At 200 requests/user/day (totaling 60,000 queries/mo), running Data extraction & tagging on Muse Spark 1.2 Contributor (OpenRouter) costs $15.00 / month ($1.50 / user / mo).
Data extraction & tagging for a 10 active users (alpha / internal testing) audience means 2,000 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 Muse Spark 1.2 Contributor (OpenRouter) is $0.00025, of which $0.00/mo comes back from prompt caching. Per active user that's $1.50/mo — the number to hold against your pricing tier and gross margin. Charging at least $7.50/user/mo keeps gross margin at or above 80%.
Quick answer
For 10 Active Users, Data extraction & tagging on Muse Spark 1.2 Contributor (OpenRouter) is modeled at 60,000 requests per month, costing $15.00 per month or $1.50 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.
