LlamaIndex Supervisor is a developer-focused Python framework designed to create, run, and monitor AI agents built on LlamaIndex. It provides tools for defining workflows as nodes—such as retrieval, summarization, and custom processing—and wiring them into directed graphs. The Supervisor oversees each step, validating outputs against schemas, retrying on errors, and logging metrics. This ensures robust, repeatable pipelines for tasks like retrieval-augmented generation, document QA, and data extraction across diverse datasets.
