Marvin 3.0 represents a significant merger of two libraries: marvin and controlflow - re-platformed on pydantic-ai. This combined framework brings together Marvin's user-friendly structured output tools with ControlFlow's powerful agentic engine to create a simple but powerful way to get things done with AI.
