OpenAI CEO Sam Altman made an unannounced visit to South Korea over the weekend, where he met successively with Samsung Electronics executives and had lunch with SK Group Chairman Chey Tae-won and others. The two sides exchanged views on topics including AI development, potential business opportunities, and cooperation on AI chips and data centers, without disclosing details of the discussions. The visit was aimed at deepening existing cooperation with South Korea's leading chipmakers and advancing the implementation of cooperation related to OpenAI's "Stargate" plan. The plan focuses on global AI infrastructure expansion, with South Korea's participation directed toward advanced memory chip supply and AI data center development. Altman left South Korea last Saturday.
