New CD scaling laws bridge compute and data limits in LLM pretraining

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced new scaling laws called Compute-Data (CD) scaling laws, which offer a unified framework for pretraining large language models. These laws bridge the gap between compute-optimal scaling, where data is abundant, and data-optimal scaling, where the dataset is fixed. The framework incorporates a token-effectiveness function that quantifies the value of derived tokens relative to fresh ones, considering factors like multi-epoch repetition and paraphrasing. This function reveals that token effectiveness is not constant but depends on model size, the ratio of tokens to parameters, and the amount of derived data, suggesting that classical compute-optimal allocation is suboptimal in most practical scenarios.

    Bridging Compute- and Data-Optimal Pretraining

    arXiv:2607.25271v1 Announce Type: cross Abstract: Classical compute-optimal scaling laws assume an unbounded supply of fresh pretraining data, yet pretraining is increasingly entering a regime in which compute grows faster than the availability of high-quality data. We propose Co…
