Basecamp Research disclosed EDEN, an evolutionary AI family that designed AI‑generated enzymes enabling programmable insertion of large therapeutic DNA sequences at precise genome locations. The preprint describes EDEN trained on ~9.7 trillion biological tokens from BaseData and reports design success across more than 10,000 disease‑related genomic loci in silico and functional results in cellular assays. The team demonstrated cancer‑fighting sequences integrated into primary human T cells with strong tumor‑cell clearance in lab models. The advance expands beyond small CRISPR edits toward insertion of large payloads and signals rapid progress at the intersection of large‑scale biological data and generative design. Basecamp said it received strategic investment from NVentures to scale applications.
