Reference data — not yet measured from live traffic

PROVIDER		MAX OUT		OUTPUT /M				QUANT

Azure AI Foundry	131K	33K	$3.30	$16.50	860ms	66	99.60%	Full

Latency p50 reflects a provider’s API endpoint responsiveness — the round-trip to its API, not per-token inference time. These figures, with throughput and uptime, are reference data until the gateway aggregates its own traffic.
