Apple has rolled out its next generation of iPhones that includes a new ultrathin model and a slight price hike for one of its high-end models, while the company feels the squeeze of a global trade war. The iPhone 17 line-up includes a new slimmed-down model that will adopt the "Air" name that Apple already uses for its sleekest iPads and Mac computers. The new iPhones are the first to be released since President Donald Trump returned to the White House and unleashed a barrage of tariffs, in what his administration says is an attempt to bring overseas manufacturing back to the U.S. — a crusade that has thrust Cook into the hot seat.

Apple on Monday charged into the artificial intelligence craze with a new iPhone lineup that marks the company's latest attempt to latch on a technology trend and transform it into a cultural phenomenon. The four different iPhone 16 models will all come equipped with a special chip needed to power an AI suite that Apple is hoping will reverse a recent slump sales. Among other things, Apple's AI features are designed to turn its often-blundering virtual assistant Siri into a smarter and more versatile sidekick. But the changes won't be available when the new iPhones hit the store September 20. Instead, they will come out in December as part of a free software update.

Tech giant Nvidia is now worth over $3.2 trillion, with its dominance as a chipmaker making it the poster child of the artificial intelligence boom. After the stock's swift rise on Wall Street it briefly topped Microsoft as the most valuable company in the S&P 500 this week. And it's an unlikely piece of technology — graphics chips initially invented to create more realistic video games — that has propelled the company to AI fame.

Apple jumped into the race to bring generative artificial intelligence to the masses during its World Wide Developers Conference Monday that spotlighted an onslaught of features designed to soup up the iPhone, iPad and Mac. Even as it tried to put its own stamp on the hottest area of technology, Apple tacitly acknowledged it needed help to catch up with companies like Microsoft and Google, who have emerged as the early leaders in the AI field. Apple is leaning on ChatGPT, made by the San Francisco startup OpenAI, to help make its often-bumbling virtual assistant Siri smarter and more helpful.
