Exporting virtual machine data doesn’t give people any privileged access to Meta infrastructure or to other people’s data.” Unlike with the average laptop, however, the data potentially reveals some interesting things about how Meta’s new AI platform functions. We seem to be entering into an AI agent renaissance.

The system achieved superhuman performance in each instance, demonstrating the generality of this method. In the future, the researchers wa

alar RMs. And the gains survive RLHF. When used as the training-time reward, DRM improves downstream policy performance over scalar reward baselines, showing that the benefit is not limited to offline RM benchmarks. The takeaway: Reward modeling may lose something important when it compresses every human judgment into one number. “Everyone thinks this is average” and “people strongly disagree about this” should not look identical to a Reward Model. DRM makes that difference visible — and usable.

The trade-off is a growing coverage gap: a newer model may retrieve a genuinely relevant document that was never included in the original judgment pool, yet conventional nDCG will not recognize it. As retrieval systems become more capable and explore parts of a corpus that earlier systems did not, benchmarks can increasingly reflect just what previo
