ProGen2 OAS

Generate up to 3 antibody VH sequences autoregressively using the OAS-trained ProGen2 variant, conditioned on an OAS-style germline framework provided as context. Sampling controls (temperature, top-p) and a configurable maximum sequence length of 12–512 amino acids allow exploration of VH sequence diversity within realistic immune-repertoire constraints. Typical uses include constructing in silico VH libraries for downstream screening, developability profiling, and integration into antibody engineering workflows.
