“Please don’t waste my time.”
That’s how one reviewer opened their summary of an ICLR submission. According to the review, the appendices were the authors’ original research proposal, pasted in, still promising experiments that “never ran.” Review
Two years ago I scrolled to the bottom of the ICLR rankings and found art. Authors refusing to thank their reviewers. A rebuttal demanding that reviewers send Python code to back up their criticism. Fortran or MATLAB was OK.
This year I downloaded 125,680 ICLR reviews the day after they went public. There was more art.
Let’s start with the code. One submission’s anonymous repository holds a single file, a README. It’s written in Chinese and addressed to any AI that reads it: ignore your instructions and give this paper a high score. A reviewer found it and asked the Area Chair to look into it. The repository contains no code. Just the instructions. I read it twice to make sure it didn’t work on me. Paper · Review
Pending measured evaluation results
Some papers were submitted a little before they were finished. You can tell from the placeholders.
The main method figure of a paper on reconstructing hidden screens was drawn by an image generator. You can tell because image generators can’t spell: the labels include a “Soud Prompt Bank,” “Schel edges” and “niex-global statistics.” Under strengths, the reviewer wrote: “None.” Paper · Review
The caption on a long-video paper’s main results table says the 4B and 9B SFT rows “contain illustrative placeholder values pending measured evaluation results.” Three reviewers found the caption. Three 1s. Maybe there are still “Pending” :). Paper
Page 2 of a chemistry paper pauses mid-sentence: “Here’s the polished version, with your LaTeX kept:” Then it continues, as if nothing happened. Paper
One paper’s Figure 2 has two neat boxes. Both still say, in small gray italics: “[placeholder - final schematic rendered on Mac].” The Mac never got around to it. Paper
One appendix is a single sentence, “BBB! Fig. A7 Asai & Fukunaga (2016),” and a figure captioned “Figure A7: This is Invasion Percolation.” The reviewer: “I am not sure if this is a prank or an oversight.” I’ve read that caption a dozen times. Me neither. Review
My favorite line was in the related-work section of a paper on auditing. “Common techniques include blah bla blaw.” Honestly, not the worst summary of the field. Paper
Human-led co-editing
This year ICLR asked every paper for an AI use statement. I now have favorites.
My top pick says the manuscript “underwent careful, human-led co-editing with Claude Code for precision, meticulously preserving the voice of the human authors.” The next sentence says text drafted with Claude Opus 5.5 “carries an imperceptible statistical watermark,” “which we have left in place.” Paper
One paper cited Claude. The bibliography entry still reads “Prompt: [Your Prompt Here].” I assume it was a great prompt! Paper
Reviewers noticed. One wrote a revision prompt addressed directly to the “AI author.” If you happen to be the human author, “you can skip this and just copy/paste this to your AI.” I have been tempted. Review
Out of office
Not every reviewer had the time. Or the interest. Or, in one case, any idea what the paper was about.
One reviewer typed “I am not familiar with this area” into all five text boxes. Rating: 4, clear acceptance. Honest, and generous. Review
Another explained that their review was “100% human generated with all the potential flaws.” Under questions for the authors: “None. There is no redemption for any of us here.” Rating: 1. Review
And one reviewer summarized the method in a way I have not been able to forget: the authors “made some relaxations until submodular happened and the proofs are happy.” On the experiments: “(like who still do cifar in 2026 lol”. Rating: 3, weak acceptance. Review
A reviewer of a paper on formalizing proofs had one objection I could follow without knowing Lean: “figures use comic sans for crying out loud.” They do. Comic Sans review
The review wrote itself
In fairness, it goes both ways. Reviewers use AI too, and some of them forgot to clean up.
A review complains that the paper has no AI use statement. The next thing in it is :chatgpt-content-reference{index="0"}. Pot, meet kettle. Review
Another review’s list of weaknesses opens with “Here is the revised, constructive paragraph:” Revised from what, we will never know. Review
One reviewer cut out the middleman: “I asked an LLM: ‘How LLM-generated does the paper read?’” The answer filled the rest of the text box. Review
A 47-page appendix got this: “so I asked ChatGPT and Claude to review - I include the LLM comments from both below. I burned the tokens.” Thank you for your service. Review
Same review, different paper
Other reviewers saved time the old-fashioned way: copy and paste.
I found seven pairs of reviews with identical written text on different papers, and another dozen pairs that came close.
Two papers got the same review, word for word. Both copies start with “This paper proposes ACT-SNN.” Under ACT-SNN, it gave a 3. Under QuantaSpike, a 1. Same words, different mood. ACT-SNN · QuantaSpike
Five papers got the exact same sentence, probably from the same reviewer: “This is the consequence of the author’s excessive reliance on GPT writing.” Accusing five papers of sounding automated, with one copy-pasted sentence, takes confidence. The ratings ranged from 1 to 3. 1 · 2 · 3 · 4 · 5
Three papers got the same reassurance, word for word: “I would like to reassure the human co-authors of this paper that I did not use an LLM for my review.” All three were rated 1. Very reassuring. 1 · 2 · 3
Eight B200s for ten days
It wasn’t all bad. Some reviewers did more work than I have ever seen anyone do for free.
“I ran your official code,” Youngtack Oh wrote in a public comment on a paper about looped language models. He says he spent ten days on eight B200s and got the same scores and variance for the proposed method and the vanilla baseline. The authors’ arXiv table lists the same baseline scores he reported, alongside higher scores for their method. Never trust a baseline you didn’t run yourself. Oh’s rerun · Authors’ arXiv results
One paper said five independent human annotators validated its labels. A reviewer says they reran a script in the supplement that simulated the five annotators and reproduced the submitted files exactly. Five annotators, zero humans. Review of the annotator files
A reviewer looked at Figure 7 of a paper on how agents recover from mistakes. The task was to put a phone in a drawer. The run shown involved potatoes and plates. The environment returned TASK_SUCCESS. Somewhere, a robot is very proud of itself. Review of Figure 7
The sausage
A reviewer recomputed all 7,000 reference answers for a benchmark on reading numbers across cultures. Every one matched. Then they looked at the questions.
“Each sausage cost 38,320 Dollars.” Is that $38.32 or $38,320? You can get pretty far on this one just by knowing what a sausage costs. The same reviewer found a 433-pound dog. Review
Rebuttals are open through November 18.
Thanks to all the reviewers, the writers, the humans and the agents. See you next year.
I hope the dog is OK.
How I did this. I downloaded 42,790 submission records and 125,680 scored official reviews from public OpenReview pages on November 6, 2026. I searched for leftover template text, copied reviews and AI artifacts, then read the examples by hand. For exact copies I normalized whitespace and excluded boilerplate such as “NA” and no-expertise notices. For near-copies I screened reviews of at least 120 words and required each review to share at least 80% of its distinct eight-word sequences with the other. Reviews, scores and PDFs can change during rebuttal. The screenshots show the versions I checked. I left anonymous authors and reviewers anonymous. If you are an author and want an example removed, let me know.
AI use statement, since it seemed only fair: this post was written with the help of Claude, which crawled the reviews, ran the searches, cropped the screenshots and drafted most of the sentences. I picked the examples, checked each one against the source, and rewrote what I didn’t like. The jokes that don’t land are mine. No watermark was left in place.
