ProGen2 Medium

Generate up to 3 plausible protein sequence continuations from an N-terminal context using a 764M-parameter ProGen2 autoregressive transformer trained on ∼1B diverse natural proteins (UniRef90+BFD30). The GPU-accelerated service supports contexts and generated lengths up to 512 residues, with configurable temperature and nucleus (top-p) sampling. Typical uses include exploring sequence variants for protein engineering, library design, and hypothesis testing while scoring variants by log-likelihood.
