About
Marin is an open-source initiative by the Marin Community in close collaboration with Stanford University's Center for Research on Foundation Models (CRFM). Focused on building foundation models with emphasis on reproducibility, interpretability, and safety evaluation. Marin models use activation steering and refusal mechanisms for safer outputs, and support research in mechanistic interpretability.
