Limits apply per account across its keys. Daily allowances reset at 00:00 UTC. Cached input does not consume the new-input allowance. Reasoning counts as output. Free and student keys share capacity at the same priority; the student pass does not reserve capacity. All plans share the service's available capacity.
Your own usage, remaining allowance, keys, balance and invoices are available after sign-in.
