AIRFLOW-AI-SDK

This repository contains an SDK that allows users to call large language models and orchestrate agent calls directly within Apache Airflow pipelines using decorator-based tasks. It can be used to define tasks that call language models to process text, organize straight multi-step AI reasoning, automatically parse and validate outputs, and change the control flow of a DAG based on output. The SDK supports all models in the Pydantic AI library.
