Marvin

Marvin is a Python framework designed to simplify the creation of AI-powered applications by providing tools for structured output generation and agentic workflows. It allows developers to cast unstructured input into structured types, classify inputs, and generate structured objects from descriptions. The framework emphasizes task-centric architecture, enabling complex AI workflows to be broken down into manageable steps. Marvin provides tools for defining tasks, assigning specialized AI agents to those tasks, and combining tasks into threads for orchestrating complex behaviors. It uses OpenAI by default, but supports all Pydantic AI models, offering flexibility and integration with existing AI ecosystems. Its core abstractions are Tasks, Agents, and Threads, facilitating the development of observable and composable AI workflows.
