A simple way to create test sets for your LLM blocks in n8n
How to build a testing workflow inside n8n
Refining prompts in n8n to get repeatable results
Why this topic matters
Building n8n automations with LLM blocks is quite popular, yet a lot of people struggle with getting those blocks to behave consistently.
