How it works
How it works
Evo 2 models and generates DNA over long contexts at single-nucleotide resolution. StripedHyena 2 hybrid architecture combining short, medium and long convolution operators with attention, trained autoregressively at single-base resolution. The documented inputs are DNA sequences represented at single-base resolution. The output consists of next-token outputs, embeddings and generated DNA sequences.
