A new, forthcoming book by Peter Lee, Carey Goldberg, and Isaac Kohane, with Sebastian Bubeck. The researchers were given advance access to GPT-4 (with no editorial controls), and this book documents the power of the results, for instance:
In our testing, when given a full battery of USMLE [medical licensing exam] problems, GPT-4 answers them correctly more than 90 percent of the time.
And it can give very good explanations.
Due out May 13, this book is the documentation, definitely recommended, especially for the skeptics.
