OpenAI math repo's 'exact complex arithmetic' claim draws fire over arbitrary-precision assumption
jessi_cata · x · 2026-10-13
jessicata weighs in on criticism of OpenAI's math repo. The quoted post argues that the claim 'the model uses exact complex arithmetic' — i.e., assuming you can store and multiply complex numbers at arbitrary precision — is a far more compelling critique than sociological complaints about theory divorced from practice. jessicata adds that 'exact complex arithmetic' isn't even the right computational-complexity definition, suggesting instead the complexity of operating on Cauchy sequences of rationals.
