What is Agentic AI Planning Pattern? - Analytics Vidhya

This article explores Agentic AI Planning Patterns, crucial for structuring complex AI tasks. These patterns enable AI to break down large goals into smaller, manageable sub-goals, adapting to feedback and changes. We'll examine two decomposition approaches: Decomposition-First (pre-planning for stable environments) and Interleaved (flexible, adaptive planning for dynamic situations).

The ReAct framework combines reasoning and acting for iterative problem-solving. We'll also discuss ReWOO, a more efficient architecture minimizing redundant observations and prioritizing planned action sequences. This optimizes complex task completion.

Agentic AI Planning: A High-Level View

The Agentic AI Planning Pattern uses a structured loop: planning, task generation, execution, and replanning. This iterative process allows AI to adjust its approach based on results, improving adaptability. Key components include: planning (initial strategy), task generation (breaking down the problem), single-task agents (executing sub-goals using methods like ReAct or ReWOO), replanning (adjusting based on results), and iteration (repeating the process).

Illustrative Example: Image Understanding

This example demonstrates how the pattern works in image understanding. The goal is to describe an image and count objects. The agent breaks this down into sub-goals (object detection, classification, caption generation). It uses pre-trained models as tools, combines results, and evaluates its output before presenting the final answer.

Task Decomposition Strategies

Two approaches exist: Decomposition-First (complete decomposition before execution, suitable for stable environments) and Interleaved (concurrent decomposition and execution, adapting to dynamic environments).

ReAct: Reasoning and Acting

ReAct combines reasoning and acting in a loop. The model reasons, takes action, observes the result, and incorporates that into its next reasoning step. This iterative process allows for adaptation and complex problem-solving.

ReAct Implementation (OpenAI API and httpx)

This section would detail code using the OpenAI API and httpx library to implement the ReAct pattern, including custom actions (Wikipedia search, calculations, etc.). (Code example omitted for brevity; see linked article for details).

ReAct with LangChain

This section would show how to build a tool-augmented agent using LangChain and OpenAI's GPT models, integrating custom tools (e.g., web search). (Code example omitted for brevity; see linked article for details).

ReWOO: Reasoning Without Observation

ReWOO improves efficiency by generating a complete plan upfront. A planner creates the plan, a worker executes it, and a solver synthesizes the final answer. This reduces redundant LLM calls.

ReWOO vs. Observation-Based Reasoning

ReWOO's structured approach reduces prompt redundancy compared to observation-dependent reasoning, improving efficiency and scalability.

ReWOO Code Example (LangGraph)

This section would provide a code example using LangGraph to implement the ReWOO architecture. (Code example omitted for brevity; see linked article for details). Illustrative diagrams are included.

Benefits and Limitations

Agentic AI planning offers flexibility and adaptability but can be unpredictable and less consistent than simpler methods.

Conclusion

Agentic AI planning patterns are essential for building sophisticated AI systems. ReAct and ReWOO represent advancements in this area, improving efficiency and adaptability.
