How it works
AnySolver records every solve to provider_stats. Auto Fastest reads three rolling windows in order — 12 hours, 48 hours, 30 days — and picks the lowest mean solve time for the requested task type. A window has to contain at least 10 completed tasks to count.
Stats are recomputed hourly. There’s no rolling-mean smoothing on top — you see the same number the routing engine sees.
What the engine sees
Mean solve time per provider. Illustrative numbers; live data appears in your dashboard once you have ten completed tasks per window.

Fallback chain
- 1.12-hour window has ≥10 tasks → use it.
- 2.Else 48-hour window has ≥10 tasks → use it.
- 3.Else 30-day window has ≥10 tasks → use it.
- 4.Else fall back to your Priority list.
- 5.Else fall back to Auto Cheapest.
When to use it
Real-time UX flows where p95 latency matters. User-blocking captcha challenges where you’d pay 2× to shave a few seconds. Anywhere the tail latency of a slow provider becomes the user’s problem.
