AI TCO (Total Cost of Ownership)

定義

The comprehensive cost of an AI system over its full lifecycle, including model development, data preparation, infrastructure, licensing, monitoring, compliance, maintenance, and eventual decommissioning. TCO analysis often reveals that inference and compliance costs dwarf initial build costs.

AI ROI

The return on investment from an AI initiative, measured as the ratio of net benefit to total investment over a defined period. AI ROI is notoriously hard to quantify upfront but is increasingly demanded by CFOs; it spans hard savings (labour automation), soft gains (decision quality), and risk-adjusted value.

Inference Cost

The compute and financial cost of running a model to produce a single prediction or generated response. Inference cost is often the dominant AI operational expenditure at scale and is managed through model compression, caching, quantization, and batching strategies.

AI Business Case

A structured argument for an AI investment that quantifies expected benefits (revenue uplift, cost reduction, risk mitigation), costs (build, run, compliance), risks, and strategic alignment. A robust AI business case is the gateway to executive and board approval.
