There was a fun example of this that happened live during a recent episode of the Changelog[1]. The hosts noted that they were incorrectly described as being "from GitHub" with a link to an episode of their podcast which didn't substantiate that claim. Their guest fixed the citation as they recorded[2].

How did they know it was not LLM generated?
