Consistency diffusion language models: Up to 14x faster, no quality loss
Standard diffusion language models can't use KV caching and need too many refinement steps to be practical. CDLM fixes both with a post-training recipe that enables exact block-wise KV caching and trajectory-consistent step reduction — delivering up to 14.5x latency improvements

AVX2 is slower than SSE2-4.x under Windows ARM emulation
If you compile your app for AVX2 and it runs on Windows ARM under Prism emulation, is it faster or slower than compiling for SSE2-4.x? I assumed it would be roughly the same — maybe slightly slower due to emulation overhead, but AVX2's wider operations would compensate. The
