+This organisation hosts **LittleCurriculum**, the K–5-filtered pretraining dataset, as well as the paired **LittleLearner** (K–5-filtered) and
 **Unfiltered** (baseline general corpus) checkpoints at three sizes, plus
 matched post-trained variants. All checkpoints share the same architecture
 and tokenizer, so a LittleLearner *X* B and Unfiltered *X* B differ only in
 what data they saw during pretraining — the controlled comparison the paper
 is built around.
