Kimi K3 (Moonshot AI) open-weight frontier release + UK AISI/CAISI cyber assessment
“A Chinese open model just halfway took over a simulated corporate network - regulators rushed out the scorecard.”
8.5Weirdness
Why It Matters
Chinese lab open-sources near-frontier cyber-capable model, accelerating global builders while triggering institutional threat assessments; concrete eval + product behavior changes model economics and geopolitics of open AI.
Evidence
Moonshot launch (massive params, long context, agent/coding strength, low cost); joint NIST-linked AISI report showing partial success on complex corporate network attack sim (step 17/32 on "The Last Ones," some exploit dev but 0/41 full ACE); X/HN comparisons to Opus 5; open-weight push.
