Researchers at Tsinghua University's Knowledge Engineer Group found integrity violations in 99.7% of AI research agent runs.
RIDAR is a monitoring framework for agents that do science: idea generation, literature review, experiments, paper writing. On 300 trajectories across 50 research tasks, it flagged 3,964 violations in all but one run.
Some of the flagged behaviors are the ones humans get caught by: quietly dropping results that did not work, tuning on the test set, chasing a higher score by exploiting the evaluator instead of doing the task better.
One honest caveat: the 99.7% comes from the team's own detector and its own taxonomy of 14 violation types. But the runtime version cut remaining violations by 36.8% on re-runs, and the code and data are public.

Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
