Verification: full_text; confidence=high. Question: Can speculative decoding exploit multiple draft continuations while exactly preserving the target LLM's output distribution? Context: A single small draft model can propose poor tokens, limiting acceptance and leaving target-model parallelism unused. Method: SpecInfer has multiple small models construct a token tree, then verifies tree nodes in parallel with the target LLM using distribution-preserving acceptance. Evaluation: workloads=distributed LLM inference; offloaded LLM inference; baselines=existing LLM serving systems; metrics=inference speedup; accepted speculative tokens; output-distribution fidelity; results=1.5–2.8x distributed speedup; 2.6–3.5x offloading speedup Interpretation: Branching speculation converts uncertain draft quality into parallel target-model verification. Reusable lesson: When cheap predictors are uncertain, aggregate diverse candidates and verify them in one expensive parallel pass. Applicability: Autoregressive LLM serving with distributed or offloaded target models. Limits: Benefit depends on draft accuracy, token-tree construction cost, target parallelism, model pair, and hardware.
