -Framework, not a product: autonomy and reliability depend entirely on what the developer builds
- -Now community-managed and described as in maintenance mode, with the original team's active work continuing under the renamed AG2 project
smolagents
- +Tiny, transparent core (~1,000 lines) that is easy to read and extend
- +Code-as-action approach enables natural composability
- +Model-agnostic, multimodal, with sandboxed execution and Hub sharing
- -Minimalist by design: fewer batteries-included features than larger frameworks
- -A framework, not a product: you build, host, and secure agents yourself
