Abstract: Language models (LMs) have become ubiquitous in both NLP research and in
commercial product offerings. As their commercial importance has surged, the
most powerful models have become closed off, gated behind proprietary
interfaces, with important details of their training data, architectures, and
development undisclosed. Given the importance of these details in
scientifically studying these models, including their biases and potential
risks, we believe it is essential for the research community to have access to
powerful, truly open LMs. To this end, this technical report details the first
release of OLMo, a state-of-the-art, truly Open Language Model and its
framework to build and study the science of language modeling. Unlike most
prior efforts that have only released model weights and inference code, we
release OLMo and the whole framework, including training data and training and
evaluation code. We hope this release will empower and strengthen the open
research community and inspire a new wave of innovation.
