Workflows

A Workflow in LlamaIndex is an event-driven abstraction used to chain together several events. Workflows are made up of steps, with each step responsible for handling certain event types and emitting new events.

You can create a Workflow to do anything! Build an agent, a RAG flow, an extraction flow, or anything else you want.

Workflows are also automatically instrumented, so you get observability into each step using tools like Arize Pheonix. (NOTE: Observability works for integrations that take advantage of the newer instrumentation system. Usage may vary.)

!!! important The Workflows library can be installed standalone, via pip install llama-index-workflows. However, llama-index-core comes with a stable version of Workflows included.

When installing `llama-index-core` or the `llama-index` umbrella package, Workflows can be accessed with the import
path `llama_index.core.workflow`. In order to maintain the `llama_index` API stable and avoid breaking changes,
the Workflows library version included is usually older than the latest version of `llama-index-workflows`.

At the moment, the latest version of `llama-index-workflows` is 2.0 while the one shipped with `llama-index` is
1.3
