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
Pydantic AI
- +Strong type safety and schema-validated outputs from the Pydantic team
- +Built-in reflection and self-correction on invalid output
- +Model-agnostic across most major providers; integrates with Logfire observability
- -Python-only
- -A framework, not a product: you build, host, and secure your agents
