  • A static factory method that creates an instance of TaskExecutionChain. It constructs a prompt template for task execution, which is then used to create a new instance of TaskExecutionChain. The prompt template instructs an AI to perform a task based on a given objective, taking into account previously completed tasks.

    Parameters

    • fields: Omit<LLMChainInput<string, any>, "prompt">

      An object of type LLMChainInput, excluding the "prompt" field.

    Returns LLMChain<string, any>

    An instance of LLMChain.
