A week after OpenAI presented ten mathematical results produced by its upcoming Astra model, several named mathematicians say the write-ups reuse published ideas without citing them. Steven Miller of Yeshiva University says the sphere-packing result rests on an argument from a 2016 paper of his own; Francesco Fournier-Facio of the University of Cambridge says the group-theory result is an elementary combination of 2016 and 2019 work by Gábor Kun and Andreas Thom, presented as a new discovery. OpenAI has softened its original claim that the problems had seen no progress for at least a decade. A spokesperson said the company takes responsibility for the correctness of the results, holds itself to the standards expected of human mathematicians, and will make small updates to the paper.
