 If the new allocations fit on the current machine learning nodes, they are immediately started.
 If more resource capacity is needed for creating new model allocations, then your machine learning node will be scaled up if machine learning autoscaling is enabled to provide enough resources for the new allocation.
 The number of model allocations can be scaled down to 0.
 They cannot be scaled up to more than 32 allocations, unless you explicitly set the maximum number of allocations to more.

 When you create inference endpoints on Serverless using Kibana, adaptive allocations are automatically turned on, and there is no option to disable them.
