DeepSeek Just Made AI 85% Faster: DSpark, DeepSpec Explained

Описание: DeepSeek claims ~85% faster AI generation — same model, same hardware, identical tokens.

The trick is DSpark: speculative decoding that drafts cheap tokens, then verifies them in one forward pass. Two production fixes matter:

1) Semi-autoregressive drafting — parallel backbone + tiny sequential head to kill suffix decay
2) Confidence-scheduled verification — only verify prefixes worth the GPU under load

On DeepSeek V4 vs MTP-1: Flash ~60–85% faster per user, Pro ~57–78%, matched throughput, lossless output.

DeepSpec open-sources the training/eval stack for draft heads (incl. Qwen/Gemma targets). Honest catch: the viral number is their V4 serving stack — DeepSpec gives the method, production speed still needs your engine tuned.
