At 200 requests/user/day (totaling 15,000,000 queries/mo), running Data extraction & tagging on Cerebras — GPT OSS 120B costs $13,312.50 / month ($5.325 / user / mo).
Data extraction & tagging for a 2,500 active users (series a product) audience means 500,000 requests per day on average, each carrying 2,000 input and 250 output tokens at a 20% cacheable share — so the effective per-request cost on Cerebras — GPT OSS 120B is $0.000887, of which $0.00/mo comes back from prompt caching. Per active user that's $5.325/mo — the number to hold against your pricing tier and gross margin. Charging at least $26.625/user/mo keeps gross margin at or above 80%.
Quick answer
For 2,500 Active Users, Data extraction & tagging on Cerebras — GPT OSS 120B is modeled at 15,000,000 requests per month, costing $13,312.50 per month or $5.325 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.
