โก Architecture & Throughput Transparency: Single-user decode speed (~83 tok/s) is memory-bandwidth bound at batch size = 1 on NVIDIA DGX Spark (128GB Grace-Blackwell Unified) (273 GB/s). Prompt prefill / TTFT (~1,204 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
