Strengths	+ Extensive data connectors and RAG tooling + Strong document parsing and ingestion (LlamaParse/LlamaCloud) + Agents and event-driven workflows built in + Large ecosystem and integrations	+ Deep integration with OpenAI features + Built-in handoff and guardrail primitives
Tradeoffs	− Broad API surface can be complex to navigate − Heritage is RAG-centric rather than agent-first − Frequent API changes across versions	− OpenAI-first; cross-provider use is awkward
