## Summary

A new tutorial demonstrates how to build custom Named Entity Recognition (NER) pipelines using the Scikit-LLM library. The guide shows developers how to leverage Large Language Model (LLM) reasoning to extract structured data from unstructured text without the need for extensive training datasets or fine-tuning. 

The example uses Groq's free-tier API to run the open-source model `openai/gpt-oss-20b` within a Google Colab notebook. By defining a simple entity dictionary with descriptions, the `GPTExplainableNER` estimator processes raw text to identify categories such as executives, corporations, products, and cities. The results show that while raw LLM outputs can be messy, simple post-processing with regular expressions yields clean, structured data. 

This approach offers a low-code alternative to traditional NLP libraries, allowing users to implement domain-specific extraction tasks with minimal configuration. The method relies on the reasoning capabilities of pre-trained models rather than supervised learning, making it accessible for quick prototyping and data analysis tasks.

## Key points

- Scikit-LLM allows building custom NER pipelines using LLM reasoning without fine-tuning.
- The tutorial uses Groq's free API and the openai/gpt-oss-20b model in Google Colab.
- Raw LLM outputs require regex post-processing to achieve clean, structured entity extraction.

## Why it matters

It provides a low-cost, low-code method for extracting structured data from text, reducing the barrier to entry for NLP tasks that traditionally require large datasets and specialized expertise.
