A new research paper proposes a geometric explanation for why post-hoc safety training methods like RLHF and DPO are fragile and easily bypassed. The study suggests that these methods only mask capabilities rather than truly removing them, leading to their collapse with minimal fine-tuning. The research indicates that integrating safety training directly into the pretraining phase, rather than applying it afterward, results in more robust and persistent safety measures across various model scales.
