Researchers have developed a new benchmark called ImpossibleRubrics to test the robustness of language model-generated rubrics. These rubrics are increasingly used for reinforcement learning and evaluations, but their reliability against adversarial inputs is not well understood. The benchmark focuses on "impossible tasks" where models are pressured to reach unsupported conclusions, and it includes verifiable oracle certificates to guide honest responses. Initial tests showed that even tailored rubrics were exploited frequently, highlighting a gap in rubric quality rather than task impossibility. AI
