Perform an unary online prediction request to a gRPC model server for Vertex first-party products and frameworks.

Parameters
Name	Description
request	DirectPredictRequest The request received from the client.
context	ServerCallContext The context of the server-side call handler being invoked.

Returns
Type	Description
TaskDirectPredictResponse	The response to send back to the client (wrapped by a task).

DirectRawPredict(DirectRawPredictRequest, ServerCallContext)

public virtual Task<DirectRawPredictResponse> DirectRawPredict(DirectRawPredictRequest request, ServerCallContext context)

Perform an unary online prediction request to a gRPC model server for custom containers.

RawPredict(RawPredictRequest, ServerCallContext)

public virtual Task<HttpBody> RawPredict(RawPredictRequest request, ServerCallContext context)

Perform an online prediction with an arbitrary HTTP payload.

The response includes the following HTTP headers:

• X-Vertex-AI-Endpoint-Id: ID of the [Endpoint][google.cloud.aiplatform.v1.Endpoint] that served this prediction.

• X-Vertex-AI-Deployed-Model-Id: ID of the Endpoint's [DeployedModel][google.cloud.aiplatform.v1.DeployedModel] that served this prediction.
