How it works
Reliable mode picks the provider whose recent solve attempts are most likely to succeed. Two rolling windows — 48 hours and 30 days — read from the same provider_stats table that powers Auto Fastest. A window needs at least 10 completed tasks for the engine to trust it.
If neither window meets the threshold, the engine falls back to your Priority list, then to Auto Cheapest.

When to use it
High-value workflows. Payment flows. Account-creation gates. Anywhere a failed solve costs more than a few cents in user friction or rework.
