Allen Institute for AI

The Allen Institute for AI (AI2) is a non-profit research institute founded by the late Paul Allen, co-founder of Microsoft, with the mission of conducting high-impact AI research and engineering for the common good. AI2 has produced some of the most influential open-source AI tools, models, and datasets used by researchers worldwide.

AI2's contributions include the OLMo family of truly open language models (with open training data, code, and weights), Semantic Scholar (an AI-powered academic search engine), AllenNLP (a widely-used NLP framework), and numerous benchmark datasets. The institute's commitment to full openness — releasing not just model weights but complete training data and code — sets it apart from companies that claim openness while withholding key components.

With a team of world-class researchers and engineers, AI2 publishes extensively in top AI conferences and collaborates with universities and industry partners. The institute focuses on advancing the science of AI while ensuring its benefits are widely accessible, embodying founder Paul Allen's vision of using technology to improve lives.
