> LLMs got good at search last year. You need to use the right ones though - ChatGPT Thinking mode and Google AI mode (that's https://www.google.com/ai - which is NOT the same as regular Google's "AI overviews" which are still mostly trash) are both excellent.

I disagree. You might have seen some improvements in the results, but all LLMs still hallucinate quite hard on simple queries where you prompt them to cite their sources. You'll see ChatGPT insist quite hard that the source of their assertions is the 404 link that it asserts is working.

This is just completely the opposite to what i've experienced within Claude and Gemini. Sources are identified and if inaccessible are not included in the citations. I recently tried a quite specific search aimed towards finding information about specific memo's and essays cited within a 90s memo by bill gates, and it was succesful at finding a vast majority of them, something google search failed with.

I don't want to say that it's a skill issue, but you may just be using the wrong tools for the job.
