arXiv:2606.07874v1 Announce Type: new Abstract: LLMs-as-judges are the only way to evaluate safety at scale. Despite their importance, LLM-judges themselves are rarely evaluated beyond human agreement in simple, static benchmarks. We therefore investigate two under-explored but crucial properties of LLMs-as-judges: their susceptibility to relying on in context-information, and their steerability to differing safety definitions, which may not align with their internal safety priors. We evaluate the safety judging abilities of many generalist LLMs and safety-specific judges, and investigate the
The proliferation of LLMs and their increasing application as autonomous judges for critical tasks, particularly safety, necessitates rigorous evaluation methods and understanding of their inherent biases.
The reliability of LLMs-as-judges directly impacts the safety and ethical deployment of AI systems, potentially influencing regulatory frameworks and public trust in AI.
This research highlights the limitations and inherent biases in current LLM-judging paradigms, calling for more sophisticated evaluation metrics beyond simple human agreement.

- · Developers of custom, context-aware LLM-judges
- · Regulatory bodies focused on AI safety
- · Developers relying solely on 'off-the-shelf' LLM-judges for safety evaluation
- · Systems with rigid, non-contextual safety definitions
- · Benchmarks that lack nuance and contextual variability
Increased scrutiny and demand for transparency in how LLMs are used to evaluate AI safety and performance.
Development of new methodologies and frameworks for building 'contextual' and 'steerable' LLM-judges.
Potential for a 'meta-regulation' challenge, where AI models are used to evaluate AI models, raising questions about accountability and ultimate human oversight.
