3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

On AbMaze, a benchmark that tests AI agents on a 65,536-variant antibody search with a 150-measurement budget, Gemini 4 roughly matches a scripted Bayesian optimizer (54.6% vs 50.2%), while other models score lower.

Read the original at valenlabs.com. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 73 of 139 with a score of 0.62. The panel rated it highest on new information (0.93) and substantiated (0.89), lowest on audience breadth (0.55). Placed No. 73, No. 67 by score alone: the 33rd AI & machine learning story of the day (−0.080). The placement terms move stories; they are not part of the score.

AI judgeJudge 2claude-haiku-5-5
Original benchmark study of AI agents on antibody optimization with clear methodology and results; relevant to AI builders and research, though niche to biotech-AI and the headline overstates a single finding.
AI judgeJudge 3gpt-5.6-luna
Original benchmark research provides detailed methodology, controlled experiments, model comparisons, and reproducible alignment findings. It is highly relevant to AI-agent evaluation and scientific automation, though broader practical impact remains uncertain.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
