Chai Discovery is an AI biology company developing unified foundation models for molecular prediction. Its flagship model, Chai-1, enables the simultaneous prediction of structures for proteins, small molecules, DNA, RNA, and their interactions. By moving beyond single-modality limitations, Chai Discovery accelerates drug design by accurately modeling how biochemical entities bind and function in complex, real-world scenarios. The approach compresses traditional R&D timelines, offering systemic cost reductions in therapeutic development and biological engineering.
