At 4 requests/user/day (totaling 12,000,000 queries/mo), running Document summarization on Grok Build 0.1 costs $290,400.00 / month ($2.904 / user / mo).
Document summarization for a 100,000 active users (high-volume consumer / enterprise) audience means 400,000 requests per day on average, each carrying 25,000 input and 600 output tokens at a 10% cacheable share — so the effective per-request cost on Grok Build 0.1 is $0.0242, of which $24,000.00/mo comes back from prompt caching. Per active user that's $2.904/mo — the number to hold against your pricing tier and gross margin. Charging at least $14.52/user/mo keeps gross margin at or above 80%.
Quick answer
