In this video tutorial, Nate Herk showcases four specialized frameworks—prompt chaining, routing, parallelization, and evaluator optimizer—built using an n8n system. The workflows demonstrate sequential processing for blog generation, email classification with Gmail, Telegram alerts for high priority tasks, parallel data analysis with distinct LLMs, and an iterative optimization loop that refines outputs via Google Docs integration. Free templates for these agent-driven workflows are available in the community.
