A new paper from Transluce and UC Berkeley (Yaowen Ye, Jacob Steinhardt, Sarah Schwettmann, Cassidy Laidlaw) automates the discovery of datasets with surprising side effects (DSSEs) — training data that induces out-of-domain behavior shifts, like insecure code causing broad misalignment. Using LLM judges and search via evolution, RL, and subliminal learning, their pipeline produced 6,575 DSSEs across 8 behaviors, many generalizing across model families and sizes. Frontier models outperform humans at predicting side effects; the collection is open at dsse.transluce.org.
