Classes
ChatSession
Chat session to make multi-turn send message request. Users can instantiate this using startChat method in GenerativeModel class. sendMessage method makes async call to get response of a chat message. sendMessageStream method makes async call to stream response of a chat message.
ChatSessionPreview
Chat session to make multi-turn send message request. sendMessage method makes async call to get response of a chat message. sendMessageStream method makes async call to stream response of a chat message.
ClientError
ClientError is thrown when http 4XX status is received. For details please refer to https://developer.mozilla.org/en-US/docs/Web/HTTP/Status#client_error_responses
GenerativeModel
Base class for generative models. NOTE: this class should not be instantiated directly. Use vertexai.getGenerativeModel() instead.
GenerativeModelPreview
Base class for generative models in preview. NOTE: this class should not be instantiated directly. Use vertexai.getGenerativeModel() instead.
GoogleAuthError
GoogleAuthError is thrown when there is authentication issue with the request
GoogleGenerativeAIError
GoogleGenerativeAIError is thrown when http response is not ok and status code is not 4XX For details please refer to https://developer.mozilla.org/en-US/docs/Web/HTTP/Status
VertexAI
Base class for authenticating to Vertex, creates the preview namespace. Users use getGenerativeModel method to start using Google's generative models in GA.

A FunctionDeclarationsTool is a piece of code that enables the system to interact with external systems to perform an action, or set of actions, outside of knowledge and scope of the model.
FunctionResponse
The result output of a FunctionCall that contains a string representing the FunctionDeclaration.name and a structured JSON object containing any output from the function call. It is used as context to the model.
FunctionResponsePart
A function response part of a conversation with the model.

Params used to call the generateContent method.
GenerateContentResponse
Response from the model supporting multiple candidates.
GenerateContentResult
Wrapper for respones from a generateContent request.
GenerationConfig
Configuration options for model generation and outputs.
GenerativeContentBlob
Raw media bytes sent directly in the request. Text should not be sent as raw bytes.
GetGenerativeModelParams
Params used to call the getGenerativeModel method.

Retrieval
Defines a retrieval tool that model can call to access external knowledge.
RetrievalTool
Defines a retrieval tool that model can call to access external knowledge.
SafetyRating
Safety rating corresponding to the generated content.
SafetySetting
Safety feedback for an entire request.
StartChatParams
Params to initiate a multiturn chat with the model via startChat.
StartChatSessionRequest
All params passed to initiate multiturn chat via startChat.
StreamGenerateContentResult
Wrapper for respones from a generateContent method when steam parameter is true.
TextPart
A text part of a conversation with the model.
UsageMetadata
Usage metadata about response(s).
VertexAISearch
Retrieve from Vertex AI Search datastore for grounding.
VertexInit
Params used to initialize the Vertex SDK.
Enums
BlockedReason
The reason why the reponse is blocked.
