The system allows developers to define complex behavioral criteria through rubrics, which agents then learn to optimize in reverse, enabling controlled experimentation with goal-directed AI systems. This approach aims to provide a more rigorous and interpretable method for evaluating how AI agents pursue specified objectives.", "body_md": "x\nThis website requires javascript to properly function.
