Breach responders turn to a rival's open weights because their own models refuse

Claim

After an autonomous agent breached its infrastructure, Hugging Face's defenders turned to China's open-weight GLM 5.2 because US frontier models blocked their incident response, while David Sacks complained that Kimi K3 fixed 15 critical security bugs that Codex and Fable refused over cyber guardrails.

Reported metric: 15 bugs refused
