Key points

  • MoE architectures enable large models on limited VRAM via expert offloading, but suffer from consistency issues for agentic tasks.
  • Attention mechanisms like GQA, MLA, SWA, and Gated DeltaNet each offer different memory-performance trade-offs.
  • Speculative decoding with MTP drafters can boost inference speed up to 3x without quality loss.
  • Hardware sets the ceiling, but software optimizations (quantization, offloading) can yield 3-5x performance differences.
