DUPLEX: Agentic Dual-System Planning via LLM-Driven Information Extraction

📰 ArXiv cs.AI

DUPLEX is a neuro-symbolic architecture that combines LLMs with symbolic planning to improve reliability in long-horizon task planning

advanced Published 26 Mar 2026
Action Steps
  1. Identify the limitations of LLMs in long-horizon task planning, such as hallucination and logical inconsistency
  2. Design a dual-system architecture that separates information extraction from plan synthesis
  3. Implement schema-guided information extraction using LLMs to provide semantic flexibility
  4. Integrate the extracted information with symbolic planning to ensure rigorous plan synthesis
Who Needs to Know This
