LlamaIndex Workflows
Event-driven agents — connect agents via events, async + scalable.
3 hours1 resources
LlamaIndex's agent framework (formerly Agents → Workflows v1.0). Event-driven model: each step consumes an event and emits new events.
Pro: async-native, parallel branches easy. Con: mental model differs from LangGraph, learning curve.
For RAG-heavy agents, LlamaIndex's retrieval ecosystem is a big plus.
