Summary

First-time NeurIPS submitters often face confusion regarding OpenReview submission procedures, particularly concerning abstract, PDF, and code URL deadlines. For the abstract deadline, only the title and abstract are required; the PDF can be uploaded later, closer to the full paper submission deadline. While abstracts can be updated until the submission deadline, a proper abstract is necessary, as placeholders will lead to rejection. The author list, however, cannot be modified after the abstract deadline. For code URLs, they can typically be added when submitting the full paper, though the exact verification process for preventing late code pushes is less clear, often relying on timestamps and disclosure rather than strict platform enforcement. Some users have also reported technical errors during the submission process, specifically "Error: Cannot read properties of undefined (reading 'id')".

Key takeaway

For AI Scientists and Students preparing a NeurIPS submission, ensure your title and abstract are finalized and properly submitted by the abstract deadline, as placeholders are rejected and author lists become locked. You can upload your full paper PDF and add code URLs later, but be mindful that code push verification often relies on transparent timestamps. If you encounter submission errors like "Cannot read properties of undefined (reading 'id')", be aware that others have experienced similar technical issues.

Key insights

NeurIPS submissions require a proper abstract by the deadline, with PDFs and code URLs added later.

Principles

• Author lists are immutable post-abstract deadline.
• Placeholders for abstracts are rejected.
• Code push verification relies on timestamps.

In practice

• Submit a complete title and abstract by the abstract deadline.
• Upload your paper PDF closer to the full submission deadline.
• Ensure code repositories have clear timestamps for verification.
