Nvidia chips become the first GPUs to fall to Rowhammer bit-flip attacks

Nvidia is recommending a mitigation for customers of one of its GPU product lines that will degrade performance by up to 10 percent in a bid to protect users from exploits that could let hackers sabotage work projects and possibly cause other compromises. The move comes in response to an attack a team of academic researchers demonstrated against Nvidia’s RTX A6000, a widely used GPU for high-performance computing that’s available from many cloud services. A vulnerability the researchers discove

Humans Are Starting to Talk More Like ChatGPT, Study Claims

For better or worse, the rise of ChatGPT as a writing tool, search engine, or conversational buddy has considerably changed how we communicate with each other and with technology. At the same time, ChatGPT’s widespread use has also sparked numerous online debates about whether it’s possible to spot AI-created content by looking at certain cues, like the em dash. But new research suggests that such AI cues might become increasingly harder to pick out—because we’re starting to speak more like Cha

Experts Warn that People Are Losing Themselves to AI

AI users are spiraling into severe mental health crises after extensive use of OpenAI's ChatGPT and other emotive, anthropomorphic chatbots — and health experts are taking notice. In a recent CBC segment about the phenomenon, primary care physician and CBC contributor Dr. Peter Lin explained that while "ChatGPT psychosis" — as the experience has come to be colloquially known — isn't an official medical diagnosis just yet, he thinks it's on its way. "I think, eventually, it will get there," sai

NVIDIA shares guidance to defend GDDR6 GPUs against Rowhammer attacks

NVIDIA is warning users to activate System Level Error-Correcting Code mitigation to protect against Rowhammer attacks on graphical processors with GDDR6 memory. The company is reinforcing the recommendation as new research demonstrates a Rowhammer attack against an NVIDIA A6000 GPU (graphical processing unit). Rowhammer is a hardware fault that can be triggered through software processes and stems from memory cells being too close to each other. The attack was demonstrated on DRAM cells but i

How I personalized my ChatGPT conversations - why it's a game changer

Elyse Betters Picaro / ZDNET ChatGPT offers several ways to customize and personalize your conversations. You can share details about your life, including your name, your profession, or other tidbits. You're able to tell it what traits it should possess, such as patience, sympathy, or understanding. You can add and save certain facts about yourself and tell it to reference memories from past conversations. That all sounds helpful. But what does ChatGPT do with the information it knows about yo

I'm an AI tools expert, and these are the only two I pay for (plus three I'm considering)

Vstock LLC/Getty Images It's only been almost three years since generative artificial intelligence (AI) hit the mainstream as a new paradigm of productivity, but here we are -- it's everywhere. I test AI tools as part of my work. I'll dig into just about any AI-related technology and see what I can make it do. Many of you have read my ongoing shootouts comparing AIs for programming and AI content checkers, among other kinds of tools. But that's using AI in a rigorous lab environment to provid

These Are the AI Chatbots We Use Most, and Here's How We Use Them

If you have a particular artificial intelligence tool that you turn to, you're not alone. According to a new survey, 91% of people who use AI have a favorite chatbot they try first, whether it's ChatGPT, Gemini, Alexa or something else. A Menlo Ventures survey of 5,000 adults found that this "default tool dynamic" means most people using AI have chosen a general AI tool they'll try first for every job, even if it's not necessarily the best tool for the job. In the report, ChatGPT is the AI ass

ChatGPT made up a product feature out of thin air, so this company created it

On Monday, sheet music platform Soundslice says it developed a new feature after discovering that ChatGPT was incorrectly telling users the service could import ASCII tablature—a text-based guitar notation format the company had never supported. The incident reportedly marks what might be the first case of a business building functionality in direct response to an AI model's confabulation. Typically, Soundslice digitizes sheet music from photos or PDFs and syncs the notation with audio or video

ChatGPT hallucinated about music app Soundslice so often, the founder made the lie come true

Earlier this month, Adrian Holovaty, founder of music-teaching platform Soundslice, solved a mystery that had been plaguing him for weeks. Weird images of what were clearly ChatGPT sessions kept being uploaded to the site. Once he solved it, he realized that ChatGPT had become one of his company’s greatest hype men – but it was also lying to people about what his app could do. Holovaty is best known as one of the creators of the open-source Django project, a popular Python web development fram

Review: BenQ GP520 unlocks Vision Pro movie night vibes for Apple TV 4K, gaming, more

I’ve tested a few BenQ products lately. My favorite has been their Mac monitor with Apple Studio Display specs and a more affordable price. The most fun? A new category for me: projectors. The GP520 4K HDR model BenQ loaned me to test alleviated my concerns about the practicality of a projector instead of a TV. Why this projector feels fun to use What’s so fun about a projector? Watching movies and TV shows with Apple Vision Pro is great. You can recreate the experience of watching video on a

How ChatGPT actually works (and why it's been so game-changing)

Elyse Betters Picaro / ZDNET Back in the day (and by "in the day," I mean late 2022, before AI chatbots exploded on the scene), tools like Google and Wolfram Alpha interacted with users via a single-line text entry field and provided text results. Google returned search results -- a list of web pages and articles that would (hopefully) provide information related to the search queries. Wolfram Alpha generally provided answers that were mathematical and data analysis-related. ChatGPT, by contra

Tyr, a new Rust DRM driver targeting CSF-based ARM Mali GPUs

The last year has seen substantial progress on the DRM infrastructure required to write GPU drivers in Rust. While a great part of it was fueled by the development of Nova (the new driver for GSP-based NVIDIA GPUs), and by AGX (the driver for the GPUs on Apple's M-series chip that preceded Nova), a few components were being worked on to cater to a then undisclosed driver that was being prototyped behind the scenes. A driver that we now introduce to the community at large in a very early stage.

ChatGPT is testing a mysterious new feature called ‘study together’

In Brief Some ChatGPT subscribers are reporting a new feature appearing in their drop-down list of available tools called “Study Together.” The mode is apparently the chatbot’s way of becoming a better educational tool. Rather than providing answers to prompts, some say it asks more questions and requires the human to answer, like OpenAI’s answer to Google’s LearnLM. Some also wonder whether it will have a mode where more than one human can join the chat in a study group mode. OpenAI did not r

Adding a feature because ChatGPT incorrectly thinks it exists

Written by Adrian Holovaty on July 7, 2025 Well, here’s a weird one. At Soundslice, our sheet music scanner digitizes music from photographs, so you can listen, edit and practice. We continually improve the system, and I keep an eye on the error logs to see which images are getting poor results. In the last few months, I started noticing an odd type of upload in our error logs. Instead of images like this... ...we were starting to see images like this: Um, that’s just a screenshot of a Chat

How a big shift in training LLMs led to a capability explosion

In April 2023, a few weeks after the launch of GPT-4, the Internet went wild for two new software projects with the audacious names BabyAGI and AutoGPT. “Over the past week, developers around the world have begun building ‘autonomous agents’ that work with large language models (LLMs) such as OpenAI’s GPT-4 to solve complex problems,” Mark Sullivan wrote for Fast Company. “Autonomous agents can already perform tasks as varied as conducting web research, writing code, and creating to-do lists.”

ChatGPT is testing disruptive Study Together feature

OpenAI's "Study together" mode has been spotted in the wild, and it could help students prepare for exams directly from ChatGPT. We don't have the details yet, but references to ChatGPT Study Mode were first spotted in May, and testers noticed it widely earlier today. The Study together mode, which doesn't work right now, might allow students to either invite their friends to study on ChatGPT or have the AI act as a companion. We just don't know how it works yet, but it could disrupt the educ

OpenAI says GPT-5 will unify breakthroughs from different models

OpenAI has again confirmed that it will unify multiple models into one and create GPT-5, which is expected to ship sometime in the summer. ChatGPT currently has too many capable models for different tasks. While the models are powerful, it can be confusing because all models have identical names. But another issue is that OpenAI maintains an "o" lineup for reasoning capabilities, while the 4o and other models have multi-modality. With GPT-5, OpenAI plans to unify the breakthrough in its lineu

Bosses Are Using AI to Decide Who to Fire

Though most signs are telling us artificial intelligence isn't taking anyone's jobs, employers are still using the tech to justify layoffs, outsource work to the global South, and scare workers into submission. But that's not all — a growing number of employers are using AI not just as an excuse to downsize, but are giving it the final say in who gets axed. That's according to a survey of 1,342 managers by ResumeBuilder.com, which runs a blog dedicated to HR. Of those surveyed, 6 out of 10 admi
