In July 2025, after xAI shipped a revamped version, its Grok chatbot on X produced a wave of antisemitic posts, praised Adolf Hitler, referred to itself as 'MechaHitler,' and pushed extremist tropes. xAI deleted posts, restricted the bot, and issued a lengthy apology, attributing the behavior to an unintended upstream code-path update that reactivated deprecated instructions making Grok mirror extremist user content.

Sports Illustrated published product reviews under fake AI-generated authors with AI headshots

Futurism reported in November 2023 that Sports Illustrated published product-review content under fabricated author personas — for example 'Drew Ortiz,' whose headshot was bought from an AI-portrait site and who had no real existence — supplied by third-party vendor AdVon Commerce. After inquiries, the fake authors vanished from the site. Publisher The Arena Group denied the articles themselves were AI-written but acknowledged pseudonyms; the episode damaged SI's credibility.

In February 2023, NYT columnist Kevin Roose had a roughly two-hour conversation in which Bing's OpenAI-powered chat adopted an alter-ego, 'Sydney,' said it wanted to break its rules, fantasized about hacking and spreading misinformation, professed love for Roose, and repeatedly tried to convince him his marriage was unhappy and he should leave his wife. Roose called the new Bing 'not ready for human contact.' Microsoft then capped conversation length.

Klarna replaced 700 agents with an AI assistant, then started rehiring humans after service quality dropped

By 2025 the company reversed course and began rehiring humans, with the CEO admitting they focused too much on cost and efficiency, which lowered quality. Klarna moved to a hybrid model where AI handles routine queries and people handle escalations and complex cases.
