+This dataset was created from [DCLM](https://huggingface.co/datasets/mlfoundations/dclm-baseline-1.0). 
+It is a small subset of 138,000 samples intended to be used as calibration data for mlx-lm quantizations.
+
+The script used to create the datset:
+
+```python
+import datasets
+
+files = [
+    "global-shard_01_of_10/local-shard_0_of_10/shard_00000009_processed.jsonl.zst",
+    "global-shard_01_of_10/local-shard_0_of_10/shard_00000000_processed.jsonl.zst",
+]
+ds = datasets.load_dataset("mlfoundations/dclm-baseline-1.0", data_files=files)
+ds = ds["train"]
+feats = list(ds.features.keys())
+feats.pop(feats.index("text"))
+ds = ds.remove_columns(feats)
+ds.push_to_hub("mlx-community/dclm-baseline-1.0-138k")
+```
