signal brief

Two open-source milestones signal a shift in how large MoE models are served. WASTE (shared on r/LocalLLaMA) claims to run the full 2.78-trillion-parameter Kimi K3 model beyond available RAM by streaming activated experts directly from NVMe, keeping only the model trunk in memory and using a bounded expert cache. If this pattern scales, it reduces the need to hold every expert in HBM/DRAM, making NVMe bandwidth a more central capacity variable in AI inference. In parallel, llama.cpp has been merging DeepSeek-specific kernels at a rapid clip: b10232 adds Metal SIMDgroup-optimized DeepSeek V4 hyper-connection ops, b10237 adds MTP support for DeepSeek V3.2, and b10231 adds DSpark sidecar resolution for speculative decoding. The burst implies nearby model releases (DeepSeek V3.2/V4, Kimi K3) are being optimized for efficiency on commodity and consumer hardware. This is an early, uncorroborated trend rather than a hard capex signal, and the net direction is mixed: bullish for NVMe/storage and local-AI tooling, potentially bearish for the assumption that HBM capacity is the only way to serve giant MoE models.

What the sources said

  • WASTE README via Reddit: "It keeps the model trunk in memory, streams selected experts directly from disk, and uses the remaining RAM as a bounded expert cache."
  • llama.cpp b10232: "Implement GGML_OP_DSV4_HC_COMB, GGML_OP_DSV4_HC_PRE, and GGML_OP_DSV4_HC_POST with SIMDgroup register and shuffle optimized kernels."
  • llama.cpp b10237: "llama : MTP support for DeepSeek V3.2 (#26457)"
  • llama.cpp b10231: "dspark outranks dflash in the auto-selection since its sidecar carries the extra Markov head."
