  "question": "How do I estimate AI research assistant cost per report?",
  "canonical_url": "https://www.unitcostai.com/guides/ai-research-assistant-cost-per-report",
  "related_tool_url": "https://www.unitcostai.com/tools/reranking-cost",
  "formula": "cost_per_report = requests_per_report * cost_per_request",
  "assumptions": [
    "One report includes search, synthesis, and revision turns instead of one isolated prompt",
    "Cost per request includes retrieval, reranking, and any premium-model second pass used in the workflow",
    "Requests per report should be measured from real completion traces, not one ideal path"
  ],
  "example": "18 requests per report at 0.11 cost per request gives 1.98 cost per completed report."
