    Interface BaseLanguageModelParams

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

    interface BaseLanguageModelParams {
        cache?: boolean | BaseCache<Generation[]>;
        callbackManager?: CallbackManager;
        callbacks?: Callbacks;
        maxConcurrency?: number;
        maxRetries?: number;
        metadata?: Record<string, unknown>;
        onFailedAttempt?: FailedAttemptHandler;
        tags?: string[];
        verbose?: boolean;
    }

    cache?: boolean | BaseCache<Generation[]>
    callbackManager?: CallbackManager

    Use callbacks instead

    callbacks?: Callbacks
    maxConcurrency?: number

    The maximum number of concurrent calls that can be made. Defaults to Infinity, which means no limit.

    maxRetries?: number

    The maximum number of retries that can be made for a single call, with an exponential backoff between each attempt. Defaults to 6.

    metadata?: Record<string, unknown>
    onFailedAttempt?: FailedAttemptHandler

    Custom handler to handle failed attempts. Takes the originally thrown error object as input, and should itself throw an error if the input error is not retryable.

    tags?: string[]
    verbose?: boolean
