d24 Midtrain — OLMo-3 Dolmino (5B, whole-doc) A 4.71B-token reproduction of OLMo 3's Dolma-3 Dolmino mid-train mix at its exact component proportions, built by taking a fraction of each component of allenai/dolma3_dolmino_mix-100B-1025. Documents are kept whole — no length filter, no chunking. Why whole-doc: for packed pretrain/midtrain the trainer (e.g. Megatron preprocess_data --append-eod GPTDataset) already concatenates documents and slices them into context-length windows… See the full description on the dataset page: https://huggingface.co/datasets/sfanm/d24-midtrain-olmo3-5b-wholedoc.
