asa	also this is very useful thanks, i didn't know something like cuda-legacy existed	23:08:50
connor (burnt/out) (UTC-8)	NVIDIA has historically published two "arm" builds: `linux-sbsa` and `linux-aarch64`. These both map to Nixpkgs' `aarch64-linux` platform, but `linux-sbsa` is for server-grade ARM and `linux-aarch64` for Jetsons. Going forward, it seems new Jetson devices will also use `linux-sbsa` (e.g., the Jetson Thor). It remains to be seen whether older Jetson devices will be supported on CUDA 13.	23:09:20
connor (burnt/out) (UTC-8)	It's still very much a work in progress and best-effort, so beware 👻	23:10:04

Maybe a red herring, but I'm running a fresh build of vLLM to see if the new JAX version (and hence Outlines) breaks vLLM.	23:21:15
