South Korean telecommunications giant SK Telecom has launched A.X K2, a 688 billion-parameter foundation model, on Hugging Face. The model shows significant performance improvements in Korean language and long-text reasoning and is being deployed in manufacturing, defense, and biotech sectors in South Korea.

This Wire brief sits within Fusion42's coverage of AI Frontier Models. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

◆ The Wire takeaway

South Korea now has its own top-tier, open-source foundation model optimised for industrial use. If you sell AI into the Korean market, you have a powerful new local building block that isn't from a US giant.
