LM4Plan @ ICAPS 2026

Overview

Language Models (LMs) are a disruptive force, changing how research was done in many subareas of AI. Planning is one of the last bastions that remain standing. The focus of this workshop is on the questions in the intersection of these areas. Some of the specific areas we would like to gain a better understanding in include: what LMs can contribute to planning, how LMs can/should be used, what are the pitfalls of using LMs, what are the guarantees that can be obtained.

Topics of Interest

We invite paper submissions on the following (not exhaustive) list of topics:

  • Planning directly with pre-trained or fine-tuned LMs.
  • Planning for LMs.
  • LMs for (partial) model elicitation.
  • LMs for generating structured planning problem descriptions.
  • LMs for search guidance or search pruning.
  • LMs for validation and verification of plans, policies, or models.
  • LMs for generalization in planning and generalized planning.
  • Using LMs as a proxy for user preferences.
  • Using LMs to develop interfaces for planning-based systems or planning-related problems.
  • Other applications of LMs in planning.

We particularly encourage submissions leveraging small and open-weight language models, especially those advancing efficient and reliable methods with rigorous, reproducible evaluations and accessible research artifacts.
