Could you build this?
No Deploying and optimizing a 552B MoE model across multi-node DGX hardware requires custom sm121 GPU kernels, distributed inference tuning, and massive hardware infrastructure.
What it would actually take: Building this requires low-level CUDA and C++ expertise to write and optimize sm121 MXFP4 kernels, alongside deep modifications to vLLM's tensor-parallel distributed runtime and page cache management. Developing and testing this setup necessitates access to multi-node enterprise NVIDIA DGX clusters and high-speed InfiniBand networking.
