At 8 requests/user/day (totaling 12,000 queries/mo), running Agentic workflow on GPT-5.6 Cyber costs $3,840.00 / month ($76.80 / user / mo).
Agentic workflow for a 50 active users (private beta) audience means 400 requests per day on average, each carrying 40,000 input and 1,500 output tokens at a 65% cacheable share — so the effective per-request cost on GPT-5.6 Cyber is $0.32, of which $3,510.00/mo comes back from prompt caching. Per active user that's $76.80/mo — the number to hold against your pricing tier and gross margin. Charging at least $384.00/user/mo keeps gross margin at or above 80%.
Quick answer
For 50 Active Users, Agentic workflow on GPT-5.6 Cyber is modeled at 12,000 requests per month, costing $3,840.00 per month or $76.80 per active user.
Method & trust
This projection combines the selected active-user tier, requests per user per day, input/output tokens per request, and the modeled cache share. It is an operating estimate, not a provider invoice; production traffic and retries should be measured against it.
