Fair limits for intense use

Mono is built for usage without interruption. To ensure Mono can be offered in the future, limits are introduced that only apply to intense usage. After a certain number of requests to advanced models, Mono automatically falls back to a standard model.

The principal

The best model is used for each request. If the best model is an advanced model, it’s counted. When a limit is hit, Mono automatically uses a standard model for the next requests.

Standard models

Unlimited on Mono.
