Amazon’s cloud-computing arm plans to invest an additional $5 billion in South Korea over the next six years to build new artificial-intelligence data centers in the country.

Billionaire Bill Ackman, a hedge fund manager who wants build a modern-day Berkshire Hathaway, has been buying stock in Amazon and Uber.

Amazon said it has completed its Project Rainier data-center cluster, which is powered by nearly 500,000 of the company’s Trainium 2 chips.

Amazon.com said on Wednesday it has launched its compute cluster project called Rainier, and added that artificial intelligence firm Anthropic will use more than a million chips of the infrastructure by the end of the year.

Amazon will cut about 14,000 corporate jobs as the online retail giant ramps up spending on artificial intelligence while cutting costs elsewhere.

Amazon said it will cut approximately 14,000 white-collar jobs, representing about 4% of the total corporate workforce, as it seeks to gain efficiencies — and as it prepares for advances in artificial intelligence that will reduce the need for humans to run the company.
