giffmana shared a striking training case: the culprit behind a loss spike could be traced to a single sentence (shown in the accompanying image), drawing praise from andrej-adjacent ML researchers like andrewncarr.
A single training sample triggering a loss spike is a rare but real phenomenon in LLM pretraining; such root-cause analyses offer useful insight into training stability.
