It is very hard to keep up with multiple social media on multiple platforms. Allow me to share some old news. When ICML wrapped up, we used AI agents to review and replicate all 168 oral papers, including 105 full replications. The results are in this blog: sai.science/blog/how-muc...

How much science is verifiable? Results from replicating ICML 2026 oral papers
When ICML wrapped up, we used AI agents to review and replicate every oral paper to see what we can learn from actually verifying the science.

Open AI-assisted review tools could help researchers get better feedback, improve paper quality, and make the review process more scalable. But final publication decisions should remain under human oversight, via @chenhaotan.bsky.social openaireview.github.io/blog.html

AI-assisted Reviewing is Necessary and Should be Open

The blog actually discussed different types of reviews. If AI reviewing helps authors produce better science, I do not see why one needs to be so hostile against AI. It actually helps authors slow down to produce better-quality articles.

We also don't have good evaluations for AI-generated reviews yet. We're working on it and welcome collaborators. Feedback welcome, especially from conference organizers and journal editors who want to think seriously about the future of peer review.

chenhaotan.bsky.social @chenhaotan.bsky.social · 09/03/2026
There are two types of reviewing. Reviewing for quality (improving the work) — what Refine and OpenAIReview do — is very different from gatekeeping (accept/reject), which is what Stanford Agentic Reviewer targets. We think automating gatekeeping requires much more care.

Our progressive approach finds issues at 87% of locations flagged by Refine, for the price of a coffee per paper. @joehsu.bsky.social added a Claude skill making it essentially free for Claude subscribers.

3/7 The only intervention that can stabilize the system is improving review precision, the ability to distinguish good papers from weak ones. AI production tools lower submission costs; only AI review tools can raise the signal. That asymmetry is why we built OpenAIReview.

2/7 The review death spiral: more submissions → overloaded reviewers → noisier reviews → more random acceptance → even more submissions. Bergstrom & Gross already warned about this. AI production tools make it worse by lowering submission costs and pushing the system toward collapse faster.

Posted a very early stage draft with rock star collaborators. Key question: when we actually roll out AI tools, how do people use them? Do they just defer completely? Does it improve productivity and ability? We look in the medical setting of pulmonary embolisms paulgp.com/papers/Radio...
We study how radiologists use AI to diagnose pulmonary embolism (PE), tracking over 100,000
scans interpreted by nearly 400 radiologists during the staggered rollout of an FDA-approved
diagnostic platform. When AI flags PE, radiologists agree 84% of the time; when AI predicts no PE,
they agree 97%. Disagreement evolves substantially: radiologists initially reject AI-positive PEs in
30% of cases, dropping to 12% by year two. Despite a 16% increase in scan volume, diagnostic speed
remains stable while per-radiologist monthly volumes nearly double, with no change in patient
mortality—suggesting AI improves workflow without compromising outcomes. We document
significant heterogeneity in AI collaboration: some radiologists reject AI-flagged PEs half the time
while others accept nearly always; female radiologists are 6 percentage points less likely to override AI
than male radiologists. Moderate AI engagement is associated with the highest agreement, whereas
both low and high engagement show more disagreement. Follow-up imaging reveals that when
radiologists override AI to diagnose PE, 54% of subsequent scans show both agreeing on no PE
within 30 days.

I've often joked that as faculty I program in a high-level language called "graduate student". Having tried out Claude Code this morning, I (i) feel extremely at home, (ii) am realizing that research-by-graduate-student is perhaps the original vibe-coding. 1/2

I've seen this message and similar echos for other writing, and I want strongly push back on this narrative. It's not that you shouldn't use ChatGPT but that you shouldn't *use ChatGPT to write it for you*. ChatGPT—and AI in general—is not a monolith. How you use it matters.

It’s not about drugs. If it was, Trump wouldn’t have pardoned one of the largest narco traffickers in the world last month. It’s about oil and regime change. And they need a trial now to pretend that it isn’t. Especially to distract from his sinking under Epstein and skyrocketing healthcare costs.

Brown has canceled all remaining classes and exams for the Fall semester.
Email from Provost Francis J. Doyle
Subject: Update on Remaining Fall 2025 Classes and Exams

Dear Members of the Brown Community,

I'm writing to follow up on President Paxson's update from a short time ago to provide additional information on academic operations for the campus. Given the deeply tragic events that took place on our campus yesterday, all remaining undergraduate, graduate and medical classes, exams, and papers or projects for the Fall 2025 semester will not take place as scheduled. This choice was made out of our profound concern for all students, faculty and staff on our campus. In the immediate aftermath of these devastating events, we recognize that learning and assessment are significantly hindered in the short term and that many students and others will wish to depart campus. Students are free to leave if they are able. Students who remain will have access to on-campus services and support.
