Screening of Biosecurity Features in Metagenomic Data with Evo 2 Probes
Genomic foundation models such as Evo 2 learn rich sequence representations, but their value for biosecurity screening is largely unexplored. We ask how much biosecurity relevant signal is linearly accessible in these representations by training minimal linear and attention probes on frozen Evo 2 layer 26 activations, without fine tuning the underlying model. Across held out metagenomic test sets, the probes detec...
