MARVIN

Type-safe AI functions and agents in pure Python

Apache-2.0

ABOUT

Integrating LLMs into production Python applications is hard because LLM outputs are unstructured, unpredictable, and difficult to validate. Marvin solves this by providing type-safe, structured outputs from AI models using Pydantic, and an intuitive framework for building multi-step agentic workflows. It eliminates manual prompt engineering for consistent data formats and provides observability and control over complex AI agent coordination.

INSTALL
pip install marvin

INTEGRATION GUIDE

1. Cast, classify, extract, and generate structured data from any inputs using LLMs with type safety 2. Create specialized AI agents with distinct skills and personalities for task-specific problem solving 3. Orchestrate multi-agent workflows by composing discrete observable tasks into threads 4. Build AI-powered Slack bots and conversational assistants with structured conversation management 5. Generate validated Pydantic models from unstructured text for reliable downstream processing
