ViroHyena-6m

ViroHyena-6.6M

ViroHyena is a Hyena-based nucleotide language model introduced in the paper ViroBench: Benchmarking Nucleotide Foundation Models on Viral Genomics Tasks.

This specific checkpoint is the 6.6M parameter version. It was pre-trained on the ViroBlend corpus, a 216 Mbp mixed pretraining dataset using source-wise stratified sampling to balance human reference, multi-species genomes, and viral in-domain sequences.

Biosecurity & Responsible Use

This model was developed for biological understanding and measurement research. As noted in the project documentation:

• Do NOT use this model to design, optimize, synthesize, or operationalize harmful biological agents.
• Follow all applicable laws, institutional policies, and biosafety regulations.
• If you release checkpoints or generation outputs, consider controlled access and red-teaming protocols.
