Google's RRSI cuts overfitting in self-improving agents: up to 4.7-point gains on unseen tasks with ~30% fewer tokens
Google Cloud AI Research and several universities introduced RRSI, a method that stops self-optimizing agent harnesses from memorizing their test tasks. According to the paper, it gains up to 4.7 points on five unseen benchmarks and uses about 30% fewer runtime tokens than the unregularized version, with the underlying model frozen.
