ViroHyena

ViroHyena is a Hyena-based nucleotide language model pre-trained on the ViroBland (ViroBlend) corpus, a small (216 Mbp) mixed pretraining dataset with source-wise stratified sampling to balance human reference, multi-species genomes, and viral in-domain sequences.

This model was introduced in the paper ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks.
