GPT & Web Crawlers

GPTs like GPT4 are an excellent addition to web crawlers. GPT4 is more capable than GPT3.5, but not as cost effective especially in a large-scale web crawling context.

There are a number of ways to use GPT3.5 & GPT 4 in web crawlers, but the most common use for us is data analysis. GPTs can also help address some of the issues with large-scale web crawling.
