Might be useful to those who have not been in the space but this is old news. 2020.

I tried to find out how many "tokens" (I know: depends on the tokenizer) "The Pile" has but couldn't find it.

As far as I understand RedPajama has 1.2T (https://github.com/togethercomputer/RedPajama-Data) and has a table in the readme listing the main parts and how many tokens each part has.

I wrote an article about recent data pipelines as well if anyone is interested: https://blog.christianperone.com/2023/06/appreciating-llms-d...

Arguably “The Pile” approach is the bane of open source and small player LLMs. Because the models are shaped by data. And there is little beauty in “The Pile”.
