So as there has been a recent preprint by fauzan( if i am spelling it right) on the irrationality of zeta 5 uploaded to zenodo on 17th september and the discussions on reddit took place yesterday. Today, while scrolling through reddit I saw that the zeta 5 irrationality has been formalized in lean so I searched out of fun zeta 7 on zenodo and got a preprint which too looks real and it has just been published a few hours ago most likely. Feeding this into models, I haven't found any fatal issue except a few repairable typos.
I am not sure if any of these I mentioned is wrong but till now it appears this way and I just shared this because I was too excited haha.
Edit: This now looks wrong as also suggested by few replies under this thread. It leads to an exponential reversal showing growth rather than a decay, whether the paper is repairable is not yet known but the proof is invalid as of now.
