AI Coding Seat vs. BYOK Token ROI Calculator (Multi-Turn FinOps)

Most calculators wrongly assume 1 prompt = 1 API call and apply flat discounts to output tokens. We model real multi-step agentic tool loops, upstream KV-cache creation vs. read pricing, unindexed repo file-search waste (missing CLAUDE.md), and SWE-bench Pass@1 retry multipliers.
