🇰🇷🪖 South Korea was briefly under martial law amid a political dispute. President Yoon Suk Yeol late Tuesday declared martial law, a move that suspends democratic processes, accusing his opposing political party – which controls parliament – of threatening the country’s constitutional order and sympathizing with North Korea. Less than three hours later, South Korea’s parliament voted 190-0 to lift the martial law declaration, which was denounced by both the opposition and the leader of Yoon’s own party. South Korea’s military eventually stood down a few hours afterward, when President Yoon said he would lift his martial law order in response to parliament’s vote.

💻 Amazon Web Services is taking aim at Nvidia’s chip dominance. Amazon’s cloud computing arm yesterday announced plans for “Ultracluster,” a massive AI supercomputer featuring hundreds of thousands of its homegrown Trainium chips that will be used by Anthropic to train AI models. AWS also announced a new massive server (Ultraserver) and unveiled Apple as a chip customer. Together, experts say these moves signal Amazon’s commitment to its Trainium chips as a low-cost, yet capable option compared to Nvidia’s massively popular graphics processing units (GPUs), which currently hold ~95% market share. Fellow cloud competitors Microsoft and Google are also building their own AI chips in a bid to reduce reliance on Nvidia.

🚗 Jaguar unveiled its first concept car since rebranding. The Type 00 model won’t go into production for sale to the public since it’s a concept car. But it gives a hint at the new direction of the historic automaker, which has seen falling sales and is losing money on every car sold. Jaguar’s rebrand – which, after revealed, Chief Creative Officer Gerry McGovern told journalists: “[We have] not been sniffing the white stuff, this is real” – involves axing its entire product line and rebooting itself as a luxury EV-only company competing with the likes of Bentley and Porsche. The rebrand has divided opinion, but, per Jaguar, that’s exactly what it’s designed to do.
