Imagine if we could predict the evolution of viruses, potentially stopping the next pandemic before it starts. Researchers are exploring a groundbreaking approach using large language models (LLMs), the same technology behind AI chatbots, to forecast how viruses like SARS-CoV-2 might mutate. In a new study, scientists trained an LLM called VirusT5 to treat viral mutation like translating a language. By feeding VirusT5 the genetic sequence of a virus, it learns the 'grammar' of mutation and can then predict future genetic changes. This 'mutation-as-translation' concept lets VirusT5 generate potential future virus strains, effectively simulating evolution. The model achieved remarkably high accuracy in identifying known variants and mutation hotspots within the virus's genetic code. While the research primarily focused on single generations of SARS-CoV-2 within a lineage, the results are promising. The ability to simulate viral evolution over multiple generations opens doors to preemptive vaccine development, faster responses to emerging variants, and a better understanding of how viruses evolve over time. Challenges remain, including the need for more refined data on true parent-child viral relationships. However, using LLMs to decode the language of viruses offers a powerful new tool in the fight against infectious diseases and could revolutionize pandemic preparedness.
