That's wildly misleading then. It would be interesting to see how GPT-4, properly augmented with actual medical literature, would do.
They focus on the more specific problem of preventing drug misuse (checking interactions w/ other drugs and diseases, pathologies, etc). They use GPT-4 + RAG with qdrant and return the exact source of the information highlighted in the data. They are expanding their test set - they use real questions asked by GPs - but currently they have 0 % error rate (and less than 20 % cases where the model cannot answer).
But given the vagueness of the wording, much is going to depend on the details.
