How stable is PyTorch 2.8.0 + CUDA 12.9 for you ?

[NielsGx]

Anyone tried to upgrade to the latest PyTorch version, with CUDA 12.9 toolkit ?

Is it stable ?
Any custom nodes broken ?

XFormers doesn't support it for now (unless locally compiled, I guess)
I use SageAttention2++ anyway so it's not a huge loss (only VAE effectively use XFormers for me, afaik)

It seems Nunchaku also doesn't like it
(But personally I don't like flux so I don't really need it)
