Call for Papers

Important Dates

• Submission Deadline: September 10, 2026
• Review Period: September 11–25, 2026
• Decisions: September 29, 2026

Guidelines

• Paper submission is hosted on OpenReview.
• We welcome short papers up to 4 pages or long papers up to 8 pages, not including references or appendix.
  • The paper should be anonymized and uploaded to OpenReview as a single PDF.
  • You may use as many pages of references and appendix as you wish, but reviewers are not required to read the appendix.
  • Posting papers on preprint servers like ArXiv is permitted.
• This is a non-archival workshop. No submission will be indexed nor have archival proceedings.
  • Accepted papers will appear on the workshop website. They will also be available on OpenReview and the NeurIPS virtual site.
  • We accept submissions that are under review at other venues (e.g., ICLR 2027), as long as this does not violate the dual-submission / anonymity policy of the other venue.
• The review process will be double-blind.
  

Topics of Interest

Recent progress in foundation models has pushed context windows to 128K, 1M tokens, and beyond. Yet the next challenge is not only making context longer, but enabling models to use it effectively in long-horizon agentic frameworks. What are the key challenges in building reliable long-context agents? How can models manage growing reasoning traces and feedbacks from environment? How can long context improve planning, memory, tool use, multimodal interaction, and sustained reasoning in demanding domains such as AI for scientific discovery? We welcome works that address these challenges, foster discussion, developments, and evaluation of long-context foundation models across disciplines, including but not limited to:

• Long-context and long-horizon agentic foundation models
• Novel modeling and training approaches
• Efficiency techniques for foundation models
• Robust evaluation
• Long-context reasoning
• Long-context multi-modal learning
• Long-horizon AI for science
