The authors evaluated five synthetic pre-pretraining tasks across four model sizes, from 500 million to 7 billion parameters.
Synthetic warm-up training scales, but does not teach language grammar
Across models up to 7 billion parameters, synthetic pre-pretraining reduced subsequent training needs, with benefits linked more closely to long-range retrieval than grammatical competence.

Yamaguchi and colleagues tested whether pre-pretraining language models on synthetic, non-natural sequences remains useful at substantially larger scales and training budgets than previously studied.

In one line
Pre-pretraining with synthetic data improves token efficiency at scale, but gains come from long-range retrieval, not grammar.
