The dataset includes over 100B text documents coming from 84 CommonCrawl snapshots and processed using the [CCNet](https://github.com/facebookresearch/cc_net) pipeline. Out of these, there are 30B documents in the corpus that additionally come with quality signals. In addition, we also provide the ids of duplicated documents which can be used to create a dataset with 20B deduplicated documents. Check out our [blog post](https://together.ai/blog/redpajama-data-v2) for more details on the build process, dataset structure and schema. A full set of scripts to recreate the dataset, including the quality signals, can be found [here](https://github.com/togethercomputer/RedPajama-Data). #### Downloading the raw Dataset with Quality Annotations To familiarize yourself with the dataset, you can load the sample dataset using: ```python from datasets import load_dataset ds = load_dataset("togethercomputer/RedPajama-Data-V2", name="sample") ``` To download a the dataset for a specific combination of `{partition} x {snapshot_id} x {language}`, you can use the following command which downloads the raw (i.e., *not* deduplicated) part of the dataset and the corresponding quality signals. In the example below, we use English and German data from the `head_middle` partition of the 2023-06 and the 2022-49 snapshots. The full set of available snapshots is specified in `_CC_SNAPSHOT_IDS`. The available partitions are `tail` and `head_middle`. The available language tags are `en`, `de`, `fr`, `es`, `it`. _Note that this will download the entire snapshots specified in the `snapshots` argument and requires ~1TB of disk space per snapshot_. ```python from datasets import load_dataset ds = load_dataset("togethercomputer/RedPajama-Data-V2", name="default", partition="head_middle", snapshots=["2023-06", "2022-49"], languages=["en", "de"]) ``` #### Downloading the dataset via wget If you prefer to download the full dataset via wget, you can download the following lists of urls and use them to download the dataset: ```bash # get list of urls pointing to the text documents wget "https://data.together.xyz/redpajama-data-v2/v1.0.0/urls/document-urls.txt" -O "document-urls.txt" # get list of urls pointing to the quality signals wget "https://data.together.xyz/redpajama-data-v2/v1.0.0/urls/quality_signals-urls.txt" -O "quality_signals-urls.txt" # get list of urls pointing to the ids of duplicate documents wget "https://data.together.xyz/redpajama-data-v2/v1.0.0/urls/duplicates-urls.txt" -O "duplicates-urls.txt" # get list of urls pointing to the minhash signatures wget "https://data.together.xyz/redpajama-data-v2/v1.0.0/urls/minhash-urls.txt" -O "minhash-urls.txt" ``` You can also directly download subsets of the dataset using the following instructions. Here we use English data from the `2023-06` snapshot and the `head_middle` partition as an example. The full set of CC snapshots included in the dataset is given in `_CC_SNAPSHOT_IDS`. The available partitions are `tail` and `head_middle`. The available language tags are `en`, `de`, `fr`, `es`, `it`. To download the plain text data, available for both the `head_middle` and `tail` partitions, you can run ```bash CC_SNAPSHOT="2023-06" LANG="en" PARTITION="head_middle" BASE_URL="https://data.together.xyz/redpajama-data-v2/v1.0.0" listings_tag="${LANG}-${CC_SNAPSHOT}-${PARTITION}" mkdir listings wget "${BASE_URL}/listings/${listings_tag}.txt" -O "listings/${listings_tag}.txt" listings_file="listings/${listings_tag}.txt" # download documents while read line; do url="${BASE_URL}/documents/${line}.json.gz" dest="documents/${line}.json.gz" mkdir -p $(dirname $dest) wget "$url" -O "$dest" done <"$listings_file" ``` In addition, for the `head_middle` partition, you can also download the quality signals, minhash signatures and duplicate ids using the following commands: ```bash CC_SNAPSHOT="2023-06" LANG="en" BASE_URL="https://data.together.xyz/redpajama-data-v2/v1.0.0" listings_tag="${LANG}-${CC_SNAPSHOT}-head_middle" mkdir listings wget "${BASE_URL}/listings/${listings_tag}.txt" -O "listings/${listings_tag}.txt" listings_file="listings/${listings_tag}.txt" # download quality signals while read line; do url="${BASE_URL}/quality_signals/${line}.signals.json.gz" dest="quality_signals/${line}.signals.json.gz" mkdir -p $(dirname $dest) wget "$url" -O "$dest" done <"$listings_file" # download other components COMPS=("minhash" "duplicates") for comp in "${COMPS[@]}"; do while read line; do url="${BASE_URL}/${comp}/${line}.${comp}.parquet" dest="${comp}/${line}.${comp}.parquet" mkdir -p $(dirname $dest) wget "$url" -O "$dest" done <"$listings_file" done ``` ### Applying Filtering Rules You can use the quality signals to filter the raw RedPajama-V2 dataset for a given set of rules. For example, consider the following set of rules used in Gopher: ```python def gopher_rules_pass(sample) -> bool: """ function returns True if the sample complies with Gopher rules """ signals = json.loads(sample["quality_signals"]) # rule 1: number of words between 50 and 10'000 word_count = signals["rps_doc_word_count"][0][2] if word_count < 50 or word_count > 100_000: return False # rule 2: mean word length between 3 and 10 mean_word_length = signals["rps_doc_mean_word_length"][0][2] if mean_word_length < 3 or mean_word_length > 10: return False # rule 2: symbol to word ratio below 0.1 symbol_word_ratio = signals["rps_doc_symbol_to_word_ratio"][0][2] if symbol_word_ratio > 0.1: return False # rule 3: 90% of lines need to start without a bullet point n_lines = signals["ccnet_nlines"][0][2] n_lines_bulletpoint_start = sum(map(lambda ln: ln[2], signals["rps_lines_start_with_bulletpoint"])) if n_lines_bulletpoint_start / n_lines > 0.9: return False # rule 4: the ratio between characters in the most frequent 2-gram and the total number # of characters must be below 0.2 top_2_gram_frac = signals["rps_doc_frac_chars_top_2gram"][0][2] if top_2_gram_frac > 0.2: return False # rule 5: ... return True ``` Filtering the RedPajama-V2 dataset with this set of rules is then as easy as: ```python ds_iterator = load_dataset( "togethercomputer/RedPajama-Data-V2", snapshots=["2023-14"], languages=["en"], name="default", streaming=True ) filtered_dataset = [] for sample in ds_iterator["train"]: if not gopher_rules_pass(sample): continue filtered_dataset.append(sample) ``` ### Dataset Summary RedPajama-V2 is an open dataset for training large language models and includes over 100B text documents.

Each snapshot was processed using the CCNet pipeline and split into `head` `middle` `tail` buckets, depending on the perplexity score. In a second step, the documents in the `head` and `middle` buckets were annotated with the quality signals described above. Finally, the documents were deduplicated based on the text, using a Bloomfilter. The duplicates were kept in the dataset, but are marked in the `duplicates` component. ## Citation To cite RedPajama, please use: ``` @software{together2023redpajama, author = {Together Computer}, title = {RedPajama: an Open Dataset for Training Large Language Models}, month = October, year = 2023, url = {https://github.com/togethercomputer/RedPajama-Data} } ``` You can also cite the paper describing this dataset ```bibtex @misc{weber2024redpajamaopendatasettraining, title={RedPajama: an Open Dataset for Training Large Language Models}, author={Maurice Weber and Daniel Fu and Quentin Anthony and Yonatan Oren and Shane Adams and Anton Alexandrov and Xiaozhong Lyu and Huu Nguyen and Xiaozhe Yao and Virginia Adams and Ben Athiwaratkun and Rahul Chalamala and Kezhen Chen and Max Ryabinin and Tri Dao and Percy Liang and Christopher Ré and Irina Rish and Ce Zhang}, year={2024}, eprint={2411.12372}, archivePrefix={arXiv}, primaryClass={cs.CL}, url={https://arxiv.org/abs/2411.12372}, } ``` ## Acknowledgements We are appreciative to so many partners and collaborators that together are pushing forward the frontier of open LLM models. - Thank you to the OLMo team at AI2 and friends at OpenGPT-X for the insightful discussions about datasets and data quality!
