What is AI subscriptions?
AI subscriptions are recurring-fee access products whose usable capacity depends on the provider, plan, workload, and applicable usage limits.
API-equivalent value estimates what a workload would cost at metered list prices; it is not provider production cost, a guaranteed token quota, or realized business value.
Compare plans using representative tasks, accepted outputs, interruptions, review effort, and the actual permitted access path.
