Hugging Face Research
\nThe science team at Hugging Face is dedicated to advancing machine learning research in ways that maximize value for the whole community.
\n🛠️ Tooling & Infrastructure
\nThe foundation of ML research is tooling and infrastructure and we are working on a range of tools such as datatrove, nanotron, TRL, LeRobot, and lighteval.
\n📑 Datasets
\nHigh quality datasets are the powerhouse of LLMs and require special care and skills to build. We focus on building high-quality datasets such as no-robots, FineWeb, The Stack, and FineVideo.
\n🤖 Open Models
\nThe datatsets and training recipes of most state-of-the-art models are not released. We build cutting-edge models and release the full training pipeline as well fostering more innovation and reproducibility, such as Zephyr, StarCoder2, or SmolLM3.
\n🌸 Collaborations
\nResearch and collaboration go hand in hand. That's why we like to organize and participate in large open collaborations such as BigScience and BigCode, as well as lots of smaller partnerships such as Leaderboards on the Hub.
\n⚙️ Infrastructre
\nThe research team is organized in small teams with typically <4 people and the science cluster consists of 96 x 8xH100 nodes as well as an auto-scalable CPU cluster for dataset processing. In this setup, even a small research team can build and push out impactful artifacts.
\n📖 Educational material
\nBesides writing tech reports of research projects we also like to write more educational content to help newcomers get started to the field or practitioners. We built for example the alignment handbook, the evaluation guidebook, the pretraining tutorial, or the FineWeb blog.
