A NeurIPS 2026 Reviewer Reports Receiving Entirely LLM-Generated Rebuttals for an LLM-Generated Paper
An r/MachineLearning post from a NeurIPS 2026 reviewer (88 upvotes, 39 comments) describes a submission where both the paper and the author rebuttals appear machine-written, with 'Claude-speak everywhere,' and where the authors acknowledge LLM assistance. This is a new phase of a problem NeurIPS has been fighting all cycle: the conference desk-rejected hundreds of position-track papers flagged by AI detectors earlier in 2026, and its policy sanctions no LLM use during review outside a voluntary AI-assisted reviewing experiment running three arms (no assistance, open-ended assistance, structured assistance). The rebuttal stage was not previously the pressure point, and there is no detection or policy machinery aimed at it.
