Apple has temporarily disabled Apple Intelligence summaries for news apps for users of its beta software in a sign of the challenges the company is dealing with in its AI technology.
The decision to pause AI summaries comes weeks after the BBC highlighted that Apple’s AI system had twisted its news notifications to display inaccurate facts. The pause only affects people using Apple’s beta software, not those using the company’s main operating systems.
News and entertainment apps, such as The New York Times, began showing a short message inside the iPhone settings app on Thursday noting that AI-powered summaries were “temporarily unavailable.”
The pause on one of Apple Intelligence’s core features highlights the challenge Apple faces in the roll out of its artificial intelligence technology, which has been scrutinized by many users on social media.
“With the latest beta software releases of iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3, Notification summaries for the News & Entertainment category will be temporarily unavailable,” an Apple representative told CNBC in a statement.
The spokesperson noted that Apple is working on improvements to the software that are coming in a future software update. The company did not say when it will roll out its iOS 18.3 software to users of the main version of the iPhone operating system, but it could take weeks, based on Apple’s previous software release patterns.
The decision to temporarily pause the AI summaries comes on the same day that Apple saw its stock close down 4%, marking its worst day of trading since Aug. 5. A reason for the drop was due to notable Apple supply chain analyst Ming-Chi Kuo writing on Monday that the Apple Intelligence suite of features does not appear to be boosting iPhone sales.
Apple Intelligence struggles since launch
The company launched Apple Intelligence in October as the signature feature in its latest line of iPhone models and its answer to Silicon Valley’s AI arms race that kicked off with the launch of OpenAI’s ChatGPT in late 2022.
Apple has used the AI features as the key selling point in its advertisements and marketing for its latest hardware products, but the software has been riddled with issues.
The company says that the entire Apple Intelligence system is in beta, and the update on Thursday added language to say that the AI software can produce unexpected results.
Apple Intelligence includes several features, including image generators, but the one that’s received the most attention is how it can summarize entire stacks of notifications into concise sentences — useful, according to Apple’s marketing materials, for getting through hundreds of group chat notifications without scrolling through the whole discussion.
With the Thursday update, Apple said it will show any AI-summarized notification in italics to distinguish them from other notifications.
In testing, Apple Intelligence summaries weren’t perfect, but the errors were mostly funny and obvious. Problems cropped up when the technology began being used to summarize news, and it displayed false information.
The most egregious well-documented error happened in December, when 22 separate BBC news notifications were combined into a three-part headline that started with “Luigi Mangione shoots himself.” The alleged Brian Thompson assassin has not done that.
The feature also combined headlines from The New York Times into a November notification that falsely said that Israeli Prime minister Benjamin Netanyahu had been arrested, according to a ProPublica reporter’s post on social media.
Another Apple Intelligence notification on Jan. 3 said that darts player Luke Littler had won a world championship, which had yet to take place, according to the BBC. The technology also conflated notifications from BBC’s sports app to say that “Brazilian tennis player, Rafael Nadal, comes out as gay.” Nadal is Spanish and is married to Maria Francisca Perello.
Apple on Thursday also rolled out a new feature that lets users turn off AI summaries for any app by swiping left on the notification from the phone’s lock screen. Users previously could only turn off AI summaries through the settings app.
The letters AI, which stands for “artificial intelligence,” stand at the Amazon Web Services booth at the Hannover Messe industrial trade fair in Hannover, Germany, on March 31, 2025.
Amazon said Wednesday that its cloud division has developed hardware to cool down next-generation Nvidia graphics processing units that are used for artificial intelligence workloads.
Nvidia’s GPUs, which have powered the generative AI boom, require massive amounts of energy. That means companies using the processors need additional equipment to cool them down.
Amazon considered erecting data centers that could accommodate widespread liquid cooling to make the most of these power-hungry Nvidia GPUs. But that process would have taken too long, and commercially available equipment wouldn’t have worked, Dave Brown, vice president of compute and machine learning services at Amazon Web Services, said in a video posted to YouTube.
“They would take up too much data center floor space or increase water usage substantially,” Brown said. “And while some of these solutions could work for lower volumes at other providers, they simply wouldn’t be enough liquid-cooling capacity to support our scale.”
Rather, Amazon engineers conceived of the In-Row Heat Exchanger, or IRHX, that can be plugged into existing and new data centers. More traditional air cooling was sufficient for previous generations of Nvidia chips.
Customers can now access the AWS service as computing instances that go by the name P6e, Brown wrote in a blog post. The new systems accompany Nvidia’s design for dense computing power. Nvidia’s GB200 NVL72 packs a single rack with 72 Nvidia Blackwell GPUs that are wired together to train and run large AI models.
Computing clusters based on Nvidia’s GB200 NVL72 have previously been available through Microsoft or CoreWeave. AWS is the world’s largest supplier of cloud infrastructure.
Amazon has rolled out its own infrastructure hardware in the past. The company has custom chips for general-purpose computing and for AI, and designed its own storage servers and networking routers. In running homegrown hardware, Amazon depends less on third-party suppliers, which can benefit the company’s bottom line. In the first quarter, AWS delivered the widest operating margin since at least 2014, and the unit is responsible for most of Amazon’s net income.
Microsoft, the second largest cloud provider, has followed Amazon’s lead and made strides in chip development. In 2023, the company designed its own systems called Sidekicks to cool the Maia AI chips it developed.

Bitcoin hit a fresh record on Wednesday afternoon as an Nvidia-led rally in equities helped push the price of the cryptocurrency higher into the stock market close.
The price of bitcoin was last up 1.9%, trading at $110,947.49, according to Coin Metrics. Just before 4:00 p.m. ET, it hit a high of $112,052.24, surpassing its May 22 record of $111,999.
The flagship cryptocurrency has been trading in a tight range for several weeks despite billions of dollars flowing into bitcoin exchange traded funds. Bitcoin purchases by public companies outpaced ETF inflows in the second quarter. Still, bitcoin is up just 2% in the past month.

Bitcoin climbs above $112,000
On Wednesday, tech stocks rallied as Nvidia became the first company to briefly touch $4 trillion in market capitalization. In the same session, investors appeared to shrug off the latest tariff developments from President Donald Trump. The tech-heavy Nasdaq Composite notched a record close.
While institutions broadly have embraced bitcoin’s “digital gold” narrative, it is still a risk asset that rises and falls alongside stocks depending on what’s driving investor sentiment. When the market is in risk-on mode and investors buy growth-oriented assets like tech stocks, bitcoin and crypto tend to rally with them.
Investors have been expecting bitcoin to reach new records in the second half of the year as corporate treasuries accelerate their bitcoin buying sprees and Congress gets closer to passing crypto legislation.

Perplexity AI on Wednesday launched a new artificial intelligence-powered web browser called Comet in the startup’s latest effort to compete in the consumer internet market against companies like Google and Microsoft.
Comet will allow users to connect with enterprise applications like Slack and ask complex questions via voice and text, according to a brief demo video Perplexity released on Wednesday.
The browser is available to Perplexity Max subscribers, and the company said invite-only access will roll out to a waitlist over the summer. Perplexity Max costs users $200 per month.
“We built Comet to let the internet do what it has been begging to do: to amplify our intelligence,” Perplexity wrote in a blog post on Wednesday.
Perplexity is best known for its AI-powered search engine that gives users simple answers to questions and links out to the original source material on the web. After the company was accused of plagiarizing content from media outlets, it launched a revenue-sharing model with publishers last year.
In May, Perplexity was in late-stage talks to raise $500 million at a $14 billion valuation, a source familiar confirmed to CNBC. The startup was also approached by Meta earlier this year about a potential acquisition, but the companies did not finalize a deal.
“We will continue to launch new features and functionality for Comet, improve experiences based on your feedback, and focus relentlessly–as we always have–on building accurate and trustworthy AI that fuels human curiosity,” Perplexity said Wednesday.
