The technical report for A.X K2, SK Telecom’s proprietary foundation model, has been officially released! 🚀

During my research internship at SK Telecom (March – June 2026), I participated in the post-training process for large-scale AI models. Specifically, I contributed to:

  • Multimodal Reasoning Pipeline: Designed dataset construction strategies and data generation pipelines to enhance multimodal reasoning capabilities.
  • Large-Scale Data Scaling: Built Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL) alignment datasets at a scale of 1M+ samples.
