Last week, Google unveiled its biggest change to search in years, showcasing new artificial intelligence capabilities that answer people’s questions in the company’s attempt to catch up to rivals Microsoft and OpenAI.The new technology has since generated a litany of untruths and errors — including recommending glue as part of a pizza recipe and the ingesting of rocks for nutrients — giving a black eye to Google and causing a furor online.The incorrect answers in the feature, called AI Overview, have undermined trust in a search engine that more than two billion people turn to for authoritative information. And while…

In 2021, David Sacks, a prominent venture capital investor and podcast host, said former President Donald J. Trump’s behavior around the Jan. 6 riot at the U.S. Capitol had disqualified him from being a future political candidate.At a tech conference last week, Mr. Sacks said his view had changed.“I have bigger disagreements with Biden than with Trump,” the investor said. Mr. Sacks said he and his podcast co-hosts were working on hosting a fund-raiser for Mr. Trump, which could include an interview for their “All In” show. They also extended an invitation to President Biden, he said, but the Trump…

One of the weirder, more unnerving things about today’s leading artificial intelligence systems is that nobody — not even the people who build them — really knows how the systems work.That’s because large language models, the type of A.I. systems that power ChatGPT and other popular chatbots, are not programmed line by line by human engineers, as conventional computer programs are.Instead, these systems essentially learn on their own, by ingesting vast amounts of data and identifying patterns and relationships in language, then using that knowledge to predict the next words in a sequence.One consequence of building A.I. systems this way…

As protests over the war in Gaza unfolded blocks away, last week’s Met Gala was largely devoid of political statements on the red carpet. That the organizers of fashion’s most powerful annual spectacle (one for which tickets cost $75,000 this year) achieved this feat proved surprising to many observers. Less than two weeks later, though, a fast-growing online protest movement is taking shape. At least, it is on TikTok, the social media platform that was a sponsor of the Met event.Blockout 2024, also referred to as Operation Blockout or Celebrity Block Party, targets high-profile figures who participants feel are not…

The two-story library has Oriental rugs, shaded lamps dotting its desks and rows of hardbacks lining its walls. It is the architectural centerpiece of the offices of OpenAI, the start-up whose online chatbot, ChatGPT, showed the world that machines can instantly generate their own poetry and prose.The building, which was once a mayonnaise factory, looks like a typical tech office, with its communal work spaces, well-stocked micro-kitchens and private nap rooms spread across three floors in San Francisco’s Mission District.But then there is that library, with the ambience of a Victorian Era reading room. Its shelves offer everything from Homer’s…

European Union regulators on Thursday opened investigations into the American tech giant Meta for the potentially addictive effects Instagram and Facebook have on children, an action with far-reaching implications because it cuts to the core of how the company’s products are designed.Meta’s products may “exploit the weaknesses and inexperience of minors” to create behavioral dependencies that threaten their mental well-being, the European Commission, the executive branch of the 27-member bloc, said in a statement. E.U. regulators could ultimately fine Meta up to 6 percent of its global revenue, which was $135 billion last year, as well as force other product…

Ilya Sutskever, the OpenAI co-founder and chief scientist who in November joined three other board members to force out Sam Altman, the company’s high-profile chief executive, before saying he regretted the move, is leaving the San Francisco A.I. company.Dr. Sutskever’s departure, which the company announced in a blog post on Tuesday, closes another chapter in a story that stunned Silicon Valley and that raised questions about whether Mr. Altman and his company were prepared to lead the tech industry into the age of artificial intelligence.After returning to OpenAI just five days after he was ousted, Mr. Altman reasserted his control…

When a children’s jewelry maker began advertising on Instagram, she promoted photos of a 5-year-old girl wearing a sparkly charm to users interested in parenting, children, ballet and other topics identified by Meta as appealing mostly to women.But when the merchant got the automated results of her ad campaign from Instagram, the opposite had happened: The ads had gone almost entirely to adult men.Perplexed and concerned, the merchant contacted The New York Times, which in recent years has published multiple articles about the abuse of children on social media platforms. In February, The Times investigated Instagram accounts run by parents…

Apple’s top software executives decided early last year that Siri, the company’s virtual assistant, needed a brain transplant.The decision came after the executives Craig Federighi and John Giannandrea spent weeks testing OpenAI’s new chatbot, ChatGPT. The product’s use of generative artificial intelligence, which can write poetry, create computer code and answer complex questions, made Siri look antiquated, said two people familiar with the company’s work, who didn’t have permission to speak publicly.Introduced in 2011 as the original virtual assistant in every iPhone, Siri had been limited for years to individual requests and had never been able to follow a conversation.…

Apple doesn’t make mistakes often and seldom apologizes, but on Thursday, its head of advertising said the company had erred in making a new iPad commercial that showed an industrial compressor flattening tools for art, music and creativity.“Creativity is in our DNA at Apple, and it’s incredibly important to us to design products that empower creatives all over the world,” said Tor Myhren, the company’s vice president of marketing communications, in a statement provided to the publication AdAge. “Our goal is to always celebrate the myriad of ways users express themselves and bring their ideas to life through iPad. We…
