# protoLabs lab-benchmarks

Every number on a protoLabsAI model card traces to a row here. Release-gate results
(quant vs bf16 baseline, paired task sets, outliers re-trialed x3 both sides), speed-test-v2
regime matrices (InferenceMAX-style: seeded random dataset, client-side TTFT/TPOT p50/p99,
goodput), decode-at-depth ladders, and coherence-probe verdicts.

Methodology: single-stream-only numbers are never published without load numbers;
spec-decode accept% is reported per workload (random-data benches understate it ~2.5x);
LLM-judged suites are gated behind deterministic ones. Harness: protoLabsAI/protoLab evals.
