Rate Limit

Rate limits cap how many requests or tokens you can send per window. Hitting them triggers retries that raise cost.

Definition

A rate limit is a cap on requests or tokens per minute/hour set by the provider.

Why it matters for cost

When you hit a limit, your app usually retries. Retries multiply calls and tokens, quietly inflating cost during traffic spikes.

Practical tip

Add backoff and retry caps. Unbounded retries turn a throttling event into a cost spike.
