# TxT360: a globally deduplicated dataset for LLM pretraining
<center><img src="llm360_logo(1).png" alt="k2 eval table" /></center>
## We introduce TxT360 (Trillion eXtracted Text) the first dataset to globally deduplicate 99 CommonCrawl snapshots and 14 commonly used non-web data sources (e.g. FreeLaw, PG-19, etc.) providing pretraining teams with a recipe to easily adjust data weighting and train the most performant models.

** TxT360 does not include code. This decision was made due to the perceived low duplication code with other sources.
Complete details on the dataset can be found in our blog post [here](https://huggingface.co/spaces/LLM360/TxT360-New).
## Initial Data Representation
To produce TxT360, a comprehensive and transparent data processing pipeline was designed to account for the nuances of both web and curated datasets. The pipeline presents a unified framework for processing both data types, making it convenient and easily adaptive for users to revise and fine-tune the pipeline for their own use cases.
Web datasets are inherently noisy and varied. The TxT360 pipeline implements sophisticated filtering and deduplication techniques to clean and remove redundancies while preserving data integrity.
Curated datasets are typically structured and consistently formatted. TxT360 filters these sources with selective steps to maintain their integrity while providing seamless integration into the larger dataset. Both data source types are globally deduplicated together resulting in 5.7T tokens of high-quality data. The table below shows the source distribution of TxT360 tokens.

## CommonCrawl Data Filtering
Follow [this link](https://llm360-txt360-new.hf.space/webdata#section1) to view all steps taken to filter the web data.
## Curated Source Filtering
Each data source was filtered individually with respect to the underlying data. Full details and discussion on how each source is filter is covered [here](https://llm360-txt360-new.hf.space/curated#section1).
## Global Deduplication
After the web and curated sources were filtered, they were globally deduplicated to create TxT360. The deduplication process is available [here](https://llm360-txt360-new.hf.space/common#section2).
