SKT says A.X K2 evolves from answering AI to working AI

SK Telecom is targeting the industrial AI market with its proprietary foundation model A.X K2, which it says has evolved into a “working AI” that understands long context and uses external tools to carry out tasks. The company says the model has 688 billion parameters and shows improved performance across benchmarks, while keeping active parameters at 33 billion during inference to control computing costs. SKT is also developing multimodal and security-focused deployments and will release weights and inference code under an Apache 2.0 licence.
