At 15 requests/user/day (totaling 1,125,000 queries/mo), running Translation on GPT-5.6 Cyber costs $524,882.813 / month ($209.953 / user / mo).
Translation for a 2,500 active users (series a product) audience means 37,500 requests per day on average, each carrying 5,000 input and 5,500 output tokens at a 15% cacheable share — so the effective per-request cost on GPT-5.6 Cyber is $0.4666, of which $9,492.188/mo comes back from prompt caching. Per active user that's $209.953/mo — the number to hold against your pricing tier and gross margin. Charging at least $1,049.766/user/mo keeps gross margin at or above 80%.
Quick answer
For 2,500 Active Users, Translation on GPT-5.6 Cyber is modeled at 1,125,000 requests per month, costing $524,882.813 per month or $209.953 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.
