Though a local model I'm running (gemma-3-27b-it; https://huggingface.co/lmstudio-community/gemma-3-27b-it-GGU...) just told me various correct sounding bits about his history with alcohol (correctly citing his alma mater and first wife), but threw in:
"Sobriety & AA: Newman got sober in 1964 and remained so for the rest of his life."
Which doesn't check out. And it includes plausible but completely hallucinated URLs (as well as a valid biography.com URL that completely omits information about alcohol.)
