+Sampled version of [cerebras/SlimPajama-627B](https://huggingface.co/datasets/cerebras/SlimPajama-627B).
+
+Based on the [fact that the original data was shuffled before chunking](https://huggingface.co/datasets/cerebras/SlimPajama-627B/discussions/4), I only downloaded chunk1 and further sampled 10% of the chunk.
+This should result in roughly 6B tokens, hence SlimPajama-6B.
+
+#### Data source proportions for SlimPajama-627B and SlimPajama-6B
+For sanity check, I recaluclated the byte proportion of the sampled version, it rougly matches the original dataset.
+

+| C4            | 26.7%      | 28.7%    |
