# ProductionVariantSummary
<a name="API_ProductionVariantSummary"></a>

Describes weight and capacities for a production variant associated with an endpoint. If you sent a request to the `UpdateEndpointWeightsAndCapacities` API and the endpoint status is `Updating`, you get different desired and current values.
