Base interface for language model parameters. A subclass of BaseLanguageModel should have a constructor that takes in a parameter that extends this interface.

Properties

CallOptions: BaseLLMCallOptions
ParsedCallOptions: Omit<BaseLLMCallOptions, never>
caller: AsyncCaller

The async caller should be used by subclasses to make any async calls, which will thus benefit from the concurrency and retry logic.

maxTokens: number = 1700

Maximum limit on the total number of tokens used for both the input prompt and the generated response.

model: string = "general"

Model name to use.

temperature: number = 0.6

What sampling temperature to use. Should be a double number between 0 (inclusive) and 1 (inclusive).

verbose: boolean

Whether to print out response text.

apiKey?: string

Yandex Cloud Api Key for service account with the ai.languageModels.user role.

callbacks?: Callbacks
iamToken?: string

Yandex Cloud IAM token for service account with the ai.languageModels.user role.

metadata?: Record<string, unknown>
tags?: string[]

Accessors

Methods

  • This method takes an input and options, and returns a string. It converts the input to a prompt value and generates a result based on the prompt.

    Parameters

    Returns Promise<string>

    A string result based on the prompt.

  • This method is similar to call, but it's used for making predictions based on the input text.

    Parameters

    • text: string

      Input text for the prediction.

    • Optional options: string[] | BaseLLMCallOptions

      Options for the LLM call.

    • Optional callbacks: Callbacks

      Callbacks for the LLM call.

    Returns Promise<string>

    A prediction based on the input text.

  • Stream all output from a runnable, as reported to the callback system. This includes all inner runs of LLMs, Retrievers, Tools, etc. Output is streamed as Log objects, which include a list of jsonpatch ops that describe how the state of the run has changed in each step, and the final state of the run. The jsonpatch ops can be applied in order to construct state.

    Parameters

    Returns AsyncGenerator<RunLogPatch, any, unknown>

  • Default implementation of transform, which buffers input and then calls stream. Subclasses should override this method if they can start producing output while input is still being generated.

    Parameters

    Returns AsyncGenerator<string, any, unknown>
