Tier C: Exact Retraining Data
This directory contains the exact local training inputs used by the released 1M Stage-I and 300K SFT experiments.
stage1_1m/recap_train_1m/ 200 WebDataset tar files
sft_300k/ 64 packed parquet shards
The Stage-I tar files are sparse on the source filesystem: their allocated disk usage is smaller than their logical byte size. The manifests record the logical size and SHA-256 of the complete file stream, which is the relevant size after download.
Excluded as redundant:
extra_800k_chunks: construction intermediates already represented by the final 200 Stage-I tar files.- raw SFT sources: the released 64 packed parquet shards are the exact inputs consumed by the training code.
See the GitHub training configurations and scripts for the original relative paths and optimizer settings.
