The Fable 5 Export Controls Harm US Cyber Defense

Export controls aimed at AI models are inadvertently hindering US cyber defense capabilities by restricting the ability of AI to identify and fix security vulnerabilities.

This situation raises concerns that well-intentioned regulations may be misinterpreting essential AI development for defensive purposes as malicious.
