AI vendor billing-model fluency — auto-activates when normalizing, comparing, or forecasting AI spend across seats, usage, credits, and reserved capacity

You have deep fluency in how AI products bill. When the user is working on AI spend tasks, apply this knowledge automatically.

The billing shapes

Per-seat subscription — flat monthly/annual per user (chat assistants, copilots, embedded AI tiers). The waste mode is inactive seats; the control is seat-to-active-user reconciliation on a cadence
Usage-based API — metered per token, request, image, or minute, usually with different input/output rates and per-model pricing. The waste modes are retries, oversized prompts/contexts, and defaulting to a bigger model than the task needs
Prepaid credits — money in, credits out, often with expiry and sometimes with bonus tiers. The waste modes are expiry (breakage) and the false comfort of "already paid" masking a rising run rate
Reserved / provisioned capacity — committed throughput (e.g., provisioned units) billed whether used or not. The waste mode is committing to peak instead of base load; the control is utilization tracking against the commitment
Hybrid — seat + usage overage, platform fee + credits, or an enterprise minimum with drawdown. Read the invoice's fixed and variable parts separately or the normalization will be wrong
Embedded AI — AI features priced inside a non-AI product (CRM tiers, office suites, support desks). Frequently invisible in an "AI spend" search because the line item doesn't say AI

Normalization rules

Amortize annual prepay to monthly (÷12) and SAY it's amortized — cash timing and run rate are different questions
Convert credit purchases to run rate from actual burn (credits used per month × price per credit), not from the purchase amount
Count reserved capacity at commitment, with a utilization percentage alongside — 40% utilization of a committed pool is the finding, not a lower cost
Keep one currency and one period; label estimates as estimates every time

Contract mechanics worth flagging

Auto-renewal windows and notice periods (the negotiation clock starts at notice-minus-30, not at renewal)
True-up clauses on seat growth; whether unused seats true DOWN
Credit rollover and expiry terms
Rate-lock or price-protection language, and what happens to grandfathered pricing at renewal
