The `torch.compile` API itself will not be available from C++. That means that you won't get the pytorch 2.0 performance gains if you use it via C++ API. There's no plan to deprecate the existing C++ API, it should keep working as it is. However, a common theme of all the changes is implementing more of pytorch in python (explicitly the goal of primtorch), so if this plan works it could happen in the long run.
