# all-wikis-mix FineWeb-style Parquet shards created by merging all the already-built monolingual Wikipedia datasets into a **single dataset**. ## Why this exists Training pipelines that round-robin by shard can “loop” on tiny datasets (repeating the same few shards). A single merged dataset has a healthier shard count and makes mixing more stable. ## What’s inside - **Format**: `nanochat-parquet-v1` - **Layout**: `shard_*.parquet` + `metadata.json` - **Text column**: `text` - **Parquet settings**: zstd (level 3), `row_group_size=1024`, `use_dictionary=False`, `write_statistics=False` ## Loading ```python from datasets import load_dataset ds = load_dataset("JayJayThrowThrow/all-wikis-mix", split="train") print(ds.column_names) # ["text"] ```
