The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

TTS improves acceptance lengths over state-of-the-art speculators by up to 72% and 41% on average, with the benefits scaling with increased generation lengths.

C2weakest assumption

That continuous online updates to the draft model remain stable and do not introduce latency, divergence, or quality degradation over very long generations, and that the verification signals provide sufficient training data without distribution shift issues.

C3one line summary

Test-Time Speculation adapts draft models online via target-model verifications to sustain high acceptance lengths during long LLM generations.
