LlamaIndex Workflows

LlamaIndex Workflows is an event-driven orchestration framework from the LlamaIndex team, designed for building AI agent pipelines around document-heavy and data-intensive use cases such as retrieval-augmented generation, document processing, and knowledge-base question answering. Rather than a rigid graph, workflows are defined as a series of steps that react to events, making it easier to model branching logic, parallel processing, and human-in-the-loop checkpoints within a single pipeline. Because it builds on LlamaIndex's existing strengths in data ingestion, indexing, and retrieval, LlamaIndex Workflows is a natural fit for teams whose agents need to reason over large internal document collections rather than primarily call external APIs or tools.
