DeepSeek Harness y DeepSelect: Atención Dispersa Optimizada con BLAS para Máximo Rendimiento

DeepSeek has published **deepseek-harness**, the inference and plugin orchestration harness powering its web and API infrastructure.

DeepSelect & DeepGEMM deepseek-harness open-sources DeepSelect—a GPU-accelerated routing kernel that evaluates attention sparsity in real-time, executing Dynamic Sparse Attention (DSA) with near-zero latency overhead. Paired with DeepGEMM FP8 matrix operations, self-hosted clusters achieve up to a 3.4× boost in tokens-per-second-per-GPU.
