What's different is that LLMs with search tools used to be terrible - they would run a single search, get back 10 results and summarize those.

Often the results were bad, so the answer was bad.

GPT-5 Thinking (and o3 before it, but very few people tried o3) does a whole lot better then that. It runs multiple searches, then evaluates the results and runs follow-up searches to try to get to a credible result.

This is new and worth writing about. LLM search doesn't suck any more.

Like I said I have nothing against the blog post or writing about it, that was by no means meant as a criticism of you. And I agree it's worth writing and talking about. What surprises me is that we're in a forum for technology enthusiasts.

FWIW Gemini at least has been pretty good at this since late 2024 IMO.

As for where things are now, I just ran a comparison with ChatGPT 5 in thinking mode against Google search's AI mode across a few questions. They performed the same on the searches I tried and returned substantially the same answer except for some minor variation here or there. Google search is maybe an order of magnitude faster. Google obviously has an advantage here which is that it has full access to their search and ranking index.

And of course the ability to make multiple searches and reason about them for been available for months, maybe almost a year, as deep research mode. I guess the novelty now is you can wait a smaller time and get research that's less deep.
