AI FinOps: From Token Bills to Unit Economics

The provider invoice is accurate and still does not tell you what the AI system costs. It can report input tokens, output tokens, provisioned throughput and vector-search usage. It cannot tell you whether a customer case was resolved, whether an agent completed the intended workflow or whether a cheaper model merely moved cost into retries […]

The easiest evaluation to pass is the one that cannot stop a release. Many AI teams have evaluation notebooks, scorecards and dashboards. Far fewer have an explicit answer to a harder question: what evidence is required before a new model, prompt, retrieval index or tool definition is allowed to receive production traffic? Without that decision […]

Yet users are correcting more answers, an agent is opening the wrong records, and a workflow that used to finish in two tool calls now needs […]
