The UNSPECIFIC framework, developed by researchers at the University of Massachusetts, Amherst, generates more natural and challenging instruction-following benchmarks for large language models by synthesizing generalized constraints from multiple sources and iteratively refining them. It introduces a "core satisfaction rate" metric that evaluates constraint adherence after article summarization, revealing that models often exhibit superficial instruction following, with core satisfaction rates significantly lower than original rates.

Key insights

  • The "core satisfaction rate" metric, derived from evaluating constraints on summarized text, effectively distinguishes superficial from deep instruction following in LLMs.
  • Synthesizing constraints that are common to multiple similar articles, combined with selective revision, creates more natural and challenging benchmarks, mitigating copy-and-paste behavior.
  • LLMs exhibit varied levels of superficial instruction following across different domains (e.g., news vs. blogs) and task types (generation vs. editing), and this behavior is influenced by model scaling.
