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
