Plain language
DeepSeek's system for making each user's text come back much faster without serving fewer people at once.
As stated in the literature
A speculative-decoding serving system pairing a semi-autoregressive drafter (a parallel backbone plus a tiny sequential correction head) with a load-aware scheduler that sets per-request draft length from confidence estimates and live GPU load.
Why it matters: It matters because it cuts the delay users feel without forcing the service to handle fewer people at a time.
For example, when many users hit a chatbot at once, DSpark drafts several likely next tokens in parallel and checks them, so each person's reply still arrives quickly.
