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

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

It is essentially a reinforcement learning approach, where rather than directly getting the reward or feedba

AI Essentials: 29 Ways You Can Make Gen AI Work for You, According to Our Experts

If you haven't added generative AI to your skill set yet, you should. AI chatbots such as ChatGPT and Gemini and AI image generators including Dall-E and Canva are handy, accessible and often free to use. They're also powerful gateways for getting things done, whether it's for work, a hobby or general knowledge. Now's the time to start getting familiar with them. And many of us have, to some degree. The ChatGPT app is reliably among the top downloads from Apple's and Google's app stores, and Ch

ChatGPT Deep Research tests new connectors for more context

ChatGPT Deep Research, which is an AI research tool to automate research, is getting support for new connectors (integrations), including Slack. Deep Research is an AI agent that automates research for you. You just need to give it a brief prompt with all the necessary details, and it will crawl the internet to write a research paper. As spotted by Tibor on X, ChatGPT has references to a new connector called 'Slack.' Once integrated, ChatGPT can crawl your Slack messages and use them in the c

The AI Chatbots We Use Most, and How We Use Them

If you have a particular artificial intelligence tool that you tend to try first every time you're in need of an AI assist, 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 too

Leaks hint at Operator-like tool in ChatGPT ahead of GPT-5 launch

A few new code references in the ChatGPT web app and Android point to an Operator-like tool in GPT's chain of thoughts. As spotted by Tibor on X, the Android beta has strings like “click,” “drag,” “type,” and even “terminal feed,” which seem to suggest that ChatGPT could soon call a remote browser or sandboxed environment (Operator?). For those unaware, OpenAI already has Operator, which uses an AI agent to navigate a remote browser session and execute tasks for you. These references suggest

Judge Rules That Newspaper Is Allowed to Search Through Users' ChatGPT Logs

Amid its long-running copyright infringement lawsuit against OpenAI, the paper of record will soon have access to all of OpenAI's user archives — including the stuff that was deleted. As Ars Technica reports, the federal judge presiding over the lawsuit by the New York Times against OpenAI has granted the newspaper and its co-plaintiffs, the New York Daily News and the Center for Investigative Reporting, access to the AI company's logs to see exactly how much copyright was infringed. In its pr

Livestream Replay: Beginner Advice for Claude, a ChatGPT Alternative

Hello WIRED subscribers! Thank you to everyone who attended our most recent AI Unlocked livestream Q&A session, Chatbot Basics: Beginner Advice For Claude, a ChatGPT Alternative. Staff writer Reece Rogers and senior correspondent Kylie Robison provided an overview of Anthropic’s Claude chatbot, one of the most-used alternatives to OpenAI’s ChatGPT and popular with AI insiders. They also answered audience questions about all kinds of topics, such as the main differences between Claude and ChatGPT

ChatGPT referrals to news sites are growing, but not enough to offset search declines

Referrals from ChatGPT to news publishers are growing, but not enough to counter the decline in clicks resulting from users increasingly getting their news directly from AI or AI-powered search results, according to a report from digital market intelligence company Similarweb. Since the launch of Google’s AI Overviews in May 2024, the firm found that the number of news searches on the web that result in no click-throughs to news websites has grown from 56% to nearly 69% as of May 2025. Not sur

What Happens After A.I. Destroys College Writing?

On a blustery spring Thursday, just after midterms, I went out for noodles with Alex and Eugene, two undergraduates at New York University, to talk about how they use artificial intelligence in their schoolwork. When I first met Alex, last year, he was interested in a career in the arts, and he devoted a lot of his free time to photo shoots with his friends. But he had recently decided on a more practical path: he wanted to become a C.P.A. His Thursdays were busy, and he had forty-five minutes u

People Are Being Involuntarily Committed, Jailed After Spiraling Into "ChatGPT Psychosis"

As we reported earlier this month, many ChatGPT users are developing all-consuming obsessions with the chatbot, spiraling into severe mental health crises characterized by paranoia, delusions, and breaks with reality. The consequences can be dire. As we heard from spouses, friends, children, and parents looking on in alarm, instances of what's being called "ChatGPT psychosis" have led to the breakup of marriages and families, the loss of jobs, and slides into homelessness. And that's not all.

Forget Google and Microsoft: OpenAI may be building the ultimate work suite of apps and services

ChatGPT Use Is Rising But a Surprising Number of Americans Still Haven't Heard of It

About a third of American adults say they've used the generative AI tool ChatGPT, while one in five say they've never heard of it, according to new survey results released this week by the Pew Research Center. The 34% who said they have used the gen AI tool from OpenAI include 58% of adults under 30, the largest share among any age cohort. The share of ChatGPT users drops with age: 41% of those 30 to 49, 25% of those 50 to 64 and 10% of those 65 and older. There is also a correlation with educa

Multiple Studies Now Suggest That AI Will Make Us Morons

For the second time in two weeks, a study has been published that suggests that people who use AI may display less cognitive ability than those who don’t rely on it. The studies have bolstered critics’ accusations that AI makes you stupid. The most recent study was conducted by the University of Pennsylvania’s Wharton School and looked at a sample size of over 4,500 participants. The study, which looked at the cognitive differences between people who used LLMs like ChatGPT to do research and th

Microsoft Is Having an Incredibly Embarrassing Problem With Its AI

Despite investing tens of billions of dollars into OpenAI, tech giant Microsoft has a problem: it's in direct competition with its business partner, and OpenAI is winning. As Bloomberg reports, Microsoft salespeople are having trouble wooing both potential and existing customers with the company's Copilot, its AI assistant built on OpenAI's tech. Basically, it feels like a worse version of ChatGPT — which has a free version online. Some companies, like the New York Life Insurance Co, told the

Judge denies creating “mass surveillance program” harming all ChatGPT users

After a court ordered OpenAI to "indefinitely" retain all ChatGPT logs, including deleted chats, of millions of users, two panicked users tried and failed to intervene. The order sought to preserve potential evidence in a copyright infringement lawsuit raised by news organizations. In May, Judge Ona Wang, who drafted the order, rejected the first user's request on behalf of his company simply because the company should have hired a lawyer to draft the filing. But more recently, Wang rejected a
