Vertex AI supports a curated list of partner and open models as managed models. These models can be used with Vertex AI as a model as a service (MaaS) and are offered as a managed API. When you use a managed model, you continue to send your requests to Vertex AI endpoints. Managed models are serverless so there's no need to provision or manage infrastructure.
Managed models can be discovered using Model Garden. You can also deploy models using Model Garden. For more information, see Explore AI models in Model Garden.
