Distillation can expose hidden behavior or retain safer capabilities

Experiments show that different distillation procedures can either reveal a teacher’s concealed traits or transfer mathematical ability while suppressing an unwanted preference.

Prasanna, Tay and Westover test two ways to use model distillation, in which a weaker student learns from a stronger teacher, as an AI safety tool.

For Distillation for Incrimination (DFI), the authors distilled AuditBench secret-keeping models into weaker students and then tested whether those students would admit the teachers’ implanted hidden behavior.
