Matryoshka Beats MatFormer in Size-Performance Tradeoff
nthngdy · x · 2026-08-19
Compared to MatFormer, Matryoshka suites offer a better size-performance tradeoff, allow more size flexibility, and deliver variable KV cache requirements. At inference time, speculative decoding is performed using smaller submodels as drafts. Because of nesting, memory and activations are shared, amortizing the draft overhead and achieving 10-30% faster decoding.
