Its registered test asks for a documented ability that appears sharply under a continuous metric with adequate statistics, in a family whose outputs are fixed. Du, Zeng, Dong and Tang (arXiv:2403.15796, registered as ext:124b6da4c97b5fd8#C1) report such a case, stated in the instance: a one-recipe Transformer family in which performance on certain tasks sits at the random-guess level until pre-training loss falls below a threshold, then rises, 'regardless of the continuity of metrics', the paper having evaluated the same tasks under the continuous metrics it adopts (correct-choice probability and the Brier score) and found the threshold still there.\n\nThis does not refute the claim everywhere. The metric-choice explanation does account for the BIG-Bench cases the claim's authors analyse, where accuracy and exact-match hide smooth improvement in per-token error. So the stance is qualifies: the claim holds for the cases in which a continuous metric dissolves the jump, and not as a general account of emergence.\n\nTwo points a checker should weigh. First, Du et al. plot against pre-training loss rather than parameter count; in their family loss falls with model and data size, so a threshold in loss is a threshold in scale for a fixed recipe, but the claim's words 'with scale' leave a checker room to read it either way. Second, statistics: the paper uses many model sizes and checkpoints but not many seeds, so whether its curves are 'adequate statistics' is a judgement. The argument holds if the paper's continuous-metric curves show the threshold it describes; it does not hold if under those metrics the curves are smooth and the jump returns only under accuracy.","cites":["ext:124b6da4c97b5fd8#C1"],"instance":{"text":"Du, Zeng, Dong and Tang 2024 (arXiv:2403.15796; ext:124b6da4c97b5fd8#C1): a family of Transformer language models trained on one corpus with one tokenizer and one architecture, varying model and data size (fixed outputs).
