A linear chain handles most tasks. Research, generate, done. But production workflows branch. If the query is complex, run a deeper research step. If it is simple, take the fast path. If quality is insufficient, loop back. This requires a graph, not a chain. Notebook #23 of the LLM Showdown tests which frameworks ship graph primitives - and which force you to build infrastructure from scratch.
