EleutherAI
Open-source AI research for everyone
About EleutherAI
EleutherAI is a grassroots collective of researchers dedicated to open-source AI research and making large language models accessible to the research community. The organization developed influential open-source models including GPT-Neo, GPT-NeoX-20B, and the Pythia model suite, which have been widely used for research and commercial applications.
EleutherAI also created The Pile, a widely-used 800GB open-source text dataset for training language models, and the Language Model Evaluation Harness (lm-eval), which has become the standard tool for evaluating and benchmarking LLMs across the industry. These contributions have been foundational to the open-source AI ecosystem.
Starting as an informal Discord community in 2020, EleutherAI has grown into a respected research organization that publishes peer-reviewed papers and collaborates with academic institutions. The collective operates as a non-profit, funded by grants and donations, with a mission to ensure that AI research remains open and accessible rather than concentrated in a few corporate labs.
