Accelerating inference in genomic and proteomic foundation models via speculative decoding

Abstract Motivation Genomic and protein foundation models (GFMs and PFMs) have demonstrated strong performance in learning the language of DNA and proteins, but their use in large-scale sequence generation is limited by the latency of autoregressive decoding. Because every token triggers a forward pass of a large Trans...

Structure is not mechanism: high-gain gated-FFN rows across text and genomic foundation models

High-gain gated-FFN rows are a recurrent architectural phenotype whose structural prominence acts as an enrichment signal, not a calibrated measure of functional criticality or a specification of causal organization.

Artificial intelligence and biosecurity: capabilities, threat pathways, and defense-in-depth governance

It is argued for defense-in-depth governance that links capability thresholds to proportionate responsibilities across the biological AI ecosystem, reducing high-consequence risk while preserving beneficial use.
