Pydantic was faster in both shared AI gateway benchmarks.
Median of each benchmark's primary metric; lower is better. Medians within 5% count as roughly even, and a benchmark gets no speed verdict when either provider completed fewer than 50% of runs.
Time for a cold request routed through the gateway to Claude Haiku 4.5 to return its complete response.
Cold end-to-end latency
Pydantic had a 1.55x lower median cold end-to-end latency (393ms vs 608ms for Concentrate AI).
14 runs from July 31, 2026 to October 30, 2026.
Time for a cold request routed through the gateway to GPT-5.4 Mini to return its complete response.
Cold end-to-end latency
Pydantic had a 1.45x lower median cold end-to-end latency (681ms vs 990ms for Concentrate AI).
