Researchers have developed a new alignment defense called VaccineBooster, which combines embedding perturbation and gradient attenuation to protect language models from harmful fine-tuning attacks. In tests on LLaMA-2 7B, this hybrid approach achieved a lower OpenAI moderation score than existing methods. However, a variant focusing solely on gradient attenuation maintained a higher refusal rate for harmful content, suggesting a trade-off between reducing flagged content and preserving explicit refusal behavior.

IMPACT Offers practical guidance for prioritizing content safety or refusal retention in aligned models exposed to untrusted fine-tuning data.
