Could you build this?
No Writing custom low-level NVFP4 tensor execution kernels, integrating sparse attention, and optimizing video diffusion execution on brand-new GPU architectures requires rare CUDA and hardware kernel expertise.
What it would actually take: Requires low-level CUDA, Triton, or TensorRT-LLM C++ development targeting Blackwell/Ada architectures with FP4 quantization and sparse flash-attention implementations. The system wraps these custom compute kernels into PyTorch C++ extensions and hooks them into ComfyUI's model loading pipeline. This requires expert-level GPU hardware microarchitecture knowledge, kernel profiling (via Nsight), and deep generative diffusion internals.
