Aren't people just asking Claude and/or Gpt to do web searches instead? I had for quite some time only relied on o3 pro for every query and it always defaulted to web search so hallucination rate was (seemingly) very low. Now I'm using Claude more and he (it?) needs to be reminded that it he has a web saerch tool but other than that it works great.
