multilingual-macaroni-models

All 24 models from our BabyLM 2026 Multilingual-track study of code-switched pretraining curricula (English / Dutch / Chinese): 8 training conditions × 3 seeds (42/43/44), each a 12-layer GPT-2 (~98M params, 16k vocab, 1024 context) trained from scratch on the 100M byte-premium-adjusted-word budget.

Every model lives on its own branch (revision). The main branch holds only this card.

Condition (branch)	Trained on	Description
switch	switch corpus	Full mixed code-switching, shuffled ordering
noswitch	noswitch	Monolingual twin
word	word	Intrasentential (word-level) CS only
sent	sent	Sentence-level CS only
par	par	Parallel CS
salad	salad	Word-salad control
curriculum	curriculum	Staged CS curriculum (intra → sentence → mono) — the leaderboard submission
curriculum_noswitch	curriculum_noswitch	Monolingual twin, staged

Seeds: branch <condition> = seed 42; <condition>-s43, <condition>-s44 = seeds 43, 44.

Training data: drooryck/multilingual-macaroni-corpus. The curriculum (CS) model is the same weights as the leaderboard submission drooryck/babylm-macaroni, which additionally carries the 28 chck_*M learning-curve revisions.
