EleutherAI is a non-profit artificial intelligence (AI) research group. The group, considered an open-source version of OpenAI, was formed in a Discord server in 2020 to create an open-source version of GPT-3. In early 2023, it formally incorporated as the EleutherAI Institute, a non-profit research institute. As of 2025, the nonprofit maintains widely-used training datasets, conducts research, and is involved in public policy, among other activities.
