Many SWE-bench-Passing PRs would not be merged

https://metr.org/assets/images/many-swe-bench-passing-prs-would-not-be-merged-into-main/fig1_pass_rates_normalized.png
Researchers found that AI models' performance on benchmarks does not accurately reflect their real-world usefulness, with a significant gap between automated grader scores and maintainer review decisions. The study suggests that benchmarks should be viewed as one piece of evidence rather than decisive, and that more elicitation or human feedback is needed to accurately assess AI capabilities.

I didn't particularly enjoy the 1922 classic film, Häxan. I had to watch it in several shorter sittings in order to finish the entire film. I think the standards for entertainment have come a long way in the past 100+ years. What was, at the time, horrifying and bizarre seems today to be trite and bland. Maybe that's just a sign of the gradual decay of society... Anyways, I had ...
