What is Agentic Behavior?

Before we dive into how, let’s define what we mean by “agentic” LLMs:

Goal-oriented: Agentic LLMs would actively pursue goals, either intrinsically defined or given by users.
Proactive: They would take initiative rather than solely reacting to prompts.
Autonomous: They would exhibit independent decision-making in the pursuit of goals, demonstrating some degree of self-direction.
World-aware: They would be able to perceive and interact with real-world environments (or sufficiently complex simulations) to gather information, carry out actions, and update their understanding.

How to Enhance Agency in LLMs

Embodiment and Grounding

Connecting LLMs to sensory inputs and giving them the ability to act upon the world (whether physical or simulated) is crucial. This allows them to learn through experience and develop context-dependent actions.
Research in robotics and embodied AI would be essential for this direction.

Multimodal Learning

Currently, LLMs are primarily text-based. Integrating the ability to process and generate images, video, and audio would significantly expand their ability to understand and interact with a wider range of information and tasks.

Goal-directed Reinforcement Learning

Reinforcement learning (RL) frameworks, where the LLM learns through trial and error guided by rewards, can help develop goal-seeking behaviors.
However, defining appropriate reward functions becomes a complex, potentially dangerous problem in itself.

Planning and Meta-Learning

The ability to break down complex goals into sub-tasks and plan sequences of actions would be necessary for complex agency.
Meta-learning (learning to learn) would help LLMs adapt to new tasks and goals more quickly.

Enhanced Interaction and Communication Capabilities

Natural Language Understanding and Generation: Advancements in understanding nuances, contexts, sarcasm, and complex instructions in natural language are vital. This includes generating responses that are not only relevant and coherent but also exhibit empathy and adaptability to the user’s emotional state.
