Usage assumptions

Estimate traffic and token usage for an average request.
Active seats, customers, or internal users.
Average AI calls per user each day.
Prompt, history, and retrieved context per request.
Generated answer length; SaaS founders should test long replies.
Use 30 for always-on products or fewer for batch jobs.
