I prompted ChatGPT, Claude, Perplexity, and Gemini and watched my Nginx logs | Hacker News

A Hacker News discussion criticized an article that tested ChatGPT, Claude, Perplexity, and Gemini by checking Nginx logs.

Commenters said the piece was poorly written and did not clearly show whether Gemini made live requests or relied on cached data.

The dispute highlights a key issue for AI assistants: whether they fetch websites in real time or answer from cached pages.

That difference affects answer freshness, what appears in server logs, and how site owners detect bot access.
