An AI transcription tool used in health care has been found to frequently hallucinate things no one ever said, including making up medications. That’s just one of the topics for today’s Marketplace Tech Bytes: Week in Review. Plus, we’ll get into what we learned from this week’s Big Tech earnings, including Google saying that it’s using artificial intelligence to generate about 25% of its code.

But first, it’s been a busy week for Apple. The company launched some of its new Apple Intelligence features and released its new lineup of Mac computers along with some souped-up chips.

Marketplace’s Meghan McCarty Carino spoke with Joanna Stern, senior personal technology columnist at The Wall Street Journal, to get her take on this week’s tech news.
