# ScrapingBee publishes tutorial on self-reviewing LLM code generation loops for web extraction

> ScrapingBee published a blog post walking through the implementation of a self-reviewing code generation loop where an LLM writes extraction code, runs it against real HTML, checks the output, and revises the code on failure.

## Briefing
- ScrapingBee: ScrapingBee published a blog post walking through the implementation of a self-reviewing code generation loop where an LLM writes extraction code, runs it against real HTML, checks the output, and revises the code on failure.

## Why it matters
This tutorial addresses a practical challenge in using LLMs for web scraping: ensuring generated extraction code actually works. By automating the verification and revision cycle, it points toward more reliable, self-correcting extraction pipelines that reduce manual debugging, which is a key concern for developers building AI-driven scrapers.

## Watch next
Will self-reviewing loops become a standard pattern in LLM-based extraction tooling, or will they remain a niche technique for complex selectors?
