Multi-layer Indexer Speeds DeepSeek Sparse Attention Decode

The indexer scan, not sparse attention itself, turns out to be the long-context bottleneck, and reusing selections across layers removes it without any retraining. Teams serving DeepSeek-V3.2 or GLM-5 long-context workloads on SGLang can adopt MLI for faster decode at unchanged accuracy, and it composes with the IndexShare reuse GLM-5.2 already ships.

GC-MoE Operator Accelerates MoE Inference with CUDA Green Contexts

The technique shows that partitioning a single GPU with CUDA Green Contexts removes the resource contention between dispatch warps and GEMM warps that limits fused MoE operators like Mega MoE. Practitioners serving DeepSeek-V4.1-Flash or GLM-5.2 on Hopper or Blackwell clusters can adopt the open-source operator to cut decode latency without extra hardware. The results on H20 GPUs, a China-market chip, make it especially relevant for deployments where H100-class hardware is unavailable.
