This is a continuation of my last post "Leads Automation: Using LLM to estimate webpage freshness" In that post I used a function estimate_last_update_with_llm(url) to grab the contents of a webpage—or at least the first 5000 characters—and send them off to ChatGPT 4o to try to ascertain how old it thought the blog was. It was supposed to use a lot of fancy tricks to get a good idea of when it was last updated, so that I can focus my efforts on actively maintained leads instead of long-dead ghost blogs.
