Could you build this?
No It implements FP4 attention forward and backward passes with numerical analysis of stochastic rounding and gradient behavior, which is novel GPU kernel and ML research requiring CUDA and numerics expertise.
What it would actually take: A real version needs hand-written or Triton/CUTLASS FP4 kernels on recent NVIDIA hardware, correct tensor-core block-scaling formats, and validated gradients against FP16/BF16 baselines. The analysis part requires ML research skills in quantization and numerical stability, plus access to high-end GPUs for benchmarking.
