- What happened
- Prime Flash MoE delivers Blackwell-optimized CUDA kernels for mixture-of-experts models, achieving 2.4x speedup over PyTorch grouped GEMM by avoiding intermediate tensor materialization.
- Why it matters
- Matters for engineers optimizing MoE inference on Blackwell GPUs, especially when memory bandwidth and latency are bottlenecks in production deployments.
- Watch out
- Kernel includes two pipelines with different tradeoffs; fused path wins at small problem sizes while split path performs better as working sets grow and cache locality degrades.
