FineWeb<br/><span>Ultra-large-scale pre-trained dataset</span>
</h1>
<p class="hero-subtitle">
FineWeb is an ultra-large-scale high-quality English web text dataset released by Hugging Face, containing 15 trillion tokens, selected from 96 Common Crawl snapshots, specifically designed for pre-training large language models. It employs a multi-stage data quality filtering pipeline (URL filtering, text extraction, deduplication, model quality scoring), surpassing similar datasets like C4, Dolma, and RedPajama.
