- 5Hacker News·10/13/2026researchA critique of OpenAI’s claimed faster Fourier transform
The article examines OpenAI’s claim of a faster Fourier transform and argues that the supposed breakthrough is likely an artifact of unclear formalism rather than a genuine algorithmic advance. It revisits FFT fundamentals and questions whether the paper actually improves on the standard Cooley-Tukey FFT in any meaningful way.
