Open Athena
Open Athena is a nonprofit that accelerates academia with capabilities from the AI frontier
AI is transforming how discovery happens, but the ability to build and adapt large foundation models is concentrated inside industry.
Open Athena provides labs with engineers, compute, and coordination to transform promising prototypes into breakthrough foundation models that are developed openly and sustained within academic systems.
