In this post, we're sharing what we learned from running this hackathon, and what it suggests about the role humans will play when agents are doing the research experiments.

Questions about how reproducible AI research really is are older than the current AI wave. But these questions are exacerbated by scale. ICML 2026 received 23,918 submissions and accepted 6,352 papers, roughly double the previous year, continuing an exponential trend that is at least partly driven by AI agents making it faster to run experiments and write them up.

Reviewing capacity has not doubled along with it. Reviewers at most conferences are volunteers who may not have the time or expertise to fully review a paper. Here is a review of one accepted ICML 2026 spotlight paper, in the reviewer's own words:

"My low confidence score is because I did not check all the proofs carefully."

Note that this paper got strong scores and a spotlight. Keep it in mind, because we will come back to this exact paper later in the post, and to what happened when we finally did check the proofs carefully.

What has changed, though, is that the same technology driving the flood of submissions can also help us keep up with it. Coding agents like Claude Code, Codex, Cursor, and Pi can now read a paper, write the code, launch the experiments, and report back on what they found. Checking a paper carefully used to cost a reviewer a weekend; an agent can attempt it in an afternoon, in parallel, thousands of times over.
