I played around with it and its better than it used to be but if you ask it something like
"Whats the name of the third book in the peripheral trilogy going to be" it just regurgitates some dumb reddit comment by someone who seems to be making things up.
There's no actual title that has been announced and the reddit post was not a reasonable bit of speculation.
The problem with these LLMs is they rarely say "the search results were not credible no response can be provided."
These days, Google AI overviews regularly add a qualifier to the effect of "... according to this comment on Reddit <link>"
That's basically a UX trick to entirely sidestep being held accountable for the results, but seems sufficient to notify the user about the provenance of the answer to adjust their grains of salt.
