The summary on here says that, but the actual article says it was Meta's.

In one eyebrow-raising example, Meta's large language model Llama 3 told a user who identified themself to it as a former addict named Pedro to indulge in a little methamphetamine — an incredibly dangerous and addictive drug — to get through a grueling workweek.

Might have been different in a previous version of the article, then updated, but the summary here doesn't reflect the change? I dunno.
