.prompt(creator: nil, **args) ⇒ String

Returns the LLM prompt for the task.

Parameters:

  • creator (Object, nil) (defaults to: nil) —

    The creator of the task (polymorphic association), optional

  • args (Hash) —

    Additional arguments to pass to the instance of the task that is created.

.run(creator: nil, available_model_tools: [], llm_model_key: nil, images: [], files: [], **args) ⇒ Raif::Task?

The primary interface for running a task. It will hit the LLM with the task’s prompt and system prompt and return a Raif::Task object. It will also create a new Raif::ModelCompletion record.

Parameters:

  • creator (Object, nil) (defaults to: nil) —

    The creator of the task (polymorphic association), optional

  • available_model_tools (Array<Class>) (defaults to: []) —

    Optional array of model tool classes that will be provided to the LLM for it to invoke.

  • llm_model_key (Symbol, String) (defaults to: nil) —

    Optional key for the LLM model to use. If blank, Raif.config.default_llm_model_key will be used.

  • images (Array) (defaults to: []) —

    Optional array of Raif::ModelImageInput objects to include with the prompt.

  • files (Array) (defaults to: []) —

    Optional array of Raif::ModelFileInput objects to include with the prompt.

  • args (Hash) —

    Additional arguments to pass to the instance of the task that is created.

Returns:

  • (Raif::Task, nil) —

    The task instance that was created and run.
