AI API latency, week of 20 July 2026: what actually moved
· covers 20 July 2026
Week of 20 July 2026: 3 different providers were fastest across the 4 regions we measure from, and nothing moved by more than a quarter against the week before.
Who led each region last week?
| Region | Fastest | p50 TTFB | Uptime |
|---|---|---|---|
| Asia (Tokyo) | fireworks | 16 ms | 100% |
| Europe (Germany) | nscale | 98 ms | 100% |
| South America (São Paulo) | openrouter | 56 ms | 100% |
| US (Central) | fireworks | 27 ms | 100% |
What changed by more than 25%?
Nothing did. A quiet week is a result too, and reporting it is the only way the noisy weeks mean anything.
