Key Points

  • The article presents a practical workflow for classifying unstructured, messy free-text into predefined categories using a locally hosted LLM.
  • It emphasizes a zero-shot approach that does not require labeled training data for model setup or fine-tuning.
  • The focus is on making local inference work as a labeling pipeline for downstream categorization tasks.
  • The method is positioned as a convenient way to turn free-form text into meaningful, structured categories without additional supervised data.

A practical pipeline for classifying messy free-text data into meaningful categories using a locally hosted LLM, no labeled training data required.
