The article compares four AI workflow frameworks: Prompt-based, LangGraph, Temporal, and n8n, highlighting their distinct approaches to workflow definition, state persistence, and execution engines. Prompt-based workflows use Markdown and YAML with LLM-driven routing, offering ease of modification for non-engineers but introducing non-determinism. LangGraph and Temporal leverage deterministic Python code for execution and state management, providing better testability and observability, with LangGraph integrating seamlessly with LangSmith. N8n offers a visual canvas for workflow creation, primarily supporting boolean expressions for routing. AI
