Rate limit

A cap on how many requests or tokens you can send to an AI service in a period, enforced to protect capacity.

Definition

Rate limits are expressed as requests or tokens per minute or day and vary by plan and model. Hitting them produces errors or slowdowns, which matters for automations and agents that make many calls. Higher tiers, batching, caching, and queueing help stay within limits.

Why it matters when choosing a tool

Rate limits determine whether a tool can support your volume; automation and agent workloads should be designed to handle them gracefully.
