ICML’26 Workshop,
Seoul, South Korea,
Date: July 10 or 11, 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 the pitfalls of using LMs are and what guarantees 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.

Important Dates

Dual-submission and non-archival policy

Authors submitting papers rejected from other conferences, please ensure you do your utmost to address the comments given by the reviewers. The workshop is a non-archival venue and will not have official proceedings. Workshop submissions can be subsequently or concurrently submitted to other venues.

Reviewing policy

Double-blind reviewing
All submissions must be anonymized and may not contain any identifying information that may violate the double-blind reviewing policy. Submissions and reviews will not be public. Only accepted papers will be made public.

Reciprocal reviewing
Depending on the number of submissions, we may adopt a reciprocal reviewing process. For each submission, one reciprocal reviewer needs to be nominated who agrees to serve as a reviewer if reciprocal reviewing is implemented. Each nominated reviewer must have at least one relevant publication at a top venue and cannot be nominated as a reviewer for more than one submission.
