LoRA fine-tuning unexpectedly alters model behavior, not just specific word avoidance

Researchers explored how LoRA adapters influence large language models, discovering that while they can alter specific behaviors like text length, they struggle to enforce negative constraints such as avoiding certain words. This suggests that LoRA fine-tuning is more effective at teaching new behaviors than at imposing strict prohibitions. AI

IMPACT Fine-tuning methods like LoRA may be better suited for teaching new capabilities than for enforcing strict content restrictions.
