SK Group Chairman Chey Tae-won has met with the heads of leading U.S. tech firms, including Nvidia, Google LLC and Microsoft, to discuss business ties in the artificial intelligence (AI) sector, SK hynix said Friday. According to the Korean chipmaker, Chey met with Nvidia Chief Executive Officer (CEO) Jensen Huang on Thursday last week (U.S. time) in Silicon Valley to discuss potential AI collaborations. "The partnership, which began during the early stages of HBM development amid market uncertainty, has evolved into a strategic relationship that extends beyond supply to joint product planning," SK hynix said in a release. "SK hynix aims to expand its collaboration with Nvidia from AI chips to broader AI infrastructure," it added. On Tuesday, Chey also met with Microsoft CEO Satya Nadella in Seattle to discuss cooperation in high bandwidth memory (HBM) along with AI data centers and solutions. "The meeting reflects SK Group's strategy to strengthen its position in the global AI ecosystem by broadening cooperation with Microsoft beyond semiconductors into AI infrastructure and services," t
