Every ABBYY Vantage tenant requires a subscription that determines which features, skills, and processing capacity are available. Your subscription determines: * The period during which features are available * The number of pages that can be processed during the subscription period * The available skills * The available feature set — depending on the subscription type, Advanced Designer may be available The number of pages processed by various skills is tracked by counters tied to your subscription. ## Entitlements outside the subscription Some capabilities are provided through a separately contracted entitlement rather than through your subscription's counters. **ABBYY Phoenix Plus**, the ABBYY-supplied LLM endpoint, works this way. Consumption of an entitlement like this: * Is metered by ABBYY separately from your page counters. It does not draw down your page allowance, and the pages a document consumes are counted as normal. * Is not part of your license and does not appear in subscription statistics. * Is not currently shown in the Vantage interface. For consumption figures, contact your ABBYY account team. * Is unaffected by license changes. Uploading a new license, renewing, or changing a subscription does not turn an entitlement on or off. To obtain or change an entitlement, contact your ABBYY account team. For what ABBYY Phoenix Plus is, see [LLMs in ABBYY Vantage](/vantage/documentation/llms/llms).
