OpenAI has trained an elite hacker, then locked it in a cage. Its whole job is to break OpenAI’s own AI. The company says it is too dangerous to let anyone else near it.

The model is called GPT-Red, and OpenAI detailed it this week. It is an automated red-teamer: software that hunts for ways to hijack or sabotage other AI systems, so the holes can be patched before release. Humans have long done this work by hand. It is OpenAI’s deepest push yet into automating its own AI security, and GPT-Red does it at machine speed.

OpenAI aimed it at prompt injection, where hidden instructions, buried in an email, a web page, or a file, trick a model into doing something it should not. Then it set the hacker loose on real targets.

The training dojo

GPT-Red learns by fighting. OpenAI put it in a self-play loop against a squad of defender models. GPT-Red is rewarded for landing an attack; the defenders for fending one off. As the defenders wise up, GPT-Red must invent nastier tricks. OpenAI says it poured some of its largest ever compute runs into the model, an amount it calls unprecedented for safety work.

It got good. Speaking to MIT Technology Review, the team said GPT-Red found a whole new class of attack they had never seen, which they call a “fake chain of thought.” It plants a false note in a model’s private working memory, tricking it into trusting something that is not true.

“It’s like if I told you that 1+1=3 and that you have verified this already,” said OpenAI researcher Chris Choquette-Choo. “The model’s like, ‘Oh, okay, of course,’ and it just spits out 3.”

Hacking the vending machine

The tests got physical. In one, GPT-Red attacked Vendy, an AI agent that runs a real vending machine in OpenAI’s office, built by Andon Labs. It changed the prices, marked a pricey item down to the 50-cent minimum, and cancelled a customer’s order. OpenAI says it has disclosed the flaws.

The scores are striking. Against an older GPT-5, more than 90% of GPT-Red’s strongest attacks worked. Against the new GPT-5.6, fewer than 23% did. In a rerun of a 2025 test, GPT-Red beat human red-teamers hands down, cracking 84% of scenarios to their 13%.

Kept in a cage

OpenAI trained GPT-5.6 against GPT-Red, and calls it its most robust model yet against prompt injection. But it will not hand out the attacker itself, so its skills stay clear of real agent hijackers. It is not the first lab to build something and decide against releasing it.

“It’s not a trivial thing that someone could easily do,” Choquette-Choo said, “just go and train a super-attacker using this idea.”

GPT-Red still has blind spots. It is weak at drawn-out, back-and-forth attacks, and at hiding instructions inside images. And human testers keep catching things it misses. “I think human expertise will still be very important,” said Jessica Ji, an AI security analyst at Georgetown’s CSET.

The bigger idea is a flywheel: use today’s models to harden tomorrow’s. OpenAI already does this to make its AI smarter. Now it wants safety to scale just as fast. A full paper is due later this week.

The end of the biggest World Cup ever is almost here. Following 100 matches, there are just four teams left and two more games to play.

The tournament has been hosted by three countries: Mexico, Canada, and the US. All of those host countries are now out of the running. The final teams are France, Spain, England, and Argentina. Those teams will play two more games: one to determine who gets third place, and a final match to decide the winner and the runner-up.

Going into this year’s World Cup, FIFA anticipated that it would be the most watched tournament in the organization’s history. As the tournament moved into the quarterfinals earlier this month, FIFA noted that more than more than 6.2 million people had attended matches in person, “while millions more follow the action across digital platforms, broadcast, and fan experiences in host cities and around the world.”

You can find the full schedule, which defaults to your local time zone, on the FIFA website.

Here’s how to watch the final games.

Final

The World Cup final game will be Spain vs. Argentina at 3 pm EDT on Sunday, July 19, in the New York/New Jersey Stadium.

The game will also feature the first-ever Super Bowl–style halftime show in World Cup history, with performances from Justin Bieber, Madonna, Shakira, BTS, and Gustavo Dudamel. As the name implies, that will likely land right in the middle of the broadcast, so aim to watch somewhere around 4 pm EDT on July 19.

Third Place Playoff

Third place is decided by a match between the two losing teams of the semifinal matches. France and England will face off for the bronze title at 5 pm EDT on Saturday, July 18, in the Miami Stadium in Miami, Florida.

Where to Stream

If you have satellite TV or cable service, you can watch the final kickoffs live on TV via Fox Sports in the US. The games are also available on the FoxOne streaming service for $20 per month.

FIFA has partnered with YouTube as its “preferred partner” for streaming the games. You’ll need YouTube TV’s sports plan, which is currently $55 per month. Other paid options include Fubo ($46 per month) and Hulu’s live sports option ($90 per month).

In partnership with Telemundo, Peacock is streaming all of the games in Spanish. You can find all the official broadcasters on the FIFA website.

New Competition

This World Cup has been huge, competition-wise, as it is the first to include 48 teams in the tournament instead of the 32 for past World Cups. Given the increased number of teams, the structure for how the competition played out was different from past World Cups. Countries were first sorted into groups (labeled with letters A–L) and played out games in the First Stage within those groups.

Winners of those matches went on to duke it out in the stage called the Round of 32, then got whittled down in a Round of 16. After that, the winners moved on to the quarterfinals, which wrapped up last weekend. The semifinals concluded with Argentina beating England on Wednesday, July 15,

Smoke from devastating wildfires in Canada is blanketing a large swath of the Midwest and Northeast this week, causing cities across the region to issue air quality warnings.

The extreme levels of smoke mean that even able-bodied adults would be wise to take some precautions to protect their health. The increasing severity of wildfires across the continent—driven in part by climate change—means that even places where blazes aren’t burning will still suffer the impact.

More than 100 fires are burning out of control across Canada as of Wednesday, with hundreds more being monitored or battled. The smoke has drifted south and east, turning skies hazy from Minnesota to New York. Particularly dramatic images have emerged from Toronto, where commuters went to work on Wednesday morning under orange skies. The region is also dealing with a heat wave, with temperatures well above 90 degrees Fahrenheit in many areas and an even higher heat index.

On Wednesday evening, the air quality index in New York City topped out at 180, putting the city’s air squarely in the “unhealthy” category as defined by the US Environmental Protection Agency. Other places were even worse off, with Duluth, Minnesota, seeing its AQI top out above 500. (Anything over 301 is labeled “hazardous” and considered unsafe for everyone.) Smoky conditions are expected to worsen in parts of the Northeast US on Thursday, including New York.

The wildfire smoke blanketing the area contains microscopic particles of matter known as PM2.5s—shorthand for particles that are smaller than 2.5 micrometers, or 30 times smaller than the width of a human hair.

Exposure to PM2.5s can trigger or worsen a number of medical conditions, especially in vulnerable populations. Nicholas Nassikas, a pulmonologist and assistant professor of medicine at Harvard Medical School, says that he would tell his patients with preexisting conditions, like asthma or lung disease, to limit their time outside. Children “have a faster breathing rate—they just breathe more,” says Nassikas, while the elderly, who often have compounding conditions and may live in less well ventilated homes and senior centers, are also at risk.

Jennifer Stowell, an assistant professor at the University of Maryland’s School of Public Health, says that even healthy adults may want to take precautions on days when the air quality index goes over 100: “At the very least, it is important to limit your time outdoors to reduce your overall exposure.” she says. If you have to be outside for long periods, she recommends wearing an N95 mask. Stowell, who is currently in Boston, where the AQI hit 110 on Wednesday, says she wasn’t planning on attending outdoors events until the evening.

Dan Westervelt, an associate professor of climate physics at Columbia University, is similarly cautious. “I’m going to make sure my kids are staying indoors today,” he says. “I won’t be doing any physical exertion, like running, today or tomorrow.”

Climate change is driving up temperatures. That’s making wildfire season longer and creating hotter, drier conditions that lead to more explosive fires. A study published last year estimated that wildfire smoke already causes 40,000 deaths per year in the US, and could more than double to 70,000 deaths per year by 2050 if warming continues. As bad-air-quality days from wildfire smoke get more common, the research on prolonged exposure to that smoke is still developing. A similar blast of smoke from Canadian wildfires hit the Northeast in 2023.

“Exposure to high levels of air pollution over the course of a lifetime or a long period of time is demonstrated numerous times in research to lead to premature mortality,” says Westervelt. “You can chop off some months of your life expectancy if you are living in conditions where you’re very frequently exposed to high levels of air pollution.”

The headphone company Skullcandy has a reputation for lackluster audio quality. For the past year or so, it’s been on a mission to improve that reputation.

Its efforts started with a Bose partnership in 2025 and the release of the Skullcandy Method 360 ANC, a $130 pair of wireless earbuds that have surprisingly decent audio quality and noise cancellation for the money.

Next on the upgrade list are Skullcandy’s notorious Crusher headphones. These wireless cans have been around for more than a decade, and they are notable for letting users crank up the bass vibrations using a physical thumb wheel on the ear cup. Roll that wheel all the way, and the Crushers rumble and vibrate against your skull, thanks to a special driver design.

The company announced a new pair, the Crusher 1080 ANC, during an event in New York City on Wednesday evening. They’re on sale now.

The headphones emulate the feel of a thumping subwoofer—as if you’re in the front row of a concert—while usually sacrificing the mids and highs. But that’s what Skullcandy wants to correct with the new headphones, once again by heavily relying on Bose’s audio expertise.

The new Crusher headphones are the next step in Skullcandy’s brand-reinvention efforts.

Skullcandy likes to tout that its first product was born on a ski chairlift in 2003 near its headquarters in Park City, Utah. Ever since, the company has specifically catered to the board sports community.

“From snowboarders for snowboarders,” Brian Garofalow, Skullcandy CEO, tells WIRED. Even though private equity firm Mill Road Capital now owns the company, Skullcandy is still seen more as a lifestyle brand than an audio company with serious audiophile chops.

“We’ve been really, really great at community building and nurturing and helping push cultures forward—not the greatest at the engineering part of innovation with products,” Garofalow says. “So we’ve really been honing our chops in the last few years.”

Garofalow says it has been an engineering challenge to pair the company’s proprietary Crusher bass-boosting technology with noise canceling. He says the team worked with Bose’s engineers to decouple Crusher from the rest of the acoustic tuning profile so that the low end sits on its own. Theoretically, this means that when you crank up the bass effect with the dial, the “mids and highs are still way, way sharp, versus in the past, when they tended to get muddy,” Garofalow says.

The Sound by Bose program adds three other improvements to Skullcandy’s new Crusher headphones: Bose’s noise-canceling chops, which will supposedly work well even if you have the bass cranked to 11; Bose’s spatial audio profile for a surround-sound-like feel; and a six-microphone array for call quality that Bose has come to be known for.

Apple has introduced 36-month carrier financing for cellular iPads purchased directly from the Apple Store. The option is available through AT&T and Verizon to existing customers who add a new line of service.

Until now, the main financing option offered directly by Apple was Apple Card Monthly Installments, which divides the cost of an iPad across 12 months. The new carrier plans stretch those payments across three years and cover the standard iPad, iPad mini, iPad Air, and iPad Pro.

The higher prices are easier to swallow

The new option arrives only weeks after Apple raised prices across its iPad lineup, and the sticker shock appears to have become significant enough for the company to offer buyers another way to pay. A cellular 11-inch iPad Pro now starts at $1,399. Apple Card financing works out to $116.58 per month for one year, while AT&T or Verizon financing reduces the hardware payment to roughly $39 per month for three years (via 9to5Mac).

The installment will appear on the customer’s carrier bill alongside the cost of cellular service. Buyers get the iPad without paying the full amount upfront, Apple completes the sale, and the carrier gains a new line from an existing subscriber. There is one important catch. Anyone who cancels the line or switches carriers before the iPad is paid off will need to clear the remaining device balance. Once the balance is settled and the carrier’s other requirements are met, the iPad can be unlocked.

Why iPads have become more expensive

Apple has linked its recent price increases to the rising cost of RAM and storage. AI companies are buying huge quantities of memory for data centers, leaving less supply available for consumer electronics. Prices are unlikely to return to normal soon. Until memory costs ease, Apple may lean more heavily on carrier financing for future products that include cellular connectivity.
