What Are AI Hallucinations? Why Chatbots Make Things Up, and What You Need to Know

If you've used ChatGPT, Google Gemini, Grok, Claude, Perplexity or any other generative AI tool, you've probably seen them make things up with complete confidence. This is called an AI hallucination -- although one research paper suggests we call it BS instead -- and it's an inherent flaw that should give us all pause when using AI. Hallucinations happen when AI models generate information that looks plausible but is false, misleading or entirely fabricated. It can be as small as a wrong date i

Galaxy S26 Edge renders show the iPhone 17-like design, corroborate Qi2 magnets [Gallery]

Following an early leak yesterday, a new set of renders has essentially confirmed that the Galaxy S26 Edge will look a lot like Apple’s next iPhone, while apparently also adding Qi2 magnets. Images created by @OnLeaks for Android Headlines show what the Galaxy S26 Edge will look like, based on CAD files used for making accessories for the device. The renders show a device with a drastically different design that includes a full-width camera module, but only two cameras mounted on the far left s

The 7 coolest gadgets I've seen at IFA 2025 (including ones you can actually buy)

Maria Diaz/ZDNET Follow ZDNET: Add us as a preferred source on Google. IFA is Europe's largest consumer electronics show, and this year is no different. IFA 2025 features some of the most eye-catching innovations ever, so much so that it's hard to narrow down the list of amazing products. However, at a time when the tech world is saturated with artificial intelligence (AI) adoption, I found it refreshing that the best products I've seen don't hinge on AI. As I walk through the halls of Messe

I kissed comment culture goodbye

It started out harmlessly, a comment on hacker news roughly 16 years ago. From there it expanded to reddit, substack, twitter. And it increased in frequency, from every few months to every week, peaking at several times a day. It became an addictive, productive habit—I would scan the headlines for a catchy title, quickly skim the piece, and then race to the comment section and type one out. Sometimes the comments were insightful or funny. At other times, curt or nitpicky. It was an exercise of

Eero’s Signal is a cellular safety net for your Wi-Fi network

The new Eero Signal could have saved me a lot of headaches when I was dealing with regular internet outages at my home last year. See, Signal automatically detects when your internet goes down and switches your whole Wi-Fi network over to a cellular connection to minimize disruption. Sure, when I’d suddenly see a “Slack is trying to connect” message, I could pull out my phone and hop on the hotspot, but that only brought my laptop back online. My TVs, the computer in my studio, my kid’s iPad, th

Sam Altman Says He's Suddenly Worried Dead Internet Theory Is Coming True

OpenAI CEO Sam Altman, creator of the most popular AI chatbot on Earth, says he's starting to worry that "dead internet theory" is coming true. "I never took the dead internet theory that seriously," Altman tweeted in his typical all-lowercase style, "but it seems like there are really a lot of LLM-run twitter accounts now." (LLM meaning large language model, the tech which powers AI chatbots.) He was resoundingly mocked. "You're absolutely right! This observation isn't just smart — it shows

Sting operation kills “copycat” sports piracy site with 1.6B visits last year

On Wednesday, a global antipiracy group, which included Apple TV+, Netflix, The Walt Disney Studios, and Warner Bros. Discovery, announced that it had assisted in a sting operation that took down Streameast, described as the “largest illicit live sports streaming operation in the world.” Now, accessing websites from the thwarted Streameast brings up a link from the Alliance for Creativity and Entertainment (ACE) that explains how to watch sports games legally. However, people have reported that

Sony’s CEO on Seeing ‘KPop Demon Hunters’ Become a Big Hit… for Netflix

The success of KPop Demon Hunters has been one of the stories of the summer. Sure, Lilo & Stitch was the highest-grossing movie at the domestic box office. Yes, Superman did well enough to launch the DC Universe. And of course, it was awesome to see an original genre film like Weapons clean up. But above all that, it’s the animated musical that became not only Netflix’s biggest movie ever but also a box office hit in a single weekend that history will look back on with most interest.

Google deletes net-zero pledge from sustainability website

Pichai added that he knew the “road ahead would not be easy,” but Google “aimed to prove that a carbon-free future is both possible and achievable fast enough to prevent the most dangerous impacts of climate change.” “Today, I’m proud to announce that we intend to be the first major company to operate carbon free — 24 hours a day, seven days a week, 365 days a year,” he said, in a video announcement .

JetBlue will use Amazon’s Project Kuiper satellites for free in-flight internet

In Brief Many major airlines are beefing up their in-flight internet offerings by tapping SpaceX’s Starlink satellites, but JetBlue is going in a different direction. Amazon and JetBlue announced Thursday a partnership under which the airline will instead use Amazon’s Project Kuiper satellites to provide free in-flight connectivity starting in 2027. The Kuiper terminals on JetBlue’s planes will be capable of download speeds of up to 1Gbps from Amazon’s low-Earth orbit satellites. That’s more b

NASA Finds Evidence That Mars Devoured Huge Chunks of Other Planets

The Red Planet has a bloody history. Newly examined data from NASA's retired InSight lander suggest that there may be giant chunks of rocky material deep inside the mantle of Mars, which were lodged there after a barrage of massive objects slammed into its surface some 4.5 billion years ago. Some of these smithereens are so large, the researchers say, that they're effectively protoplanets — moon-sized objects in the early stages of becoming a planet proper. In other words: Mars could be stuffe

Amazon launches cellular dongle to provide backup connectivity for eero routers

I Let the Pixel 10's AI Camera Coach Tell Me How to Take Photos and Here Are the Results

If you look through the camera roll on your phone, what kind of photos do you find? I see images of my friends, my pets, the odd receipt for a work expense and snapshots of coffee -- hey, I was a barista for 11 years! Not every photo is meant to rival an Ansel Adams masterpiece. (Though I'm sure if he had a smartphone, he'd also take a pic of his parking space to remember where he parked his car.) If you want to take better photos with your phone, Google has added a new tool to the Pixel 10 cam
