Elon Musk is suing Microsoft-backed OpenAI and its CEO, Sam Altman, among others, alleging they abandoned the company’s founding mission to develop artificial intelligence “for the benefit of humanity broadly.”

In a lawsuit filed Thursday with a San Francisco court, Musk’s lawyers said the tech billionaire was approached in 2015 by Altman and OpenAI co-founder Greg Brockman and agreed to form a nonprofit lab that would develop artificial general intelligence for the “benefit of humanity.”

A co-founder of OpenAI in 2015, Musk stepped down from the firm’s board in 2018, four years after saying that AI is “potentially more dangerous than nukes.”

“To this day, OpenAI, Inc.’s website continues to profess that its charter is to ensure that AGI benefits all of humanity.’ In reality, however, OpenAI, Inc. has been transformed into a closed-source de facto subsidiary of the largest technology company in the world: Microsoft,” the lawsuit filing said.

Musk’s lawyers said in the lawsuit that OpenAI’s focus on maximizing profits for Microsoft breaks that agreement.

“Under its new Board, it is not just developing but is actually refining an AGI to maximize profits for Microsoft, rather than for the benefit of humanity,” the filing said.

OpenAI and Microsoft were not immediately available for comment.

Musk’s lawyers said the suit was submitted “to compel OpenAI to adhere to the Founding Agreement and return to its mission to develop AGI for the benefit of humanity, not to personally benefit the individual Defendants and the largest technology company in the world.”

Microsoft, which is facing scrutiny from EU antitrust regulators over its reported $13 billion investment in OpenAI, recently announced a new partnership with French start-up Mistral AI.

The U.S. tech giant said on Monday that it was investing in the company, which is regarded as Europe’s answer to OpenAI, to help it unlock “new commercial opportunities” and expand to global markets.

The legal action pits two of the world’s most prominent tech leaders against each other at a time of extraordinary hype over the future of AI.

Since debuting in November 2022, OpenAI’s chatbot, ChatGPT, has taken the world by storm. The AI tool quickly became the fastest-growing consumer application in history and kick-started the launch of rival chatbots from companies such as Google parent Alphabet and Microsoft.

Both Musk and Altman have been making headlines. Musk, considered the world’s richest person, runs electrical vehicle maker Tesla, rocket and satellite maker SpaceX, and bought X for $44 billion in October 2022. He recently reported the advances of the brain chip technology implants produced by his startup Neuralink.

Altman has meanwhile had a rocky relationship with OpenAI. He was suddenly fired from the company in November of last year, in a move that sent shock waves across the tech industry. The American entrepreneur — one of the leading figures in the AI boom — returned to the firm a few days later.

Nvidia shares jumped more than 14% in premarket trade on Thursday after the chip giant posted bumper earnings that beat Wall Street estimates.

The U.S. tech giant posted revenue of $22.10 billion for its fiscal fourth quarter, a rise of 265% year-on-year, while net income surged by 769%, as the company continues to see a boost from excitement over artificial intelligence.

Nvidia chips are used to train the huge AI models such as those developed by Microsoft and Meta.

Nvidia sees no signs of slowing. The company forecast its revenue in the current quarter will hit $24 billion, way ahead of estimates.

“Fundamentally, the conditions are excellent for continued growth” in 2025 and beyond, Nvidia CEO Jensen Huang told analysts on Wednesday, adding to the bullish sentiment around the stock.

Nvidia’s Data Center business, which includes the company’s H100 graphics cards that are used for AI training, posted sales of $18.4 billion in the fourth quarter, representing 409% year-on-year growth.

The positive outlook from Nvidia prompted a round of broker upgrades on Thursday. JPMorgan raised its price target on Nvidia’s stock from $650 to $850, while Bank of America Global Research hiked its target from $800 to $925.

Nvidia’s stock closed at $674.72 on Thursday. Shares were under pressure ahead of the earnings report as traders took profit and investors were concerned that Nvidia might not be able to hit lofty expectations.

But its market-beating numbers dispelled those fears and also pulled other global chip stocks higher.

Microsoft said in a Friday regulatory filing that a Russian intelligence group accessed some of the software maker’s top executives’ email accounts. Nobelium, the same group that breached government supplier SolarWinds in 2020, carried out the attack, which Microsoft detected last week, according to the company.

It isn’t the first time Russian hackers have gained entry into Microsoft’s systems. State-sponsored attacks that can result in the dissemination of sensitive data becomes a greater risk during periods of armed conflict, and Russia’s war against Ukraine has been going on for almost two years now. On Thursday, Russia said Ukrainian forces conducted drone strikes in multiple Russian locations.

Microsoft’s announcement comes after new U.S. requirements for disclosing cybersecurity incidents went into effect. A Microsoft spokesperson said that while the company does not believe the attack had a material effect, it still wanted to honor the spirit of the rules.

The Cybersecurity and Infrastructure Security Agency is “closely coordinating with Microsoft to gain additional insights into this incident and understand impacts so we can help protect other potential victims,” CISA executive assistant director for cybersecurity Eric Goldstein said in a statement to CNBC. “As noted in Microsoft’s announcement, at this time we are not aware of impacts to Microsoft customer environments or products.” 

In late November, the group accessed “a legacy non-production test tenant account,” Microsoft’s Security Response Center wrote in the blog post. After gaining access, the group “then used the account’s permissions to access a very small percentage of Microsoft corporate email accounts, including members of our senior leadership team and employees in our cybersecurity, legal, and other functions, and exfiltrated some emails and attached documents,” the corporate unit wrote.

The company’s senior leadership team, including Chief Financial Offer Amy Hood and President Brad Smith, regularly meets with CEO Satya Nadella.

Microsoft said it has not found signs that Nobelium had accessed customer data, production systems or proprietary source code.

The U.S. government and Microsoft consider Nobelium to be part of the Russian foreign intelligence service SVR. The hacking group was responsible for one of the most prolific breaches in U.S. history when it added malicious code to updates to SolarWinds’ Orion software, which some U.S. government agencies were using. Microsoft itself was ensnared in the hack.

Nobelium, also known as APT29 or Cozy Bear, is a sophisticated hacking group that has attempted to breach the systems of U.S. allies and the Department of Defense. Microsoft also uses the name Midnight Blizzard to identify Nobelium.

It was also implicated alongside another Russian hacking group in the 2016 breach of the Democratic National Committee’s systems.

Last year, a vulnerability in Microsoft software allowed China-aligned hackers to access the email accounts of senior government officials, including Commerce Secretary Gina Raimondo, ahead of a critical U.S.-China meeting. The company’s “negligent cybersecurity practices” led to the attack, Sen. Ron Wyden, a Democrat from Oregon, wrote in a letter to CISA director Jen Easterly, and other federal officials.

“We are continuing our investigation and will take additional actions based on the outcomes of this investigation and will continue working with law enforcement and appropriate regulators,” the Microsoft blog post said.

The Federal Bureau of Investigation told CNBC that it knows about the attack and is working with federal partners to help.

In November, CNBC visited Apple’s campus in Cupertino, California, to get a look inside one of the company’s many chip labs. CNBC also got a rare chance to talk with the senior vice president of hardware technologies, Johny Srouji, and Apple’s senior vice president of hardware engineering, John Ternus, about the company’s push into the complex business of custom semiconductor development, which is also being pursued by Amazon, Google, Microsoft and Tesla.

Unlike traditional chipmakers such as Nvidia and Intel, Apple is not making silicon for other companies.

“Because we’re not really selling chips outside, we focus on the product,” Johny Srouji said. “That gives us freedom to optimize, and the scalable architecture lets us reuse pieces between different products.”

Watch the full interview to hear the executives speak about AI, its latest A17 Pro chip, working with manufacturing partner Taiwan Semiconductor Manufacturing Company and more.

Microsoft-owned Activision Blizzard has agreed to settle a case from a California state agency that alleged the video game publisher discriminated against women, including denying them promotion opportunities and paying them less.

California’s Civil Rights Department said in a statement on Friday that as part of a proposed settlement agreement, Activision Blizzard will pay nearly $55 million to provide relief to female employees and contractors from October 2015 to December 2020 and cover legal fees. About $46 million of the total will go to the fund for affected women, the agency said in the statement.

The news comes almost two years after Activision Blizzard settled a case from the U.S. Equal Employment Opportunity Commission, which pointed to sexual harassment, pregnancy discrimination and retaliation. As a result, the company agreed to form an $18 million fund to pay victims.

In 2021, the agency, then known as the Department of Fair Employment and Housing, filed a suit against the company, presenting allegations of sexual harassment, discrimination and retaliation. Months later, the Wall Street Journal reported that while Activision Blizzard CEO Bobby Kotick was aware of allegations of misconduct inside the company, he didn’t share all relevant information with its board.

Shares fell, and Microsoft subsequently began talks to acquire Activision Blizzard, the maker of Call of Duty.

The $69 billion deal closed in October after regulators in the U.S. and Europe looked carefully at it. The Federal Trade Commission argued in San Francisco appellate court last week that a federal judge made mistakes in rejecting the regulatory agency’s attempt to stop the companies from completing the transaction.

The Los Angeles County Superior Court must approve Activision’s settlement with the state agency, according to the statement. The agency will file a new complaint that excludes prior harassment allegations, according to the proposed settlement agreement, which CNBC viewed.

The agreement would require Activision to keep up efforts around inclusion of underrepresented people in recruiting. Except when compensation is non-negotiable, the company would have to tell job applicants in writing at the start of hiring and promotion processes that they can negotiate their pay.

“We appreciate the importance of the issues addressed in this agreement and we are dedicated to fully implementing all the new obligations we have assumed as part of it,” Activision said in a statement to CNBC.

Training of elite athletes dates as far back as the Ancient Olympic Games, when so-called gymnastes advised runners, chariot racers, wrestlers and boxers on technique, nutrition and strength conditioning.

Fast forward to today’s Olympians prepping for next summer’s Paris Games. Their trainers and coaches adhere to the same Olympic motto — faster, higher, stronger — yet have the added benefit of millennia of ever-advancing technology, which now has been super-charged with artificial intelligence.

Trainers and coaches at U.S. Soccer, one of the 47 National Governing Bodies overseen by the United States Olympic and Paralympic Committee, are using AI technology to instantaneously identify and track player movements and ball positions. A suite of software tools allows them to study a variety of human performance metrics, such as body position, velocity, speed and timing in real time on the field of play.

“Utilizing advances in AI and computer vision, we’ve been able to track and study personalized analytics from a variety of sports to determine the strengths and deficiencies in an athlete’s movement and help them make data-informed training and competition plans that can help them improve their performance, as well as their own health,” said Mike Levine, director of performance innovation business operations at the USOPC, based in Colorado Springs, also the home of a high-tech Olympic training center.

While the USOPC and NGBs employ in-house experts in bleeding-edge technology development, data analytics and sports sciences and medicine, big tech companies lend their AI know-how as well. USA Surfing staff, for instance, has teamed up with Microsoft engineers to figure out how best to ride waves. They take digital videos of surfers in action and use AI to analyze data on body movement, surfboards and waves to determine what they did well and what could be improved.

“This work saves coaches and staff hundreds of hours of video tagging, facilitates the accumulation of more and higher-quality data and affords analysts and coaches significantly more time to analyze the data and implement learnings into real-life training and performance,” Levine said.

Creating 3-D models of athletes’ bodies with Intel technology

These are manifestations of computer vision systems, which use AI technology to replicate the capabilities of the human brain responsible for object recognition and classification. A commercial application, called 3D Athlete Tracking (3DAT), was developed by Intel‘s Olympic Technology Group a few years ago and is now being utilized by trainers in numerous sports. 3DAT incorporates sensor-less motion capture and digital video to create three-dimensional models of an athlete’s entire body, from head to toes, which trainers use to tweak and improve performance.

“We’re able to see ways athletes move and detect things not possible with just the human eye,” said Jonathan Lee, who as senior director of sports technology at Intel helped develop 3DAT and is now chief product officer at London-based sports tech company ai.io, which recently acquired the system from Intel.

3DAT has been adopted by Exos, a coaching company in Scottsdale, Arizona, that trains college football players for the National Football League’s annual scouting combine, an evaluation ahead of the league’s yearly draft. “Exos uses 3DAT to analyze the 40-yard dash and help players get faster,” Lee said. Digital video cameras, mounted on timing gates incrementally positioned along the course, capture data on how a runner comes off the line, his acceleration and velocity, and his body’s angle of attack.

The data instantaneously constructs a personalized skeletal model of each player for immediate review. Before a player’s next sprint, a trainer might say, “You need to be more upright or lean forward, and give him tips on how to achieve that,” Lee said.

The NFL-Amazon digital player and concussion-risk tracking

The NFL itself is harnessing AI and computer vision to enhance its Digital Athlete program, developed in partnership with Amazon Web Services beginning in 2019. The Digital Athlete provides a complete view of each NFL players’ experience by analyzing data from his training and game activity, which is captured by sensors and tags in equipment and hours of video from cameras in stadiums. Computer vision and machine learning systems track speed, collisions, blocks and tackles. This data is shared with clubs and allows teams to precisely understand what players need to stay healthy, recover quickly and perform at their best.

“AI and machine learning are the backbone of the program,” said Jennifer Langton, NFL senior vice president of health and safety innovation. “We’re able to analyze a substantial amount of data and automatically generate insights into which players might benefit from altering either training or recovery routines, a process that used to be so manual and cumbersome.”

The AI was taught to identify trauma by repeated exposure to and digestion of digital video images of helmets from all angles, Langton said, and then to cross-reference visual information from statistical data to determine what player was wearing what helmet. “With enough practice, the AI becomes exponentially faster and more reliable than humans at accurately identifying and classifying head collisions throughout a game and the season,” she said, allowing trainers and coaches to see which players are due to reduce their workloads and which have room for a more intensive workout.

The Digital Athlete program was rolled out as a pilot with four NFL teams last year and this season is available to all 32 franchises via a dedicated online portal. “The portal provides teams with a daily training load and risk-mitigation information, as well as league-wide injury trends and benchmarks they hadn’t had before,” Langton said, adding that the NFL will assess the data at the end of the season to evaluate tangible results of the program.

‘The next big thing’: Twin hearts of elite athletes

Another AI-enabled technology that’s making its way into elite athlete training is the digital twin, a virtual replica of a physical object, process or system that can be used to simulate, predict and improve real-world scenarios. Tata Consultancy Services, headquartered in Mumbai, recently announced a partnership with French tech developer Dassault Systèmes to produce a digital twin heart, mimicking the flesh-and-blood one of Des Linden, a two-time Olympic marathoner and winner of the 2018 Boston Marathon (sponsored by TCS, along with the races in New York, Chicago and London).

Linden’s avatar organ — created using AI-analyzed data from CT scans and MRIs — can simulate her heart rate, blood flow and oxygen levels, providing instant feedback that can be interpreted to adjust her training and competition. “We want to understand what is a safe zone for Des’ trainer to put her through,” said Dr. Srinivasan Jayaraman, a principal scientist at TCS. Instead of having her run on a treadmill or outdoors, “We can run simulations using her digital twin heart to vary different cardiovascular parameters and fine-tune her training.”

Linden is no stranger to sports tech, from online message boards back in her high school days for remotely comparing times with other runners to today’s state-of-the-art running shoes that world-class marathoners have broken records wearing. “The digital twin heart is going to be the next big thing,” she said. “Being able to map out [my training] and see the gains and drawbacks ahead of time will allow me to work smarter, not harder.”

That’s what Linden, aided by her digital twin heart, will be doing to train for the 2024 Olympic marathon trials in February. Qualifying for her third Team USA slot “will be a tough task,” said the 40-year-old runner, “but I’ll take a crack at it.”

AI and sports training diets

Although there’s no news yet of a digital twin of the human digestive system, AI is involved in planning Olympic athletes’ diet and nutrition. Alicia Glass, a senior sports dietician for the USOPC, designs meal plans for about 300 athletes with USA Track and Field and USA Swimming, a labor-intensive, hand-written task that’s been simplified with an AI-powered app called Notemeal. “They collected data from 37 dieticians from professional sports teams and organizations and used those data sets to generate individualized meal plans,” she said. “The value-add is that it’s a network of sports dieticians working with the best of the best athletes in the world.”

Glass still relies on her professional skills to understand the events each athlete competes in, their training regimens and goals, as well as their genetics, lean body mass and metabolic rate. Even athletes who train and compete in the same events require totally individualized meal plans, she said. “Notemeal makes that process a lot easier,” she said.

The athletes access Notemeal with a smartphone app. “I hit a toggle on my phone, and they get a text saying a meal has been created for you,” Glass said, adding that the app also applies AI to design personalized shopping lists and recipes.

Glass won’t claim that high-tech dietary planning will win medals next summer in Paris, but “many athletes would admit it helps improve their lifestyle because they’re more aware” of their personal fueling needs.

Linden says there is no turning back from the increasing role of technology in the lives of elite athletes. “Let’s just personalize the heck out of training and make sure we’re getting the maximum gains without setbacks from overworking,” she said.

Former OpenAI CEO Sam Altman will be joining Microsoft to lead a new advanced AI research team, according to Microsoft CEO Satya Nadella.

Nadella said on social media platform X that Altman and former OpenAI President and Board Chair Greg Brockman, alongside other colleagues, will be joining Microsoft to lead a new advanced AI research team.

Tech giant Microsoft has invested billions of dollars in OpenAI and has a close technology partnership with the company.

“We look forward to moving quickly to provide them with the resources needed for their success,” Nadella said.

“We remain committed to our partnership with OpenAI and have confidence in our product roadmap, our ability to continue to innovate with everything we announced at Microsoft Ignite, and in continuing to support our customers and partners.”

Altman himself reshared Nadella’s post, adding a somewhat cryptic comment to it: “The mission continues.”

Altman had been leading the company since 2019. OpenAI’s board announced late Friday that it was removing Altman and replacing him on an interim basis with technology chief Mira Murati. The post said that Altman “was not consistently candid in his communications with the board.”

This did not dissuade a group of OpenAI investors, who were pushing to bring Altman back as CEO over the weekend.

Late Sunday night, OpenAI said it was bringing on board former Twitch CEO Emmett Shear to run the artificial intelligence company. Just hours after, Nadella announced that Altman and Brockman — who was removed from his role as chairman on Friday alongside Altman, and later quit the company altogether — would be absorbed in-house into the Microsoft team.

Nadella said Sunday night he was looking forward to getting to know Shear and OpenAI’s new leadership team.

OpenAI, which was reportedly in talks as recently as last month to sell employee shares to investors at an $86 billion valuation, emerged as a household name this year after releasing its ChatGPT chatbot in late 2022. ChatGPT allows users to type in simple text queries and retrieve answers that can lead to more in-depth conversations.

— CNBC’s Ari Levy and Jordan Novet contributed to this report.

OpenAI investors are pushing to bring back Sam Altman as CEO one day after he was ousted by the board, according to people familiar with the matter.

Microsoft, Tiger Global and venture firm Thrive Capital are among several of OpenAI’s top backers that are part of an effort to reinstate Altman, said a source, who asked not to be named because discussions are confidential.

Sequoia Capital has also been in contact with Altman, a person familiar with knowledge of the matter told CNBC. Sequoia supports Altman and former OpenAI president Greg Brockman in whatever they choose to do next, whether it’s returning to OpenAI or creating a new startup, the person said. Sequoia also informed Microsoft that it would back efforts to bring back Altman and Brockman, the person said.

The Verge first reported on the talks to bring back Altman. The publication, citing a source, said Altman is “ambivalent” about returning and would demand governance changes. Altman didn’t immediately respond to CNBC’s request for comment. Nor did Thrive. Microsoft declined to comment.

OpenAI’s announcement late Friday that the company was firing Altman and replacing him on an interim basis with technology chief Mira Murati sent shockwaves across Silicon Valley. OpenAI has emerged as the hottest startup on the planet since launching its ChatGPT chatbot last year and spurring a rush of investment generative artificial intelligence market. The company had reportedly been in talks as recently as last month to sell employee shares at a valuation of $86 billion.

Microsoft, which has invested billions of dollars in OpenAI and has a close technology partnership with the company, was surprised by the announcement. In addition to ousting Altman, the company removed Brockman, the chairman, from his board leadership position but said he would remain as president. Brockman said later in the day that he quit.

WATCH: The OpenAI shakeup will not have a major impact on Microsoft, says analyst

OpenAI’s board of directors said Friday that Sam Altman will step down as CEO and will be replaced on an interim basis by technology chief Mira Murati.

The company said it conducted “a deliberative review process” and “concluded that he was not consistently candid in his communications with the board, hindering its ability to exercise its responsibilities.”

“The board no longer has confidence in his ability to continue leading OpenAI,” the statement said.

OpenAI’s board includes chief scientist Ilya Sutskever and independent directors such as Quora CEO Adam D’Angelo, technology entrepreneur Tasha McCauley, and Helen Toner of the Georgetown Center for Security and Emerging Technology. OpenAI says the board of its 501(c)(3) is the “overall governing body for all OpenAI activities.”

The board also said that Greg Brockman, OpenAI’s president, “will be stepping down as chairman of the board and will remain in his role at the company, reporting to the CEO.”

Sam Altman acknowledged that he was leaving OpenAI in a post on X on Friday, but did not mention any accusations by the firm’s board that he failed to be candid during unspecified reviews. He said he loved working at the company and that he would talk more about “what’s next later.”

Regarding the appointment of Murati, OpenAI said, “As the leader of the company’s research, product, and safety functions, Mira is exceptionally qualified to step into the role of interim CEO. We have the utmost confidence in her ability to lead OpenAI during this transition period.”

OpenAI, which has raised billions of dollars from Microsoft and ranked first on CNBC’s Disruptor 50 list this year, jumped into the mainstream in late 2022 after releasing its AI chatbot ChatGPT to the public. The service went viral by allowing users to convert simple text into creative conversation and has pushed big tech companies such as Alphabet and Meta to step up their investments in generative AI.

Microsoft shares slipped after the announcement, closing the day down 1.7% at $369.84.

A Microsoft spokesperson said in a statement that the company has “a long-term partnership with OpenAI and Microsoft remains committed to Mira and their team as we bring this next era of AI to our customers.”

In a post on X, Microsoft CEO Satya Nadella commented about his company’s “long-term agreement with OpenAI,” explaining that it would “remain committed to our partnership, and to Mira and the team.” Nadella did not address Altman’s departure.

Brockman also shared a post on X that included the message he sent to his former OpenAI colleagues, informing them that he “quit” after he learned about “today’s news.”

Later in the evening, Brockman said in an X post that both he and Altman were “shocked and saddened by what the board did today.”

Sutskever instigated a virtual meeting with Altman that the rest of the OpenAI board attended except Brockman, the now-former OpenAI president claimed in the X post. It was during this meeting that Sutskever allegedly fired Altman, telling him “that the news was going out very soon,” Brockman wrote.

Less than half-an-hour later, Brockman claimed to have received a text message from Sutskever, in which the chief scientist summoned for another virtual meeting. At this meeting, Brockman said he learned of Altman’s firing and that he was being removed from OpenAI’s board, but was assured to be “vital to the company and would retain his role.”

“As far as we know, the management team was made aware of this shortly after, other than Mira who found out the night prior,” Brockman said in the post, which was quickly followed by a separate message from Altman.

Altman said in an X post that “today was a weird experience in many ways. but one unexpected one is that it has been sorta like reading your own eulogy while you’re still alive.”

“if i start going off, the openai board should go after me for the full value of my shares,” Altman said in another X post.

OpenAI debuted in 2015 as a nonprofit and employed Sutskever as research director and Brockman as chief technology officer. The firm’s original investors included several prominent Silicon Valley luminaries like Altman, LinkedIn co-founder Reid Hoffman and Tesla CEO Elon Musk, who reportedly committed $1 billion to the project.

Before taking over as CEO, Altman, 38, was president of startup accelerator Y Combinator and gained prominence in Silicon Valley as an early-stage investor. Earlier in his career, he started the social networking company Loopt.

As OpenAI’s popularity grew this year alongside ChatGPT, so too did Altman’s profile. He became an ambassador of sorts, representing the ballooning AI industry across the globe.

In September, Indonesia awarded Altman the so-called “Golden Visa,” providing him with 10 years worth of various travel accommodations and perks intended to help the country gain more foreign investors.

Altman visited several Asia-Pacific countries over the summer including Singapore, India, China, South Korea and Japan, meeting with government leaders and officials and giving public speeches on the rise of AI and the need for regulations.

The technologist testified before the U.S. Senate in May, calling on lawmakers to regulate AI, citing the technology’s potential to have a negative impact on the job market, the information ecosystem, and other societal and economic concerns.

“I think if this technology goes wrong, it can go quite wrong,” Altman said at the time. “And we want to be vocal about that. We want to work with the government to prevent that from happening.”

In a prelude to his Senate testimony, Altman also spoke at a dinner with roughly 60 lawmakers, who were reportedly wowed by his speech and demonstrations.

“It’s not easy to keep members of Congress rapt for close to two hours,” said Rep. Ted Lieu, D-Calif., vice chair of the House Democratic Caucus, who co-hosted the dinner with GOP Conference Vice Chair Mike Johnson, R-La., now House speaker. “So Sam Altman was very informative and provided a lot of information.”

More recently, Altman spoke this week at the Asia-Pacific Economic Cooperation conference in San Francisco, along with various technology executives and world leaders including U.S. President Joe Biden and Chinese President Xi Jinping.

OpenAI held its first developer conference in early November, underscoring the startup’s rising popularity in the technology industry. Microsoft CEO Satya Nadella made a surprise guest appearance during the event, joining Altman on stage to discuss the startup’s AI technologies and its partnership with Microsoft.

Altman didn’t immediately respond to a request for more information.
