Major ecosystem libraries like PyTorch and CuPy now build on the shared cuda.core foundation, reducing version conflicts and interop bugs for developers. With CUDA 13.3, @nvidia released CUDA Python 1.0, the libraries and tools that give you the full CUDA platform from Python. Using standard CUDA context, devices, streams, and memory are shared with the rest of the Python GPU ecosystem, so your own kernels can run against CuPy arrays or PyTorch tensors without copying data.

Flash Attention from Scratch in CUDA and CuPy

what attention actually is: attention takes three matrices, queries, keys, and values, and computes a weighted blend of the value vectors where the weights come from how similar each query is to each
