The artificial intelligence startup Perplexity AI has raised tens of millions of dollars from the likes of Jeff Bezos and other prominent tech investors for its mission to rival Google in the business of searching for information.

But its AI-driven search chatbot is already facing challenges as some news media companies object to its business practices and tech giants Google, and now Apple, are increasingly fusing similar AI features into their core products.

Social media platform X is now hiding your likes.

In an update posted on the platform formerly known as Twitter earlier this week, X's engineering team said it would be "making Likes private for everyone to better protect your privacy." That means that users will still be able to see their own likes, but others will not — putting an end to a feature that many had long used.

Apple has jumped into the race to bring generative artificial intelligence to the masses, spotlighting a slew of features Monday designed to soup up the iPhone, iPad and Mac.

And in a move befitting a company known for its marketing prowess, the AI technology coming as part of free software updates later this year is being billed as "Apple Intelligence."

Donald Trump has joined the popular video-sharing app TikTok, a platform he once tried to ban while in the White House, and posted from a UFC fight two days after he became the first former president and presumptive major party nominee in U.S. history to be found guilty on felony charges.

"It's an honor," Trump said in the TikTok video, which features footage of him waving to fans and posing for selfies at the Ultimate Fighting Championship fight in Newark, New Jersey, on Saturday night. The video ends with Trump telling the camera: "That was a good walk-on, right?"

Disruptive digital attacks, many linked to Russian-backed groups, have doubled in the European Union in recent months and are also targeting election-related services, according to the EU's top cybersecurity official.

Juhan Lepassaar, head of the European Union Agency for Cybersecurity, or ENISA, told The Associated Press in an interview that attacks with geopolitical motives have steadily risen since Russia's full-scale invasion of Ukraine on Feb. 24, 2022.

OpenAI on Monday said it plans to halt the use of one of its ChatGPT voices that "Her" actor Scarlett Johansson says sounds "eerily similar" to her own.

In a post on the social media platform X, OpenAI said it is "working to pause" Sky — the name of one of five voices that ChatGPT users can chose to speak with. The company said it had "heard questions" about how it selects the lifelike audio options available for its flagship artificial intelligence chatbot, particularly Sky, and wanted to address them.

World leaders are expected to adopt a new agreement on artificial intelligence when they gather virtually Tuesday to discuss AI's potential risks but also ways to promote its benefits and innovation.

The AI Seoul Summit is a follow-up to November's inaugural AI Safety Summit at Bletchley Park in the United Kingdom, where participating countries agreed to work together to contain the potentially "catastrophic" risks posed by galloping advances in AI.

The European Union opened fresh investigations Thursday into Facebook and Instagram over suspicions that they're failing to protect children online, in violation of the bloc's strict digital regulations for social media platforms.

It's the latest round of scrutiny for parent company Meta Platforms under the 27-nation EU's Digital Services Act, a sweeping set of regulations that took effect last year with the goal of cleaning up online platforms and protecting internet users.

Some social media users are calling out celebrities for what they say is inaction in the face of a humanitarian crisis in Gaza — and they've taken to a "blockout" to pressure the stars to take a stand.

For the blockout, users put a block on seeing any and all content from the accounts of certain celebrities on social media platforms including X, TikTok and Instagram. Some have posted about the celebrities they've blocked, using a hashtag such as #blockout, #blockout2024, or #celebrityblockout, while others have shared posts from users lambasting attendees of high-glamour events like the Met Gala and contrasting it with the situation in Gaza.

A newly released ad promoting Apple's new iPad Pro has struck quite a nerve online.

The ad, which was released by the tech giant Tuesday, shows a hydraulic press crushing just about every creative instrument artists and consumers have used over the years — from a piano and record player, to piles of paint, books, cameras and relics of arcade games. Resulting from the destruction? A pristine new iPad Pro.
