AI agents leverage large language models to reason, strategize and execute complex tasks. They are ideal for automating a wide range of processes.
The development of LLM-based AI agent workflows has been an area of intense innovation, with the ReAct pattern being one of the earliest breakthroughs.
Task decomposition, multi-plan selection, external planner-aided planning, reflection and refinement, and memory-augmented planning are five key directions in LLM-agent planning.
Task decomposition is the process of breaking down a complex task into smaller, more manageable sub-tasks.
Multi-Plan Selection involves generating several possible plans and selecting the most promising one. This strategy is particularly useful when the optimal path is not immediately clear.
External Planner-Aided Planning involves leveraging external tools and systems to enhance an agent’s planning capabilities.
Reflection and Refinement allows agents to adapt and improve their future performance. This involves analyzing previous actions and outcomes to refine subsequent behavior.
Memory-Augmented Planning incorporates memory mechanisms to enhance an agent’s planning capabilities. Memory allows agents to retain and utilize past experiences, which leads to more effective and adaptable behavior.
Developers need to consider important factors such as hierarchical approach, parallel execution, loop, and conditional logic when implementing planning in AI agents.
Evaluating an agent’s planning capabilities is crucial to detect failures and ensure system reliability. Proper evaluation will ensure that the agent is able to achieve its goals and does not waste resources.
