Marvin
A Python framework for extracting, classifying and generating structured data with language models, and coordinating agents through tasks and conversation threads.
About Marvin
Python applications need typed model results and a way to coordinate several AI tasks without managing conversation state by hand.
Who it’s for
- Python developers adding structured model outputs
- Teams building task-based AI workflows
When to consider it
Consider Marvin when you want typed extraction and classification alongside task and agent orchestration in Python.
Tradeoffs & limitations
- Apache-2.0 licensed; you must configure a model provider, with OpenAI used by default.
