Latent-X2 is Latent Labs’ generative model for designing antibodies and macrocyclic peptides. It jointly generates molecular sequences and all-atom structures, conditioned on a target structure, an epitope specification, and, optionally, an antibody framework. Latent Labs reports laboratory validation of antibody designs across VHH and scFv formats, including binding and developability assessments, and ex vivo immunogenicity testing of selected VHH binders. The model is accessed through the Latent Labs Platform, which offers browser-based workflows and API integration.
