Vertex AI managed models for MaaS
Vertex AI supports a curated list of partner and open models as managedmodels. These models can be used withVertex AI as amodel as a service (MaaS) and are offered as a managed API. When you use amanaged model, you continue to send your requests to Vertex AIendpoints. Managed models are serverless so there's no need to provision ormanage infrastructure.
Managed models can be discovered using Model Garden. You can alsodeploy models using Model Garden. For more information, seeExplore AImodels inModel Garden.
