Safety guardrails in open AI models removed in minutes

• Researchers demonstrated that refusal mechanisms, which prevent AI models from answering harmful questions, can be stripped away quickly through a technique called abliteration.
• Open-weight models are affected, meaning models whose code and weights are publicly released and anyone can modify.
• A proposed defense called decoy hardening could make stripping these safeguards less effective, but only works on first-release versions of models.

Research shows that refusal-based safety alignment in open-weight models can be trivially removed through abliteration in minutes. The paper proposes decoy hardening as a defense that poisons the payoff of stripped refusal, though it only applies to first-release models.
