Truly open AI research
The Allen Institute for AI (Ai2) was founded in 2014 by Microsoft co-founder Paul Allen, with Oren Etzioni as founding CEO, to conduct high-impact AI research for the common good. Under CEO Ali Farhadi, Ai2 has become the standard-bearer for 'truly open' AI: its OLMo language models ship not just weights but full training data, code, logs and intermediate checkpoints, enabling genuine scientific reproducibility.
Model family and tools
Ai2's portfolio includes OLMo (open language models), Molmo (open multimodal models), Tulu (open post-training recipes and models), and the Dolma pretraining corpus. Beyond models, Ai2 runs Semantic Scholar, an AI-powered research discovery platform indexing hundreds of millions of papers, and applied programs in conservation and climate such as EarthRanger, Skylight and OlmoEarth.
Impact
Backed by partnerships with the NSF, NVIDIA, Google Cloud and the University of Washington, Ai2 provides the open scientific baseline that academic labs, startups and governments use to study and build language models without black boxes — making it one of the most consequential non-profit labs in AI.
