Constructors

constructor

new AbstractGoogleLLMConnection<MessageType, AuthOptions>(fields, caller, client, streaming?): AbstractGoogleLLMConnection<MessageType, AuthOptions>
Type Parameters
- MessageType
- AuthOptions
Parameters
- fields: undefined | GoogleAIBaseLLMInput<AuthOptions>
- caller: AsyncCaller
- client: GoogleAbstractedClient
- Optional streaming: boolean
Returns AbstractGoogleLLMConnection<MessageType, AuthOptions>
Inherited from GoogleAIConnection.constructor

Properties

apiVersion

apiVersion: string = "v1"

The version of the API functions. Part of the path.

caller

caller: AsyncCaller

client

client: GoogleAbstractedClient

endpoint

endpoint: string = "us-central1-aiplatform.googleapis.com"

Hostname for the API call (if this is running on GCP)

location

location: string = "us-central1"
