PyTorch quietly adds CUDA 12.9 support, hinting at major Nvidia driver update
A tiny commit reveals Nvidia's next big CUDA move is already here...
Deep Dive
A recent PyTorch commit shows developers are preparing for CUDA 12.9 by copying FA3 wheel files into new subfolders. The commit notes that CUDA provides forward compatibility for minor versions, meaning wheels built with CUDA 12.6 should also work in 12.8 and 12.9. This subtle backend change is the first public signal that Nvidia's CUDA 12.9 is imminent, requiring framework support ahead of official driver releases.
Why It Matters
This signals a coming Nvidia driver update that will affect performance and compatibility for millions of AI developers.
