Australian tech entrepreneur Paul Conyngham, who has no background in biology or medicine, claimed that ChatGPT helped his dog, Rosie, from cancer. Conynogham used chatbot to suggest treatment options and then used Google's protein structure AI model AlphaFold to help make sense of the results. He developed a personalized mRNA vaccine tailored to Rosie's tumor mutations and administered it alongside another form of immunotherapy. However, it is unclear if the vaccine had any effect. The story was widely reported as a "cure" and a sign of a new era of personalized medicine. Despite these efforts, critics argue that the model is not yet validated for predicting the effects of some mutations and does not model several biologically important contexts.
