Context Before
Source: SemiAnalysis InferenceX ↗
Evidence
Since speculative decoding (including MTP) works by trading excess compute for fewer memory-bound decoding steps, this extra verification work from speculative tokens may not fit cleanly into slack, resulting in smaller improvements at high batch sizes
Context After
In terms of cost, MTP can drive huge cost savings, in the below table, we see that DeepSeek-R1-0528 run on FP4 using Dynamo TRT costs 0.057 per million total tokens.
② Atomic Claim
由於 speculative decoding（包含 MTP）本質上是用額外 compute 換取更少 memory-bound decoding steps，因此在高 batch size 下，speculative tokens 帶來的額外 verification 工作未必能完全塞進閒置 compute，效益可能較小。
