LlamaIndex Workflows
the right pick when the agent is rag- and data-heavy
an event-driven, 1.0-stable workflow runtime sitting on the strongest rag stack — the natural choice when retrieval, not orchestration, is the hard part of your agent.
llamaindex workflows model an agent as steps that consume and emit typed events, with the runtime routing events to subscribing steps — an async-first, clean event model that reached its first stable 1.0 release. its real advantage is what it sits on: llamaindex's data and rag stack, so when your agent is fundamentally retrieval-over-your-data, this is the most natural home. agentworkflow orchestrates multiple agents over the same event bus.
the trade-off is package sprawl — the broader llamaindex surface is large — and it reads more as a data framework with agents than a pure agent runtime. cross-provider, and strongest for data-centric agents.
