Instruction

Large language models (LLMs) have achieved remarkable breakthroughs in natural language understanding and generation, but their logical reasoning capabilities remain a significant bottleneck. Logical reasoning is crucial for tasks requiring precise deduction, induction, or abduction, such as medical diagnosis, legal reasoning, and scientific hypothesis verification. However, LLMs often fail to handle complex logical problems with multiple premises and constraints, and they frequently produce self-contradictory responses across different questions. These limitations not only restrict the reliability of LLMs in complex problem-solving but also hinder their real-world applications.

In response to these emerging needs, we propose the workshop on Logical Reasoning of LLMs. This workshop will explore the challenges and opportunities for improving deduction, induction, and abduction capabilities of LLMs, implementing symbolic representation and reasoning via LLMs, avoiding logical contradictions across responses to multiple related questions, enhancing LLM reasoning by leveraging external logical solvers, and benchmarking LLM logical reasoning and consistencies. As LLMs continue to expand their role in AI research and applications, this workshop will serve as a platform to discuss and refine the methods for advancing logical reasoning within LLMs.

Topics

Topics of interest include, but are not limited to:

• • Deduction, Induction, and Abduction Capabilities of LLMs;

  • Symbolic Representation and Reasoning;

  • Avoiding Logical Contradictions Across Responses to Multiple Related Questions;

  • Enhancing LLM Reasoning by Leveraging External Logical Solvers;

  • Benchmarks and Evaluation for Logical Reasoning and Consistencies.

Important Dates

• First-Round Submission Deadline: February 20, 2026

• First-Round Notification of Acceptance: March 1, 2026

• Second-Round Submission Deadline: March 20, 2026

• Second-Round Notification of Acceptance: March 31, 2026

All deadlines are specified in Anywhere on Earth (AoE).

Note that first-round and second-round submissions are independent, that means (i) you can direct submit to second-round and (ii) first-round rejected papers can submit to second-round after revisions.

Submission Guidelines

We welcome two types of papers:

• Regular papers: Full-length research papers from 4 to 10 pages (excluding references and supplementary material);

• Tiny/Short papers: research/position papers from 2 to 4 pages (excluding references and supplementary material).

Papers should be submitted in the ICLR 2026 format (https://github.com/ICLR/Master-Template/raw/master/iclr2026.zip). 

The review process will be double-blinded; therefore, all identifying information, including author names, affiliations, and acknowledgments, must be excluded from submissions. We welcome both unpublished manuscripts and previously accepted or published papers, provided that their submission does not violate any dual-submission policies. The contributions are non-archival and all accepted papers will be made publicly available on OpenReview. 

There will be Oral Presentation Awards, Outstanding Paper Awards, and one Best Paper Award for accepted papers with outstanding quality.

Submission Site

The workshop uses OpenReview for paper submission and reviewing. The submission link is https://openreview.net/group?id=ICLR.cc/2026/Workshop/LLM_Reasoning.

Financial Assistance for Author Attendance

Our workshop is open to researchers, practitioners, and industry professionals interested in logical reasoning of large language models. There are no specific criteria or maximum number of attendees.

Authors of accepted papers in our workshop, including tiny/short papers, may be eligible for funding from ICLR to attend in person or virtually, but need to submit a separate application for Financial Assistance that is used by the DEI Chairs to make funding determinations for all ICLR contributors. This application for Finalcial Assistance will close on March 2nd, and more details can be found in https://iclr.cc/Conferences/2026/FinancialAssistance.

Reviewer Recruitment

We are actively seeking reviewers to join our program committee. If you are interested in contributing to the peer-review process, please contact Haoxuan Li at hxli@stu.pku.edu.cn.
