At 40 requests/user/day (totaling 600,000 queries/mo), running AI coding assistant on Llama 3.2 90B Vision costs $7,560.00 / month ($15.12 / user / mo).
AI coding assistant for a 500 active users (early growth) audience means 20,000 requests per day on average, each carrying 12,000 input and 2,000 output tokens at a 60% cacheable share — so the effective per-request cost on Llama 3.2 90B Vision is $0.0126, of which $0.00/mo comes back from prompt caching. Per active user that's $15.12/mo — the number to hold against your pricing tier and gross margin. Charging at least $75.60/user/mo keeps gross margin at or above 80%.
