An artificial intelligence watchdog is accusing OpenAI of training its default ChatGPT model on copyrighted book content without permission. In a new paper published this week, the AI Disclosures Project alleges that OpenAI likely trained its GPT-4o model using non-public material from O’Reilly Media. The researchers used a legally obtained dataset of 34 copyrighted O’Reilly books and found that GPT-4o showed “strong recognition” of the company’s paywalled content. By contrast, GPT-3.5 Turbo appeared more familiar with publicly accessible O’Reilly book samples. “These results highlight the urgent need for increased corporate transparency regarding pre-training dat…

Finding fulfilling and motivating work is a challenge for many people, but it can be especially difficult for those just starting their careers. And as Generation Z professionals—those born between 1997 and 2012—increasingly seek personalized career paths, managers are tasked with helping employees find meaning in their roles while also meeting organizational goals. Some managers may view Gen Z’s desire for meaningful work as a form of entitlement, but dismissing it can be costly. Research shows that employees who find their work meaningful experience greater job satisfaction, which directly boosts productivity. Meanwhile, ignoring this need can lead to higher employe…

In 2024, Amazon introduced its AI-powered HR assistant, which helps managers with performance reviews and workforce planning. Similarly, Tesla deployed AI personas to assist in real-time production monitoring and supply chain optimization. These advancements showcase how AI personas are becoming essential in business operations, streamlining processes, and enhancing decision-making. As artificial intelligence evolves, we’re witnessing two interrelated phenomena shaping our future: AI personas and agentic AI. These developments bring both opportunities and challenges. Understanding AI Personas AI personas are collections of digital elements that combine to form …

Online applications usually include an optional field where you can upload a cover letter. Think “optional” means you don’t have to include one? Think again. According to a recent survey of recruiters from the career services platform Zety, 89% expect a cover letter, and 87% say it’s a key factor when deciding whom to interview. “Job applications are super complicated today,” says Jasmine Escalera, Zety’s career expert. “You have to tailor your résumé to the job, and there are often so many moving parts to just submit one application. I understand when job seekers think, Does the cover letter actually add any value? Sometimes it can be equally as important as résumés …

Even as paid family leave has stalled at the federal level, a growing number of states have taken up the issue in recent years. Thirteen states and Washington, D.C., have now passed legislation that makes paid leave mandatory, while a handful of other states have also introduced voluntary systems that leave it to private insurance companies and employers to opt into the benefit. Despite those legislative wins, however, a new report by the nonprofit Moms First and McKinsey indicates that many eligible workers in states with mandatory paid leave are not taking advantage of their access to the benefit. The analysis focused on the paid-leave programs in New York, New Jers…

Hundreds of thousands of people—including me—are heading to Austin, Texas, for the SXSW Conference and Festivals to learn, share, and meet others who are eager to propel business and culture forward. In perusing the lineup for this year’s conference, I was pleasantly surprised. In addition to Understood.org’s session, the agenda has half a dozen panels or meetups focused on some flavor of neurodiversity—from the science behind neuroinclusive office design to learning to “love your tricky brain.” As a neurodivergent leader at Understood.org, I often find myself the lone neurodiversity advocate in professional settings—creatively connecting dots to make the business…

TikTok and Instagram are flooded with reels of food influencers hyping already viral restaurants or bringing hundreds of thousands of eyes to hidden gems. With sauce-stained lips, exaggerated chewing, and that signature hooked finger over their mouth, they urge viewers to “run, don’t walk” to these must-try spots. But how trustworthy are these glowing reviews? Platforms like Yelp and Google Reviews long ago opened the door for anyone with an internet connection to play food critic. But the rise of short-form video has democratized the food-reviewing game to a whole new level. OnTikTok and Instagram, driving engagement is the name of the game, and posting hyperbolized …

Nvidia forecast first-quarter revenue above market estimates on Wednesday, expecting robust demand for its leading AI chips to persist as businesses spend heavily to expand generative artificial intelligence infrastructure. Its shares rose about 1% in choppy extended trading, after closing up 3.7% in regular trading. Nvidia is the biggest beneficiary of a rally in AI-linked stocks, with its shares up more than 400% over the last two years. The company expects revenue of $43 billion, plus or minus 2% for the first quarter, compared with analysts’ average estimate of $41.78 billion according to data compiled by LSEG. Demand has grown unabated for Nvidia’s advanc…

Americans often receive a lot of grief for being less internationally traveled than citizens of other countries. But in recent years, more Americans are traveling abroad than ever before. Numbers compiled by the digital magazine Travel and Tour World (TTW) show that in March 2025, 6.56 million Americans flew outside of the country. That’s 1.6% more than the same period a year earlier, and more than 22% more than in 2019—the year before the pandemic caused international travel to grind to a halt. TTW cites “pent-up demand, strong personal savings among affluent demographics, and a growing appetite for immersive cultural experiences” as the main reasons more Americans a…

The contributions of Black Americans built the nation’s economic foundation, sustained industries, and shaped countless communities. Yet, even today, disparities in the workplace persist, limiting the opportunities available to Black professionals, which has been exacerbated by the recent White House Executive Order to terminate all Federal DEI programs and positions. Black employees comprise 12.8% of the workforce but hold just 7% of managerial positions. In senior leadership, representation drops to 4–5%. These numbers are beyond dismal and reveal more than gaps in representation—they reflect systemic barriers that prevent Black talent from reaching their full poten…

From the moment Chuck Yeager broke the sound barrier for the first time in 1947, zipping from New York to Paris in less than three hours became every traveler’s dream. It’s a dream that shattered as soon as everyone realized supersonic flight was really annoying for people on the ground. That’s why NASA and Lockheed Martin created the X-59 Quesst, which was designed with an aerodynamic profile that would reduce the eardrum-breaking boom to a dull thump. NASA’s upcoming test flight was supposed to be the first silent supersonic flight in history—then January 28 happened. That’s when the startup company Boom Supersonic flew a supersonic flight over the Mojave Desert, in…

Companies are spending more than $65 billion globally on corporate wellness, offering everything from meditation rooms and resilience webinars to nap pods and self-help apps. Projections suggest this market will exceed $100 billion by 2032. And yet burnout is worse than ever. Post-pandemic, 77% of U.S. employees report experiencing workplace stress, according to the American Psychological Association, and 82% say they’re at risk of burnout. Experts blame collaboration overload, digital fatigue, and blurred work-life boundaries. Even artificial intelligence tools like ChatGPT, intended to streamline work, can amplify pressure by raising expectations for speed and o…

The upside of friends, roommates, or family members sharing a multiline phone plan is everyone has a lower monthly bill. The downside, however, is one person is ultimately responsible for both paying that bill—and gathering what is owed to him or her from their friends each month. AT&T is offering a new way to divvy things up, though. The carrier, on Thursday, will introduce AT&T SplitPay, which will individually bill people on select shared wireless plans. The service will be available immediately. “College kids are Venmo-ing each other to share accounts,” says Erin Scarborough, AT&T’s President of Broadband & Connectivity Initiatives. “They’re h…

Police in Munich are investigating a mystery: More than 1,000 stickers were put on gravestones and wooden crosses at three cemeteries in the German city, without any indication of where they came from or why. The 5×3.5-centimeter (1.95×1.2-inch) stickers are printed with a QR code, that, when scanned, shows the name of the person buried in the grave and its location in the cemetery — but nothing else. “We haven’t found any pattern behind this yet. The stickers were put both on decades-old gravestones and very new graves that so far only have a wooden cross,” police spokesperson Christian Drexler told The Associated Press on Wednesday. “People who have witnesse…

As a child, Sunita Sah says she learned to be “good.” Growing up in the U.K. in the 1980s as the daughter of Indian immigrants, she was praised for being obedient and studious at home and at school. But she also experienced racial slurs and hostile stares. Sah lived in a place that didn’t always welcome differences—and her family was different. Sah had long considered her mother to be a compliant person. Quiet and deferential, her mom was the model of goodness. But one day that changed. When Sah was 7 years old, she and her mother were accosted in an alley by teenage boys, who shouted at them to “Go back home.” They were alone, vulnerable, and outnumbered. That’s…

In the past five years, more satellites have been launched into Earth’s atmosphere than the preceding 60 years combined. And now, scientists believe that climate change is set to increase the number of old satellites that will turn into floating obstacles. That’s according to a study published last week in the Nature Sustainability journal by a team of aerospace engineers at MIT. The researchers examined how greenhouse gases are impacting Earth’s upper atmosphere and, in turn, the objects orbiting within it. They found that, as emissions increase, they’re actually altering the natural process that allows satellites to fall out of orbit and disintegrate, resulting in a…

Birkenstock, the renowned German footwear brand, posted stronger-than-expected sales for its fiscal first quarter, fueled by strong holiday demand and the growing popularity of its closed-toe clogs. However, the company’s U.S.-listed shares (NYSE: BIRK) were down about 3% in premarket trading Thursday as of the time of this writing. Strong demand meets investor skepticism The company reported quarterly revenue of €361.7 million, exceeding analyst expectations of €356.2 million. However, it maintained its annual margin forecast, as Reuters reported. The drop in share price is likely related to a cautious outlook on profit margins for fiscal 2025, with inves…

To promote its newest shoes, the Swiss athletic apparel brand On filmed a fictional movie trailer with Zendaya. Zone Dreamers stars the actress as an elf-eared astronaut who wears athleisure, trains in space with her flight crew, and—On hopes—sells some merchandise. It’s all an elaborate ad campaign for On’s new low-profile sneaker, Cloudzone, its one-piece Studio Knit Bodysuit, and other offerings from the company’s Spring/Summer 2025 Movement Lifestyle collection, which Zendaya wears throughout. (Consumers hoping to get their hands on the futuristic space suit Zendaya sports in one scene will be disappointed to learn that it’s not part of the collection. Celebrity s…

Thinking Machines Lab, an AI startup founded by former OpenAI Chief Technology Officer Mira Murati, has tapped about 30 leading researchers and engineers from competitors such as OpenAI, Meta and Mistral, it said in a blog post on Tuesday. The team — roughly two-thirds of which comprises former OpenAI employees — includes Barret Zoph, a prominent researcher who left the ChatGPT maker on the same day as Murati in late September. Zoph will serve as the startup’s technology chief. OpenAI co-founder John Schulman is the startup’s chief scientist. Schulman left OpenAI for rival Anthropic in August, citing wanting to “focus on AI alignment”. AI alignment refers to a…

As we enter spring, the days may be getting longer, but the average workday seems to be contracting. Corporate employees in the U.S. now seem to be ending their day at 4:39 p.m., according to a new report by the workforce analytics platform ActivTrak. That’s more than 40 minutes earlier than when workers clocked out just two years prior. While employees still start their day on average just before 8 a.m., the average length of the workday has dropped to about eight hours and 44 minutes. The report, which looked at data from nearly 220,000 workers at 777 companies, indicates that productivity has actually increased by 2% despite the slight reduction in time worked. Som…

From the southwestern U.S. to Minnesota, Iowa and even parts of New Jersey, it seemed that winter never materialized. Many communities marked their driest winters on record, snowpack was nearly nonexistent in some spots, and vegetation remains tinder dry—all ingredients for elevated wildfire risks. More than 1,000 firefighters and fire managers recently participated in an annual wildfire academy in Arizona, where training covered everything from air operations to cutting back brush with chain saws and building fire lines. Academy officials say there’s consensus that crews will be busy as forecasts call for more warm and dry weather, particularly for the Southwest.…

Flashes, a photo-sharing app that’s linked to X-alternative Bluesky, launched in beta this week before disappearing from the test store due to what its developer said was technical difficulties. Flashes developer Sebastian Vogelsang said in a Bluesky post that Apple’s engineering team is working on a fix. Apple didn’t immediately respond to Fast Company‘s request for comment. Flashes, which was revealed last month, supports photo posts of up to four images and videos up to one minute long. Items posted on Flashes will also appear on Bluesky. Comments from Bluesky users on the posts will appear back on Flashes. Flashes could be attractive to users who want to …
