Inside the company behind Claude, researchers are trying to understand systems that may have already exceeded their grasp. The staff writer Gideon Lewis-Kraus joins Tyler Foggatt to discuss his reporting on Anthropic, the artificial-intelligence company behind the large language model Claude. They talk about Lewis-Kraus's visits to the company's San Francisco headquarters, what drew him to its research on interpretability and model behavior, and how its founding by former OpenAI leaders reflects deeper fissures within the A.I. industry. They also examine what "A.I. safety" looks like in theory and in practice, the range of views among rank-and-file employees about the technology's future, and whether the company's commitment to building safe and ethical systems can endure amid the pressures to scale and compete. Anthropic Doesn't Know, Either," by Gideon Lewis-Kraus " Is There a Remedy for Presidential Profiteering?

Finally, he gave the summaries to his fine-tuned model, and he asked it to compose passages "in the style of Vauhini Vara." Going into all this, I was self-assured, even smug. I'd always felt that my style was original and, more important, that my books were totally distinct from one another. I figured that, even if the A.I. model could imitate my past books, it couldn't predict the style of the novel in progress. So, when Chakrabarty sent me the A.I.-generated imitations, I was genuinely confused.

After the rapper's 1979 hit "Christmas Rappin'," his song "The Breaks" was the first rap single to go gold. In a rehearsal studio in the Echo Park neighborhood in Los Angeles, Kurtis Blow was limbering up and getting loose. Earlier this year, his left arm swelled up abruptly, requiring four surgeries to resolve what was eventually diagnosed as deep-vein thrombosis. Blow usually holds the mike in his right hand when he raps, but he had to get his left arm going, he said, "because it's my'Throw your hands in the air' arm." Lithe at age sixty-six, Blow was dressed in leather cargo pants, a track jacket, and a black baseball cap with the words " above its brim. He was whipping himself into shape for a "Legends of Hip-Hop" concert to be held just after Thanksgiving at the Peacock Theatre, in downtown L.A. He will be on a stage that will also feature such foundational rappers as Big Daddy Kane, Doug E. Fresh, and two members of the Furious Five, Melle Mel and Scorpio. Blow's youngest son, Michael, the studio's owner, manned the d.j. The rapper's eldest, Kurtis, Jr., nodded his do-ragged head to the beat and offered counsel alongside his mother, Kurtis, Sr.,'s wife of forty-two years, Shirley. It has been forty-five years since the release of Blow's song "The Breaks," the first rap single to be certified gold. Blow had already scored a novelty hit, "Christmas Rappin'," at the end of 1979, the watershed year in which rap transitioned from clubs in the Bronx and Harlem to singles pressed on vinyl, chief among them "Rapper's Delight," by the Sugarhill Gang. "I had a singles deal with escalating options," Blow recalled. "I had to sell thirty thousand records in order to do another single.

Our columnist on digital culture suggests technology--or anti-technology technology--to give this holiday season. We are entering a Surrealist phase of personal technology. Any device you might imagine can be found online courtesy of an obscure Chinese factory, ready to be shipped out for a loved one's holiday enjoyment: pocket-size artificial-intelligence gizmos ( Rabbit r1, $199), in-home hologram machines (Code 27 Character Livehouse, $558), human-size robot servants ( 1X NEO, $20,000). The components of tech have become better and cheaper, from microchips to speakers and screens (have you seen how cheap a good TV is these days?), enabling out-there innovation. On the consumer side, we are bored of rote device designs; we've seen a dozen models of iPhone and crave something refreshingly different.

When President Donald Trump began his tariff rollout, the business world predicted that his unprecedented attempt to reshape the economy would lead to a major recession, if he went through with it all. But the markets stabilized and, in recent months, have continued to surge. That has some people worried about an even bigger threat: that overinvestment in artificial intelligence is creating a bubble . Andrew Ross Sorkin, one of today's preëminent financial journalists, is well versed in what's happening; his début book, " Too Big to Fail," was an account of the 2008 financial crash, and this year he released " 1929: Inside the Greatest Crash in Wall Street History--and How It Shattered a Nation ." He tells David Remnick that the concern lies in the immense borrowing to build the infrastructure for a future A.I. economy, without the sufficient revenue, currently, to pay off the loans.

That New Hit Song on Spotify? Aspiring musicians are churning out tracks using generative artificial intelligence. Some are topping the charts. Nick Arter, a thirty-five-year-old in Washington, D.C., never quite managed to become a professional musician the old-fashioned way. He grew up in Harrisburg, Pennsylvania, in a music-loving family.
