Mixed Pretraining Dataset

Auto-generated mixed dataset created by streaming, token-estimating, and interleaving multiple Hugging Face datasets according to specified token proportions.

Dataset Summary

Metric	Value
Total estimated tokens	10,000,000,000
Total rows	8,896,601
Parquet shards	40
Token estimator	`Qwen/Qwen2.5-0.5B`
Generated at	2026-08-19 22:09 UTC

Token counts are estimates produced by the tokenizer listed above. Actual counts with your training tokenizer may vary.

Source Breakdown

Source	Est. Tokens	Examples	Proportion
`wikimedia/wikipedia#20231101.en@train`	1,000,000,000	1,220,505	10.0%
`openbmb/Ultra-FineWeb@en`	4,000,000,000	4,804,170	40.0%

`HuggingFaceCode/stack-v3-train@train::expand_stack_v3`	2,000,000,000	1,435,550	20.0%

Dataset Structure

text: raw text content.
source: source dataset identifier.
estimated_tokens: estimated token count for the row.

How to Use

from datasets import load_dataset

ds = load_dataset("Cion-lab/Pretraining-10B-v1", split="train", streaming=True)

for row in ds:
    print(row["text"][:200])
    break

Generation Notes

Datasets were streamed to avoid downloading full corpora.
Rows were interleaved by token-budget deficit instead of concatenating datasets.
Sources were repeated/cycled automatically when needed to fill budgets.
Generation state was saved to state.json for resumability.
