Small language models fail to follow conflicting instructions, study finds

A new research paper explores the distinction between task competence and instruction following in small language models. The study found that while models generally improve in both areas with scale, smaller models often ignore conflicting instructions, maintaining task accuracy but failing to adhere to user requests. This suggests that increased task capability does not automatically translate to reliable control over model behavior, and standard accuracy metrics can mask instruction-following failures. AI

IMPACT Highlights the need for better evaluation metrics beyond standard accuracy to ensure reliable control over LLM behavior.

    Task Competence Is Not Instruction Following: Evaluating Instruction-Conflicting Behavior in Small Language Models

    arXiv:2607.19608v1 Announce Type: new Abstract: Instruction tuning is meant to make language models follow user requests, yet it is unclear whether small models comply when an instruction conflicts with their usual task behavior. We study this across three tasks - multiple-choice…
