Ai2 and Hugging Face are expanding their partnership to make fully open AI easier to access and deploy. Since spring 2024, our models and datasets have been downloaded more than 50 million times from the Hugging Face Hub. Both are part of Hugging Face's Hugging Science Collabs collection , which tracks artifacts produced through partnerships with the Hugging Science community. Ai2 develops foundational AI research, open models, and tools—including Olmo, Molmo, and OlmoEarth—to advance AI that serves the public good. Its open-source libraries and the Hugging Face Hub are used by researchers and developers worldwide to build, share, and deploy AI.
