A study of metering for inference services argues that under batched serving no per-request meter can be simultaneously additive, independent of co-resident traffic, and exactly cost-reflective. Its proposed architecture uses reference inference units and occupancy-indexed ratings, which limit statement energy error to 9 percent under measured traffic, compared with 70.5 percent under fixed-occupancy rating. Tenant mispricing falls from 7.36 times under flat token counting to 1.06 times after occupancy-based reconciliation. For a buyer, that means a low token price is not a complete price: the metering method decides whether the bill tracks the work done under sharing.",

Second, does its metering reflect sharing, since flat token counting misprices tenants when requests share hardware? Third, can it demonstrate the demand and cost structure behind its prices, since a platform that cannot show its controls or its metering leaves the buyer to discover the real bill after deployment?",
