BAAI/OpenSeek-Pretrain-100B

OpenSeek Pretraining Dataset v1.0

We have released a portion of the sampled 100B tokens data from the CCI4.0-M2 v1, including Chinese and English Web datasets, domain-specific datasets and Chain-of-Thought reasoning datasets.

The dataset directory is consistent with the overall dataset. For a detailed description of the dataset, please refer to CCI4.0-M2 v1 README.
