Xekrung 1.5 27B Preview explained: what's verified, what isn't
Alibaba Security AGI Lab's cybersecurity fine-tune holds the top row of CyberGym's model leaderboard. The weights are not released, the launch post does not exist, and most of what circulates traces back to one lab writeup. Xekrung 1.5 27B Preview, written as XekRung-1.5-27B-Preview on the leaderboard, is a cybersecurity-specialized version of Alibaba's Qwen3.8-27B, and it holds the number one spot on CyberGym's model leaderboard with an 88.9% success rate.
