# Dataset

Mixed pretraining dataset built from:

| Source | Weight | Notes |
|--------|--------|-------|
| epfml/FineWeb-HQ | 60% | Quality-filtered web text (score > 0.8) |
| HuggingFaceTB/cosmopedia | 20% | Sequential: stanford → wikihow → web_samples_v2 |
| HuggingFaceTB/finemath (finemath-4plus) | 10% | Mathematical reasoning |
| bigcode/python-stack-v1-functions-filtered | 10% | Python code functions |

**Total rows:** 6,000,000  
**Shards:** 60 parquet files  
**Split:** all rows are in `train`
