Published limits.
The bench is free, so its capacity is published exactly. Every number below is the number the gate enforces — nothing hidden, nothing arbitrary.
How they are enforced
Anonymous clients are keyed by a salted, rotating hash of their network address — Schott never stores the address itself, and the key rotates daily. Every window is consumed atomically at job creation, so the count you see is the count the server holds.
When a limit is hit, the bench answers 429 with a machine-readable Retry-After — and the panel shows a countdown to the next window. One enhancement runs at a time per client.
Why limits at all
Enhancement consumes GPU time. The published windows keep the service free and fast for everyone, and the daily global budget protects it from automated bulk use. If the budget is exhausted for the day, the bench says so and reopens at the next window.
Retention
