Could you build this?
No Training a 1.6-trillion-parameter Mixture-of-Experts foundation model on custom AI ASIC superpods requires millions of dollars in compute, specialized distributed training infrastructure, and deep machine learning research.
What it would actually take: Requires deep distributed training expertise (pipeline parallelism, tensor parallelism, 3D/4D parallelism) across thousands of AI accelerator chips (ASICs/TPUs/GPUs). Involves custom sparse attention CUDA/compiler kernels, petabyte-scale data curation and tokenization pipelines, and massive capital expenditure for high-bandwidth fabric networking (InfiniBand/RoCE).
