I will discuss the recent calculation (arXiv:2007.06582) of the leading α′ corrections to the entropy of certain black holes with AdS5×S5 asymptotics, namely in the supersymmetric limit, the entropy does not receive α′ corrections. This result strengthens recent calculations that match the index of N=4 Super-Yang-Mills with the corresponding partition function in the supersymmetric limit. In the small temperature regime, the entropy corrections are concordant with the weak gravity conjecture.
