Plan limits

The provider does not publish fixed limits for this plan: they are dynamic and depend on load and the chosen model.

How we calculate it

Z.ai estimates the monthly quota at 15–30× the subscription price. We use the conservative 15× lower bound: $18 × 15 = $270, excluding temporary boosts.

ROI = (API value − price) / price = ($270 − $18) / $18 = 1400%.
