Artificial intelligence device for language-based efficient agent utilization for navigation (lean) and method thereof

An artificial intelligence (AI) device, comprising:

• a memory configured to store agent based prompt information;
• and
• a controller configured to:
• receive a user query corresponding to a task,
• determine, by a first large language model (LLM) based component corresponding to a look-ahead planning phase, a shortlisted set of potential actions from a plurality of available actions available based on a current state of an interactive environment,
• generate, by a second LLM based component corresponding to an agile navigation phase, a textual reason for selecting an action from the shortlisted set of potential actions,
• determine, by the second LLM based component, a single optimal next action from the shortlisted set of potential actions based on the textual reason, and
• execute the single optimal next action to transition the interactive environment to a new state.

A non-transitory computer readable medium storing computer-executable instructions that when executed by a processor, cause the processor to perform the operations of:

• receiving a user query corresponding to a task;
• determining, by a first large language model (LLM) based component corresponding to a look-ahead planning phase, a shortlisted set of potential actions from a plurality of available actions available based on a current state of an interactive environment;
• generating, by a second LLM based component corresponding to an agile navigation phase, a textual reason for selecting an action from the shortlisted set of potential actions;
• determining, by the second LLM based component, a single optimal next action from the shortlisted set of potential actions based on the textual reason;
• and
• executing the single optimal next action to transition the interactive environment to a new state.
