OpenAI Just Solved a Problem Open Since 1999. It Still Can't Ask Its Own Question.
OpenAI's Astra has achieved a notable breakthrough by tackling ten complex mathematical problems, one of which had remained unsolved since 1999. The proof not only demonstrates Astra's power within structured contexts but also emphasizes a critical distinction: problem-solving within existing frameworks is not equivalent to the invention of new conceptual frameworks. This reflects on the limits of models in ambiguous exploratory tasks.
