LLM emergent abilities may be metric artifacts, not model leaps

A recent analysis suggests that many observed "emergent abilities" in large language models might be artifacts of the evaluation metrics used, rather than genuine, abrupt shifts in model capabilities. Researchers propose that a smooth, underlying skill function drives model performance, but harsh, all-or-nothing metrics like exact-match can create the illusion of a sudden leap in ability as model scale increases. The study advocates for using continuous metrics alongside exact-match to provide a more accurate understanding of model scaling and to better anticipate new capabilities, especially for safety considerations.
