Evo Models Used To Design BacteriophagesThe researchers used Evo 1 and Evo 2, AI models trained to identify patterns in genetic sequences. The models were used to design bacteriophages, viruses that infect bacteria, rather than viruses that infect humans. More capable systems could eventually generate biological sequences with properties that are difficult to assess against existing genetic databases. It highlights the need to assess how screening methods perform as biological design moves further from naturally occurring sequences. The 16 successful genomes nevertheless showed that AI can generate previously unseen genetic sequences that work inside living cells.
