arXiv:2606.29858v1 Announce Type: new Abstract: Language model loss follows remarkably regular scaling laws over model and data size, yet it remains unclear why the aggregate loss should exhibit a power-law form. Existing explanations often attribute this regularity to a heavy-tailed spectrum of pattern difficulty in natural language, but this view has not been directly validated at token-level granularity in large-scale real-data training. We present a token-level framework that decomposes scaling laws into localized learning events of individual contextualized tokens. By fitting token loss t
This research provides a novel token-level framework for understanding language model scaling laws, offering a deeper mechanistic insight into AI learning processes that has been previously unvalidated.
A more granular understanding of how language models learn could accelerate AI development, leading to more efficient training, better model performance, and a clearer path to advanced AI capabilities.
The conventional view of smooth, power-law scaling in language model loss is refined by revealing hidden stepwise learning at the token level, suggesting a more complex underlying mechanism.
