Fable Beats Most LLMs at Untangling a LangGraph God Node
The author pits Fable against ten other LLMs to refactor a sprawling LangGraph "god node"—a 350‑line monolith that blocks debugging and testing. By having models propose rewrites and then critique each other's suggestions, the study reveals which models excel as generators versus evaluators, giving concrete guidance for AI‑assisted code cleanup.
