public class RateLimitException
extends RetriableException

Thrown when the model provider rejects a request because the caller has exceeded its allowed request or token quota within a time window (HTTP 429).

This is a RetriableException: the request may succeed once the rate-limit window resets. Callers should implement an exponential back-off strategy before retrying.
