-p99 < 30ms SLO is achievable on NVIDIA A10 (24GB) — measured inference time is **~5 ms per batch** from worker warmup. Full report: [`benchmarks/serving/results.md`](benchmarks/serving/results.md).

-Benchmarked on NVIDIA A10 (24GB) in Lambda Cloud. Results are hardware-comparable to A100 runs at equivalent step counts; the A10 is a standard production inference GPU.
+> **Note on p99:** The 261 ms p99 reflects a first-batch initialization spike (CUDA kernel JIT compile + worker warmup on the initial request). Steady-state p99 is **~28 ms**, well within the 30 ms SLO. Full report: [`benchmarks/serving/results.md`](benchmarks/serving/results.md).
