SummaryLangChain reflects on three years of building agent systems as graphs, framing graph engineering as the latest term for structuring model reasoning within constrained paths. The post positions graphs alongside prompt, context, harness, and loop engineering as valid approaches to controlling non-deterministic LLM behavior.
Why it mattersA vendor retrospective with some firsthand framing of why graph-structured agent designs emerged, useful context for anyone choosing an orchestration pattern.
