Right. Try clicking those sources, half the time there is zero relation to the sentence. LLMs just output what they want to say, and then sprinkle in what the web search found on random sentences.

And not just bottom of the barrel LLMs. Ask Claude about Intel PIN tools, it will merrily tell you that it "Has thread-safe APIs but performance issues were noted with multi-threaded tools like ThreadSanitizer" and then cite the Disney Pins blog and the DropoutStore "2025 Pin of the Month Bundle" as an inline source.

Enamel pins. That's the level of trust you should have when LLMs pretend to be citing a source.
