Moonshot says it cut Kimi K3.1 Pro’s cyber score before open-weight release

Moonshot has released Kimi K3.1 Pro in its apps and API, with full model weights due by 4 November. The Chinese AI company says it removed cyber-related training data: on its unpublished in-house exploit test, the released model scored 81%, against 90.5% for an unfiltered version; Reuters reports the figures have not been independently verified.

Bottom line — The 81% result is Moonshot’s own; outsiders will be able to examine the weights after their planned 4 November release.
