Chatbots like ChatGPT get stuff wrong. But researchers are building new A.I. systems that can verify their own math — and maybe more.On a recent afternoon, Tudor Achim gave a brain teaser to an A.I. bot called Aristotle.The question involved a 10-by-10 table filled with a hundred numbers. If you collected the smallest number in each row and the largest number in each column, he asked, could the largest of the small numbers ever be greater than the smallest of the large numbers?The bot correctly answered “No.” But that was not surprising. Popular chatbots like ChatGPT may give the right answer, too. The difference was that Aristotle had proven that its answer was right. The bot generated a detailed computer program that verified “No” was the correct response.Chatbots like ChatGPT from OpenAI and Gemini from Google can answer questions, write poetry, summarize news articles and generate images. But they also make mistakes that defy common sense. Sometimes, they make stuff up — a phenomenon called hallucination.Mr. Achim, the chief executive and co-founder of a Silicon Valley start-up called Harmonic, is part of growing effort to build a new kind of A.I. that never hallucinates. Today, this technology is focused on mathematics. But many leading researchers believe they can extend the same techniques into computer programming and other areas.Because math is a rigid discipline with formal ways of proving whether an answer is right or wrong, companies like Harmonic can build A.I. technologies that check their own answers and learn to produce reliable information.Google DeepMind, the tech giant’s central A.I. lab, recently unveiled a system called AlphaProof that operates in this way. Competing in the International Mathematical Olympiad, the premier math competition for high schoolers, the system achieved “silver medal” performance, solving four of the competition’s six problems. It was the first time a machine had reached that level.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Karen Dunn, who is preparing the vice president for next week’s clash, has trained Democrats for debates in every election since 2008. Her approach, as Hillary Clinton put it, is “tough love.”Vice President Kamala Harris has never met or spoken with former President Donald J. Trump, but the woman running her debate preparations has spent a lot of time thinking about how to respond to what Republican nominees say during an onstage clash.That outside Harris adviser, Karen L. Dunn, a high-powered Washington lawyer, has trained Democratic presidential and vice-presidential candidates for debates in every election since 2008.She is described by candidates she has coached and other people who have worked with her as a skilled handler of high-ego politicians. By all accounts, she possesses the rare ability to tell them what they are doing wrong and how to fix it — and how to inject humor and humanity to sell themselves to voters watching the debate.“It’s a combination of tough love,” Hillary Clinton, whom Ms. Dunn helped prepare for presidential debates in 2008 and 2016, said in an interview on Thursday. “She’s unafraid to say, ‘That’s not going to work’ or ‘That doesn’t make sense’ or ‘You can do better.’ But she also offers encouragement, like, ‘Look, I think you’re on the right track here’ and ‘You just need to do more of that.’”The emergence of Ms. Dunn as the leader of Ms. Harris’s debate team comes at a critical moment in both the presidential race and Ms. Dunn’s professional life.When she is not preparing top Democrats for debates — in addition to her four previous cycles of involvement at the presidential and vice-presidential level, she has worked with Senators Mark Warner of Virginia and Cory Booker of New Jersey — Ms. Dunn is a top lawyer for some of America’s leading technology firms.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

The agreement includes $70 million from the state, which needs legislative approval. Some lawmakers objected, calling for a more comprehensive solution with tech companies.Google, a news industry trade group and key California lawmakers announced a first-in-the-nation agreement on Wednesday aimed at shoring up newsrooms in the state with as much as $250 million.Through a mix of funding from Google, taxpayers and potentially other private sources, the five-year deal would let Google avert a proposed state bill that could force tech companies to pay news organizations when advertising appeared alongside articles on the tech company’s platform.The announcement was packed with praise for the effort to stabilize the news industry, which has faced layoffs and shuttered newsrooms as readership has shifted online.“The deal not only provides funding to support hundreds of new journalists but helps rebuild a robust and dynamic California press corps for years to come, reinforcing the vital role of journalism in our democracy,” Gov. Gavin Newsom said in a statement.The trade group, the California News Publishers Association, called the agreement “a first step toward what we hope will become a comprehensive program to sustain local news in the long term.” The author of the bill, Assemblymember Buffy Wicks, praised it for being a “cross-sector commitment” and called it “just the beginning.”A union representing journalists, however, denounced the deal as a “shakedown,” and lawmakers who had been working for months on more comprehensive proposals criticized its scope. Also, the president pro tempore of the State Senate, Mike McGuire, questioned legislative support for the state’s share of the deal, which would require approval as part of the annual budget process.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Google, Microsoft and Amazon have made deals with A.I. start-ups for their technology and top employees, but have shied from owning the firms. Here’s why.In 2022, Noam Shazeer and Daniel De Freitas left their jobs developing artificial intelligence at Google. They said the tech giant moved too slowly. So they created Character.AI, a chatbot start-up, and raised nearly $200 million.Last week, Mr. Shazeer and Mr. De Freitas announced that they were returning to Google. They had struck a deal to rejoin its A.I. research arm, along with roughly 20 percent of Character.AI’s employees, and provide their start-up’s technology, they said.But even though Google was getting all that, it was not buying Character.AI.Instead, Google agreed to pay $3 billion to license the technology, two people with knowledge of the deal said. About $2.5 billion of that sum will then be used to buy out Character.AI’s shareholders, including Mr. Shazeer, who owns 30 percent to 40 percent of the company and stands to net $750 million to $1 billion, the people said. What remains of Character.AI will continue operating without its founders and investors.The deal was one of several unusual transactions that have recently emerged in Silicon Valley. While big tech companies typically buy start-ups outright, they have turned to a more complicated deal structure for young A.I. companies. It involves licensing the technology and hiring the top employees — effectively swallowing the start-up and its main assets — without becoming the owner of the firm.These transactions are being driven by the big tech companies’ desire to sidestep regulatory scrutiny while trying to get ahead in A.I., said three people who have been involved in such agreements. Google, Amazon, Meta, Apple and Microsoft are under a magnifying glass from agencies like the Federal Trade Commission over whether they are squashing competition, including by buying start-ups.“Large tech firms may clearly be trying to avoid regulatory scrutiny by not directly acquiring the targeted firms,” said Justin Johnson, a business economist who focuses on antitrust at Cornell University. But “these deals do indeed start to look a lot like regular acquisitions.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Elon Musk, the world’s richest man, has waded into one of the thorniest issues facing U.S. politics: deepfake videos.On Friday night, Mr. Musk, the billionaire owner of the social media platform X, reposted an edited campaign video for Vice President Kamala Harris that appears to have been digitally manipulated to change the spot’s voice-over in a deceptive manner.The video mimics Ms. Harris’s voice, but instead of using her words from the original ad, it has the vice president saying that President Biden is senile, that she does not “know the first thing about running the country” and that, as a woman and a person of color, she is the “ultimate diversity hire.”In addition, the clip was edited to remove images of former President Donald J. Trump and his running mate, Senator JD Vance of Ohio, and to add images of Mr. Biden. The original, unaltered ad, which the Harris campaign released on Thursday, is titled “We Choose Freedom.”The version posted on X does not contain a disclaimer, though the account that first uploaded it Friday morning, @MrReaganUSA, noted in its post that the video was a “parody.” When Mr. Musk reposted the video on his own account eight hours later, he made no such disclosure, stating only, “This is amazing,” followed by a laughing emoji.Mr. Musk’s post, which has since been viewed 98 million times, would seem to run afoul of X’s policies, which prohibit sharing “synthetic, manipulated or out-of-context media that may deceive or confuse people and lead to harm.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

The search giant’s negotiations to buy Wiz, a cybersecurity start-up, for $23 billion, come as the Biden administration has taken a hard line against consolidation in tech and other industries.Google, which became one of the world’s the most valuable companies through its search engine and other consumer internet services, is nearing its largest-ever acquisition to improve what it can offer to business customers.Google is in talks to buy Wiz, a New York-based cybersecurity start-up, according to three people with knowledge of the discussions, who were not authorized to discuss them. Wiz was last valued at $12 billion.The companies have valued the deal at roughly $23 billion, said one of the people, easily making it Google’s most expensive acquisition and nearly double what the company paid for Motorola Mobility in 2012.While a deal looks likely, talks could still fall apart, the people said.Google and Wiz did not respond to requests for comment. The Wall Street Journal earlier reported that the companies were discussing a deal.Google has moved forward with negotiations despite the possibility that regulators might try to block the deal. But the company may be willing to fight to beef up its cloud-computing division, which lags behind Amazon Web Services and Microsoft Azure.Google was sued by the Justice Department in two separate antitrust cases, one targeting its ubiquitous search engine and another seeking to break up its digital advertising-technology business. A verdict in the search case is expected this summer.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Ordering mistakes frustrated customers during nearly three years of tests. But competitors like White Castle and Wendy’s say their A.I. ordering systems have been highly accurate.In the nearly three years since McDonald’s announced that it was partnering with IBM to develop a drive-through order taker powered by artificial intelligence, videos popped up on social media showing confused and frustrated customers trying to correct comically inaccurate meals.“Stop! Stop! Stop!” two friends screamed with humorous anguish on a TikTok video as an A.I. drive-through misunderstands their order, tallying up 240, 250 and then 260 Chicken McNuggets.In other videos, the A.I. rings up a customer for nine iced teas instead of one, fails to explain why a customer could not order Mountain Dew and thought another wanted to add bacon to his ice cream.So when McDonald’s announced in a June 13 internal email, obtained by the trade publication Restaurant Business, that it was ending its partnership with IBM and shutting down its A.I. tests at more than 100 U.S. drive-throughs, customers who had interacted with the service were probably not shocked.The decision to abandon the IBM deal comes as many other businesses, including its competitors, are investing in A.I. But it exemplifies some of the challenges companies are facing as they jockey to unlock the revolutionary technology’s potential.Other fast-food companies have had success with A.I. ordering. Last year, Wendy’s formed a partnership with Google Cloud to build out its A.I. drive-through system. Carl’s Jr. and Taco John’s have hired Presto, a voice A.I. firm for restaurants. Panda Express has approximately 30 automated order takers at its windows through a partnership with the voice A.I. firm SoundHound AI.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
