Triton is a backend for PyTorch. Lately it is the backend. So it's definitely double digits percentage if not over 50%.

It's the backend for torch.compile, pytorch eager mode will still use cuBLAS/cuDNN/custom CUDA kernels, not sure what's the usage of torch.compile

consider that at minimum both FB and OAI themselves definitely make heavy use of the Triton backend in PyTorch.

Doesn’t triton write its own intermediate language that then compiles to PTX?

It has a fairly standard MLIR pipeline

Yes and?
