IPO hopeful Brex scored major win to sell in the EU, plans UK expansion

Financial services provider Brex on Thursday announced that it achieved a major milestone: it is now licensed in the European Union. That means it can now directly issue credit and debit cards and offer its spend management products to any business in all 30 EU countries with “no workarounds required,” as co-founder and CEO Pedro Franceschi wrote in a blog post. While the corporate spend management startup previously supported 60 currencies in 200 countries, it could only sell its products to c

OpenAI launches new GPT-5 model for all ChatGPT users

"GPT-5 has been trained to recognize when a task can't be finished, avoid speculation and can explain limitations more clearly, which reduces unsupported claims compared to prior models," said Michelle Pokrass, a post-training lead at OpenAI. Instead of outright refusing to answer users' questions if they are potentially risky, GPT-5 will use "safe completions," OpenAI said. This means the model will give high-level responses within safety constraints that can't be used to cause harm. OpenAI s

GPT-5 is here. Now what?

Whereas o1 was a major technological advancement, GPT-5 is, above all else, a refined product. During a press briefing, Sam Altman compared GPT-5 to Apple’s Retina displays, and it’s an apt analogy, though perhaps not in the way that he intended. Much like an unprecedentedly crisp screen, GPT-5 will furnish a more pleasant and seamless user experience. That’s not nothing, but it falls far short of the transformative AI future that Altman has spent much of the past year hyping. In the briefing, A

OpenAI officially announces GPT-5, its next major upgrade to ChatGPT

ChatGPT Is Getting a Big Upgrade. Here's What's New With GPT-5

Expect your ChatGPT experience to get faster and smarter today. OpenAI updated its flagship line of large language models Thursday, unveiling the GPT-5 generative AI model after months of anticipation. While the developer has released a lot of model updates in recent months, including new open-weights models just this week, it's been more than two years since the debut of GPT-4. With a new generation worthy of a new number, how big of a change should you expect? "I tried going back to GPT-4 an

2025 Porsche Panamera Turbo S: A different approach to a luxury sedan

REIDEN, Germany—There is a lot to be said for testing a car on the roads it was developed on. A Kei car, for example, makes more sense in downtown Tokyo than on one of Nashville's arterial highways, surrounded by construction trucks. Likewise the German supersedans. For decades, an arms race has been conducted between rival engineers in Munich, Ingolstadt, Stuttgart, and Zuffenhausen, each trying to best the others and build the ultimate four-door, four-wheel Autobahn crusher, fit for the fattes

PS5 sales have passed the 80 million mark

The PS5 might be lacking the cadence of first-party exclusives that made its predecessor so successful, but that doesn’t appear to be slowing it down. Sony has announced that the console had shifted just north of 80 million units as of June 30, 2025. This puts it just behind the Xbox 360 (84 million) and well on the way to overtaking the PS3 (around 87 million) in lifetime sales. The 80.3 million figure was confirmed in Sony’s first set of quarterly results for the current financial year, durin

Why the US Is Racing to Build a Nuclear Reactor on the Moon

NASA is fast-tracking a plan to build a nuclear reactor on the moon by 2030 under a new directive from the agency’s interim administrator Sean Duffy. The plan revives a decades-old dream of scaling up nuclear power in space, a shift that would unlock futuristic possibilities and test legal and regulatory guidelines about the use of extraterrestrial resources and environments. Duffy, who also serves as President Donald Trump’s secretary of transportation, framed being first to put a reactor on

Instagram adds a new friends map feature that sure looks a lot like the Snap Map

Instagram just announced an update with some long-requested features. The most notable is the introduction of a location-sharing tool for friends, though the long-awaited reposting tool is nothing ot sneeze at, either. Once opted into, the map shares a user's last active location with chosen contacts. The location sharing feature is turned off until selected and there are numerous customization controls. For instance, Instagram users can choose to share location data with all friends, Close Fri

OpenAI nearly confirms GPT-5 launch today - how to tune in

Elyse Betters Picaro / ZDNET ZDNET's key takeaways OpenAI's livestream at 10 AM PT/1 PM ET will likely launch GPT-5. GPT-5 will automatically select the best model for prompts, improving efficiency. That approach should help produce higher-quality answers more quickly. OpenAI just launched its highly anticipated open-source models on Tuesday, but the company is already moving on to what will likely be its biggest product launch of the year: GPT-5. Also: How ChatGPT actually works (and why

Let's stop pretending that managers and executives care about productivity

Let's stop pretending that managers and executives care about productivity I’ve just been on a bit of a summer break. Did a bit of travel locally. Visited Hvalfjörður. Walked a lot. I know from experience that if I don’t take a summer break, the winter becomes more of a slog and my thoughts become groggier. Often, as soon as you rest, your mind starts to “helpfully” come up with ideas to help fill your time. One of the invasive thoughts that kept prodding my brain during my break was about mo

NASA Told to Overhaul Its Plans to Replace the International Space Station

For nearly 30 years, the International Space Station has played orbital home for astronauts from all over the world, but its time is running out. Slated to retire in 2030, NASA is aiming to replace it with a privately-run station that can host its astronauts in space when needed. And now under pressure to get a new station up and running fast and within a slashed budget, NASA’s current head—U.S. Transportation Secretary Sean Duffy—is completely overhauling the agency’s plans to replace the ISS.

Narwal’s Self-Cleaning, AI-Enhanced Robot Vacuum and Mop From CES Is Finally Ready to Buy

Narwal has a pretty extensive lineup of robot vacuums, many of which we’ve tested in our roundup of the best robot vacuums. One of the latest additions to the lineup is the Narwal Flow, first announced at CES 2025. As the name suggests, the Flow is another high-end robot vacuum that focuses on mopping, but it also comes with more advanced AI navigation and the ability to self-clean and detangle itself. It’s now available for sale at $1,499 full price and $1,099 for presale. According to Narwal

OpenAI Is About to Make Employees Millionaires

It’s a figure so large it almost loses meaning: $500 billion. That is the staggering valuation OpenAI, the company behind the revolutionary ChatGPT, could soon command. The company is in discussions with investors for a deal that would allow its current and former employees to sell their privately held shares, a source familiar with the matter told Gizmodo. This type of deal, known in financial jargon as a secondary sale or a tender offer, would more than double OpenAI’s recent $260 billion val

NASA Rewrites the Rules for Developers of Private Space Stations

About five years from now, a modified Dragon spacecraft will begin to fire its Draco thrusters, pushing the International Space Station out of its orbit and sending the largest object humans have built in space inexorably to the bottom of the Pacific Ocean. And then what? China’s Tiangong Space Station will still be going strong. NASA, however, faces a serious risk of losing its foothold in low-Earth orbit. Space agency leaders have long recognized this and nearly half a decade ago awarded abo

What the world's biggest chipmakers are doing to stave off Trump's tariffs

U.S. President Donald Trump speaks during an event with Apple CEO Tim Cook in the Oval Office of the White House on August 6, 2025 in Washington, DC. U.S. President Donald Trump's proposed 100% tariffs on the import of semiconductors has brought major chip names into the spotlight. Questions linger about how these duties will be implemented: will they apply to the raw chip itself that is imported, or the end product, like a smartphone or laptop? And how much manufacturing needs to actually be

How to watch OpenAI’s ‘longer than usual’ GPT-5 reveal, as teased by a Death Star

“That’s no moon,” as Obi-Wan Kenobi once said. OpenAI CEO Sam Altman stirred intrigue with a cryptic post last night showing the Death Star from Star Wars as a hint that something big is coming. That “something big” is undoubtedly GPT-5, OpenAI’s latest frontier model coming to ChatGPT. The company shared a less ambiguous post on X yesterday teasing the upcoming livestream. Since then, Altman has added that OpenAI’s next livestream will be “longer than usual” with a runtime of “about an hour.”

Ceretone Core One Pro Hearing Aids Review: A Blunt Instrument

Ceretone, born on Indiegogo, hit the scene last year with impressively tiny hardware that still remains one of the smallest and lightest hearing aids I’ve ever reviewed. At just 0.96 grams each, the Ceretone Core One were so light they threatened to blow away in the wind. With a price of $349 per pair, they had a similarly minimal effect on your bank account. The trouble with the original Ceretone Core One is that they just weren’t very good as hearing aids. They were not tunable, suffered from

The greenhouse gases we’re not accounting for

Researchers around the world set to work unraveling the mystery, reviewing readings from satellites, aircraft, and greenhouse-gas monitoring stations. They eventually spotted a clear pattern: Methane emissions had increased sharply across the tropics, where wetlands were growing wetter and warmer. That created the ideal conditions for microbes that thrive in anaerobic muck, which gobbled up more of the carbon-rich organic matter and spat out more methane as a by-product. (Reduced pollution from

OpenAI’s GPT-5 leaks, hinting at better math and coding abilities

Calvin Wankhede / Android Authority TL;DR Details about OpenAI’s upcoming GPT-5 model have leaked. GitHub accidentally published details of the upcoming model and its four variants in a blog, which was later withdrawn. The leak points to better reasoning and improved agentic capabilities that may also come to ChatGPT after the model’s release. OpenAI’s long-awaited GPT-5 models are expected to arrive very soon, and are likely to be available through APIs before ChatGPT. But a recent leak has

RFK Jr. defends $500M cut for mRNA vaccines with pseudoscience gobbledygook

If anyone needed a reminder that US health secretary and fervent anti-vaccine advocate Robert F. Kennedy Jr. has no background in science or medicine, look no further than the video he posted on social media Tuesday evening. In the two-and-a-half-minute clip, Kennedy announced that he is canceling nearly $500 million in funding for the development of mRNA-based vaccines against diseases that pose pandemic threats. The funding will be clawed back from 22 now-defunct contracts awarded through the

Microsoft accidentally confirms GPT-5, GPT-5-Mini, GPT-5-Nano ahead of launch

OpenAI is hosting a live stream at 10AM PT to announce GPT-5, but Microsoft has already confirmed the details. In a GitHub document, which has now been taken offline, Microsoft confirmed GPT-5 is launching later today. While it was obvious, this is the first official confirmation. Microsoft also offered more details on GPT-5 models, including the base model, which is called just GPT-5. It is designed for logic and multi-step tasks. We also have GPT-5-mini, which is a lightweight version for c

Tornado Cash sold crypto “privacy”; the US saw “money laundering.”

"Crypto mixers" exist because of a peculiar feature of cryptocurrencies—most are fully traceable using their public blockchain ledgers. To provide more privacy to crypto account owners, a mixer will let people toss their crypto into a large pool, where it is "mixed" with other people's crypto. At a later date, each crypto owner can choose to withdraw their money from the pool into a new, anonymous wallet, thus making the movement of the crypto harder to track. Of course, the obfuscation doesn't

A Single Poisoned Document Could Leak ‘Secret’ Data Via ChatGPT

The latest generative AI models are not just stand-alone text-generating chatbots—instead, they can easily be hooked up to your data to give personalized answers to your questions. OpenAI’s ChatGPT can be linked to your Gmail inbox, allowed to inspect your GitHub code, or find appointments in your Microsoft calendar. But these connections have the potential to be abused—and researchers have shown it can take just a single “poisoned” document to do so. New findings from security researchers Mich

Bob Iger Insists Disney’s Focus Is on Original Movies—but Is It?

A glance at the list of announced films coming from Walt Disney Studios—including Disney’s live-action and animated divisions, plus Pixar, Marvel, Lucasfilm, 20th Century Studios, Searchlight Pictures, and more—will tell you a few things. The biggest is that the upcoming slate leans heavily toward sequels, reboots, remakes, and new entries in well-known series, something the company’s CEO, Bob Iger, seemed to hedge against in a recent earnings call. “I wouldn’t say that we’ve got a priority one
