Fixing Hallucinations Would Destroy ChatGPT, Expert Finds

In a paper published earlier this month, OpenAI researchers said they'd found the reason why even the most powerful AI models still suffer from rampant "hallucinations," in which products like ChatGPT confidently make assertions that are factually false. They found that the way we evaluate the output of large language models, like the ones driving ChatGPT, means they're "optimized to be good test-takers" and that "guessing when uncertain improves test performance." In simple terms, the creator

The 2025 Emmys Are Tonight. Here’s Everything You Need To Know

The biggest night in television is finally here. The 77th edition of the annual Primetime Emmy Awards will be given out on Sunday night. The best shows that came out sometime between June 2024 and May 2025 will be awarded across categories. Apple TV+ is the big winner so far when it comes to nominations. Its fan-favorite show Severance picked up a total of 27 nominations. Lead actors Adam Scott and Britt Lower, who play Mark and Helly on the show, are both nominated for best actor nominations

OpenAI Realizes It Made a Terrible Mistake

OpenAI claims to have figured out what's driving "hallucinations," or AI models' strong tendency to make up answers that are factually incorrect. It's a major problem plaguing the entire industry, greatly undercutting the usefulness of the tech. Worse yet, experts have found that the problem is getting worse as AI models get more capable. As a result, despite incurring astronomical expenses in their deployment, frontier AI models are still prone to making inaccurate claims when faced with a pr

Are bad incentives to blame for AI hallucinations?

A new research paper from OpenAI asks why large language models like GPT-5 and chatbots like ChatGPT still hallucinate, and whether anything can be done to reduce those hallucinations. In a blog post summarizing the paper, OpenAI defines hallucinations as “plausible but false statements generated by language models,” and it acknowledges that despite improvements, hallucinations “remain a fundamental challenge for all large language models” — one that will never be completely eliminated. To ill

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

Here’s how we picked this year’s Innovators Under 35

We’ll also soon reveal our 2025 Innovator of the Year, whose technical prowess is helping physicians diagnose and treat critically ill patients more quickly. What’s more (here’s your final hint), our winner even set a world record as a result of this work. MIT Technology Review first published a list of Innovators Under 35 in 1999. It’s a grand tradition for us, and we often follow the work of various featured innovators for years, even decades, after they appear on the list. So before the big

Hallucinations in AI Models: What They Mean for Software Quality and Trust

Modern businesses are rushing to adopt artificial intelligence (AI) technologies, but this rapid integration comes with unexpected challenges. A phenomenon known as “hallucinations” occurs in large language models (LLMs) and deep learning systems and threatens software quality and trust. These hallucinations occur when AI presents false information as fact. The damage extends beyond technical failures, as user trust erodes, brand reputations suffer, and ethical questions multiply. Practical appr

Apple TV+ might have just beaten HBO at its own game

During its nearly six years on the market, Apple TV+ has been referred to by some as “the new HBO.” But this year might be when Apple has truly started to prove that claim. Here’s why. Emmy nominations show Apple TV+ ahead in quality, while HBO boasts higher quantity Whatever your opinion of Apple TV+, it’s hard to dispute that 2025 has been an especially good year for the streamer. Apple TV+ has achieved new levels of both mainstream awareness and critical success. It’s putting out consisten

Open source X rival Mastodon begins raising funds with new in-app donation feature

Open source X and Threads competitor Mastodon will begin experimenting with a new way to raise funds: in-app donations. The organization on Wednesday announced it’s launching a campaign that introduces banners inside its Android and iOS apps, prompting users to make a monetary donation. Initially, the feature will be shown only to those on the Mastodon servers the nonprofit itself operates, Mastodon.social and Mastodon.online. These banners will be easy to dismiss, Mastodon says, and will only

Voting age to be lowered to 16 in UK by next general election

The voting age will be lowered to 16 across the UK by the next general election in a major change of the democratic system. The government said it was a reform to bring in more fairness for 16- and 17-year-olds, many of whom already work and are able to serve in the military. It brings the whole of the UK voting age to 16. Scotland and Wales have already made the change for Holyrood and Senedd elections, as well as local council elections. In a sweeping package of changes, ministers will also

Severance, The Last of Us and Andor just nabbed dozens of Emmy nominations

This is thanks to the second season of The Last of Us , with 16 nominations, and the Batman-adjacent The Penguin. The White Lotus, The Pitt and Hacks also g
