Per engine, above what your plan includes — a flat $50/mo each, on every paid plan. Starter and Agency Starter include ChatGPT; Growth and Agency Growth include ChatGPT, Gemini, Claude and Google AI Overviews; you add the rest only if you want them. We never charge per model, and since a prompt is one buyer query we run across your plan's engines multiple times, you're never billed per run. See pricing.
