    Physical Intelligence, a Specialist in Robot A.I., Raises $400 Million

    by

    The start-up raised $400 million in a funding round with investments from the likes of Jeff Bezos, Thrive Capital and OpenAI.Physical Intelligence, an artificial intelligence start-up seeking to create brains for a wide variety of robots, plans to announce on Monday that it had raised $400 million in financing from major investors.The round was led by Jeff Bezos, Amazon’s executive chairman, and the venture capital firms Thrive Capital and Lux Capital. Other investors include OpenAI, Redpoint Ventures and Bond.The fund-raising valued the company at about $2 billion, not including the new investments. That’s significantly more than the $70 million that the start-up, which was founded this year, had raised in seed financing.The company wants to make foundational software that would work for any robot, instead of the traditional approach of creating software for specific machines and specific tasks.“What we’re doing is not just a brain for any particular robot,” said Karol Hausman, the company’s co-founder and chief executive. “It’s a single generalist brain that can control any robot.”It’s a tricky task: Building such a model requires a huge amount of data on how to operate in the real world. Those information sets largely do not exist, compelling the company to compile its own. Its work has been aided by big leaps in A.I. models that can interpret visual data.Among the company’s co-founders are Mr. Hausman, a former robotics scientist at Google; Sergey Levine, a professor at the University of California, Berkeley; and Lachy Groom, an investor and former executive at the payments giant Stripe.In a paper published last week, Physical Intelligence showed how its software — called π0, or pi-zero — enabled robots to fold laundry, clear a table, flatten a box and more.“It’s a true generalist,” Mr. Hausman said. Physical Intelligence executives said that its software was closer to GPT-1, the first model published for chatbots by OpenAI, than to the more advanced brains that power ChatGPT.Mr. Groom said that it was hard to predict the rate of progress: A ChatGPT-style breakthrough “could be far sooner than we expect, or it could definitely be far out.”The field of robotics A.I. is getting crowded, with players including Skild, which is also working on general-purpose robot A.I.; Figure AI, whose backers include OpenAI and Mr. Bezos; and Covariant, which focuses on industrial applications.Amazon has a vested interest in the industry, and has been adding more robots in its operations as it seeks to drive down costs and get orders to customers faster. Tesla also has major A.I. ambitions, with Elon Musk recently saying that the company’s humanoid robot would be “the biggest product ever of any kind.” More

      Microsoft and OpenAI’s Close Partnership Shows Signs of Fraying

      by

      The “best bromance in tech” has had a reality check as OpenAI has tried to change its deal with Microsoft and the software maker has tried to hedge its bet on the start-up.Last fall, Sam Altman, OpenAI’s chief executive, asked his counterpart at Microsoft, Satya Nadella, if the tech giant would invest billions of dollars in the start-up.Microsoft had already pumped $13 billion into OpenAI, and Mr. Nadella was initially willing to keep the cash spigot flowing. But after OpenAI’s board of directors briefly ousted Mr. Altman last November, Mr. Nadella and Microsoft reconsidered, according to four people familiar with the talks who spoke on the condition of anonymity.Over the next few months, Microsoft wouldn’t budge as OpenAI, which expects to lose $5 billion this year, continued to ask for more money and more computing power to build and run its A.I. systems.Mr. Altman once called OpenAI’s partnership with Microsoft “the best bromance in tech,” but ties between the companies have started to fray. Financial pressure on OpenAI, concern about its stability and disagreements between employees of the two companies have strained their five-year partnership, according to interviews with 19 people familiar with the relationship between the companies.That tension demonstrates a key challenge for A.I. start-ups: They are dependent on the world’s tech giants for money and computing power because those big companies control the massive cloud computing systems the small outfits need to develop A.I.No pairing displays this dynamic better than Microsoft and OpenAI, the maker of the ChatGPT chatbot. When OpenAI got its giant investment from Microsoft, it agreed to an exclusive deal to buy computing power from Microsoft and work closely with the tech giant on new A.I.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Can Math Help AI Chatbots Stop Making Stuff Up?

      by

      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.

      Will A.I. Be a Bust? A Wall Street Skeptic Rings the Alarm.

      by

      Jim Covello, Goldman Sachs’s head of stock research, warned that building too much of what the world doesn’t need “typically ends badly.”As Jim Covello’s car barreled up highway 101 from San Jose to San Francisco this month, he counted the billboards about artificial intelligence. The nearly 40 signs he passed, including one that promoted something called Writer Enterprise AI and another for Speech AI, were fresh evidence, he thought, of an economic bubble.“Not that long ago, they were all crypto,” Mr. Covello said of the billboards. “And now they’re all A.I.”Mr. Covello, the head of stock research at Goldman Sachs, has become Wall Street’s leading A.I. skeptic. Three months ago, he jolted markets with a research paper that challenged whether businesses would see a sufficient return on what by some estimates could be $1 trillion in A.I. spending in the coming years. He said that generative artificial intelligence, which can summarize text and write software code, makes so many mistakes that it was questionable whether it would ever reliably solve complex problems.The Goldman paper landed days after a partner at Sequoia Capital, a venture firm, raised similar questions in a blog post about A.I. Their skepticism marked a turning point for A.I.-related stocks, leading to a reassessment of Wall Street’s hottest trade.Goldman’s basket of A.I. stocks, which is managed by a separate arm of the firm and includes Nvidia, Microsoft, Apple, Alphabet, Amazon, Meta and Oracle, has declined 7 percent from its peak on July 10, as investors and business leaders debate whether A.I. can justify its staggering costs.The pause has come early in the A.I. arms race. The tech industry has a history of spending big to deliver technology transitions, as it did during the personal computer and internet revolutions. Those build outs spanned five years or more before there was a reckoning.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      OpenAI Names Political Veteran Chris Lehane as Head of Global Policy

      by

      The prominent A.I. start-up is also considering a change to its corporate structure to make it more appealing to outside investors.Amid a flurry of news around its funding plans, OpenAI has tapped the political veteran Chris Lehane as its vice president of global policy.Mr. Lehane held a similar role at Airbnb and served in the Clinton White House as a lawyer and spokesman who specialized in opposition research. He earned a reputation as “the master of disaster” during his time working for President Bill Clinton.As OpenAI has built increasingly powerful artificial intelligence technologies, it has warned of their potential danger, and it is under pressure from lawmakers, regulators and others across the globe to ensure that these technologies do not cause serious harm. Some researchers worry that the A.I. systems could be used to spread disinformation, fuel cyberattacks or even destroy humanity.Mr. Lehane could help navigate an increasingly complex social and political landscape. Through a spokeswoman, he declined to comment.A spokeswoman for OpenAI, Liz Bourgeois, said, “Just as the company is making changes in other areas of the business to scale the impact of various teams as we enter this next chapter, we recently made changes to our global affairs organization.”OpenAI is negotiating a new funding deal that would value the company at more than $100 billion, three people familiar with discussions have said. The deal would be led by the investment firm Thrive Capital, which would invest more than $1 billion.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Meta in Talks to Use Voices of Judi Dench, Awkwafina and Others for A.I.

      by

      If deals are struck, Meta may incorporate the actors’ voices into a digital assistant product called MetaAI, people with knowledge of the effort said.Meta is in discussions with Awkwafina, Judi Dench and other actors and influencers for the right to incorporate their voices into a digital assistant product called MetaAI, according to three people with knowledge of the talks, as the company pushes to build more products that feature artificial intelligence.Apart from Ms. Dench and Awkwafina, Meta is in talks with the comedian Keegan-Michael Key and other celebrities, said the people, who spoke on the condition of anonymity because the discussions are private. They added that all of Hollywood’s top talent agencies were involved in negotiations with the tech giant.The talks remain fluid, and it is unclear which actors and influencers, if any, may sign on to the project, the people said. If the parties come to an agreement, Meta could pay millions of dollars in fees to the actors.A Meta spokesman declined to comment. The discussions were reported earlier by Bloomberg.Meta, which owns Facebook, Instagram and WhatsApp, has invested heavily in artificial intelligence, which the biggest tech companies are racing to develop and lead. Meta has plowed billions into weaving the technology into its social networking apps and advertising business, including by creating artificially intelligent characters that could chat through text across its messaging apps.On Wednesday, Mark Zuckerberg, Meta’s chief executive, increased how much his company would spend on A.I. and other expenses this year to at least $37 billion, up from $30 billion at the beginning of 2024. Mr. Zuckerberg said he would rather build too fast “rather than too late” to prevent his competitors from gaining an edge in the A.I. race.One area of A.I. that is rapidly emerging are chatbots with voice abilities, which act as virtual assistants. In May, OpenAI, a leading A.I. company, unveiled a version of its ChatGPT chatbot that could receive and respond to voice commands, images and videos. It was part of a wider effort to combine conversational chatbots with voice assistants like the Google Assistant and Apple’s Siri.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Hey, Siri! Let’s Talk About How Apple Is Giving You an A.I. Makeover.

      by

      Apple, a latecomer to artificial intelligence, has struck a deal with OpenAI and developed tools to improve its Siri voice assistant, which it is set to showcase on Monday.Each June, Apple unveils its newest software features for the iPhone at its futuristic Silicon Valley campus. But at its annual developer conference on Monday, the company will shine a spotlight on a feature that isn’t new: Siri, its talking assistant, which has been around for more than a decade.What will be different this time is the technology powering Siri: generative artificial intelligence.In recent months, Adrian Perica, Apple’s vice president of corporate development, has helped spearhead an effort to bring generative A.I. to the masses, said two people with knowledge of the work, who asked for anonymity because of the sensitivity of the effort.Mr. Perica and his colleagues have talked with leading A.I. companies, including Google and OpenAI, seeking a partner to help Apple deliver generative A.I. across its business. Apple recently struck a deal with OpenAI, which makes the ChatGPT chatbot, to fold its technology into the iPhone, two people familiar with the agreement said. It was still in talks with Google as of last week, two people familiar with the conversations said.That has helped lead to a more conversational and versatile version of Siri, which will be shown on Monday, three people familiar with the company said. Siri will be powered by a generative A.I. system developed by Apple, which will allow the talking assistant to chat rather than just respond to one question at a time. Apple will market its new A.I. capabilities as Apple Intelligence, a person familiar with the marketing plan said.Apple, OpenAI and Google declined to comment. Apple’s agreement with OpenAI was previously reported by The Information and Bloomberg, which also reported the name for Apple’s A.I. system.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      A.I.’s Black Boxes Just Got a Little Less Mysterious

      by

      Researchers at the A.I. company Anthropic claim to have found clues about the inner workings of large language models, possibly helping to prevent their misuse and to curb their potential threats.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 massive 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 is that it’s difficult to reverse-engineer them or to fix problems by identifying specific bugs in the code. Right now, if a user types “Which American city has the best food?” and a chatbot responds with “Tokyo,” there’s no real way of understanding why the model made that error, or why the next person who asks may receive a different answer.And when large language models do misbehave or go off the rails, nobody can really explain why. (I encountered this problem last year, when a Bing chatbot acted in an unhinged way during an interaction with me, and not even top executives at Microsoft could tell me with any certainty what had gone wrong.)The inscrutability of large language models is not just an annoyance but a major reason some researchers fear that powerful A.I. systems could eventually become a threat to humanity.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Scarlett Johansson Said No, but OpenAI’s Virtual Assistant Sounds Just Like Her

      by

      Last week, the company released a chatbot with an option that sounded like the actress, who provided the voice of an A.I. system in the movie “Her.”Days before OpenAI demonstrated its new, flirty voice assistant last week, the actress Scarlett Johansson said, Sam Altman, the company’s chief executive, called her agent and asked that she consider licensing her voice for a virtual assistant.It was his second request to the actress in the past year, Ms. Johannson said in a statement on Monday, adding that the reply both times was no.Despite those refusals, Ms. Johansson said, OpenAI used a voice that sounded “eerily similar to mine.” She has hired a lawyer and asked OpenAI to stop using a voice it called “Sky.”OpenAI suspended its release of “Sky” over the weekend. The company said in a blog post on Sunday that “AI voices should not deliberately mimic a celebrity’s distinctive voice — Sky’s voice is not an imitation of Scarlett Johansson but belongs to a different professional actress using her own natural speaking voice.”For Ms. Johansson, the episode has been a surreal case of life-imitating art. In 2013, she provided the voice for an A.I. system in the Spike Jonze movie “Her.” The film told the story of a lonely introvert seduced by a virtual assistant named Samantha, a tragic commentary on the potential pitfalls of technology as it becomes more realistic.Last week, Mr. Altman appeared to nod to the similarity between OpenAI’s virtual assistant and the film in a post on X with the single word “her.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
