public static interface PredictionServiceGrpc.AsyncService

A service for online predictions and explanations.

Methods

chatCompletions(ChatCompletionsRequest request, StreamObserver<HttpBody> responseObserver)

public default void chatCompletions(ChatCompletionsRequest request, StreamObserver<HttpBody> responseObserver)

Exposes an OpenAI-compatible endpoint for chat completions.

Parameters
Name	Description
request	ChatCompletionsRequest
responseObserver	io.grpc.stub.StreamObserver<com.google.api.HttpBody>

countTokens(CountTokensRequest request, StreamObserver<CountTokensResponse> responseObserver)

public default void countTokens(CountTokensRequest request, StreamObserver<CountTokensResponse> responseObserver)

Perform a token counting.

Parameters
Name	Description
request	CountTokensRequest
responseObserver	io.grpc.stub.StreamObserver<CountTokensResponse>

directPredict(DirectPredictRequest request, StreamObserver<DirectPredictResponse> responseObserver)

public default void directPredict(DirectPredictRequest request, StreamObserver<DirectPredictResponse> responseObserver)

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

Parameters
Name	Description
request	DirectPredictRequest
responseObserver	io.grpc.stub.StreamObserver<DirectPredictResponse>

directRawPredict(DirectRawPredictRequest request, StreamObserver<DirectRawPredictResponse> responseObserver)

public default void directRawPredict(DirectRawPredictRequest request, StreamObserver<DirectRawPredictResponse> responseObserver)

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

Parameters
Name	Description
request	DirectRawPredictRequest
responseObserver	io.grpc.stub.StreamObserver<DirectRawPredictResponse>

explain(ExplainRequest request, StreamObserver<ExplainResponse> responseObserver)

public default void explain(ExplainRequest request, StreamObserver<ExplainResponse> responseObserver)

Perform an online explanation. If deployed_model_id is specified, the corresponding DeployModel must have explanation_spec populated. If deployed_model_id is not specified, all DeployedModels must have explanation_spec populated.

Parameters
Name	Description
request	ExplainRequest
responseObserver	io.grpc.stub.StreamObserver<ExplainResponse>

generateContent(GenerateContentRequest request, StreamObserver<GenerateContentResponse> responseObserver)

public default void generateContent(GenerateContentRequest request, StreamObserver<GenerateContentResponse> responseObserver)

Generate content with multimodal inputs.

Parameters
Name	Description
request	GenerateContentRequest
responseObserver	io.grpc.stub.StreamObserver<GenerateContentResponse>

predict(PredictRequest request, StreamObserver<PredictResponse> responseObserver)

public default void predict(PredictRequest request, StreamObserver<PredictResponse> responseObserver)

Perform an online prediction.

Parameters
Name	Description
request	PredictRequest
responseObserver	io.grpc.stub.StreamObserver<PredictResponse>

rawPredict(RawPredictRequest request, StreamObserver<HttpBody> responseObserver)

public default void rawPredict(RawPredictRequest request, StreamObserver<HttpBody> responseObserver)

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 that served this prediction.
• X-Vertex-AI-Deployed-Model-Id: ID of the Endpoint's DeployedModel that served this prediction.

Parameters
Name	Description
request	RawPredictRequest
responseObserver	io.grpc.stub.StreamObserver<com.google.api.HttpBody>

serverStreamingPredict(StreamingPredictRequest request, StreamObserver<StreamingPredictResponse> responseObserver)

public default void serverStreamingPredict(StreamingPredictRequest request, StreamObserver<StreamingPredictResponse> responseObserver)

Perform a server-side streaming online prediction request for Vertex LLM streaming.

Parameters
Name	Description
request	StreamingPredictRequest
