Dual Blackwell GPUs run 167 GB DeepSeek-V4 FP8

High-performance local inference for massive open models is becoming practical on workstation hardware thanks to next-generation Blackwell GPUs and FP8 quantization. Fitting a ~167 GB FP8 model natively across dual 96 GB VRAM GPUs eliminates system RAM offloading bottlenecks. Integrating DeepSeek-V4-Flash with DSpark speculative decoding maximizes local throughput and latency performance while providing an actionable hardware blueprint for developers hosting enterprise-grade open LLMs locally.
