d24 Midtrain — OLMo-3 Dolmino subsample A length-filtered (≤2048 GPT-2 tokens) subsample of OLMo 3's Dolma-3 Dolmino mid-train mix, used for the d24 v1base-olmo3 midtrain. Built by taking a uniform fraction of each component of allenai/dolma3_dolmino_mix-100B-1025 (so the mix proportions are preserved), then dropping documents >2048 tokens — which naturally shrinks the long-doc components (reasoning traces, olmOCR PDFs) that don't fit the 2048 context. 5,902,548 documents… See the full description on the dataset page: https://huggingface.co/datasets/sfanm/d24-midtrain-olmo3.
