Creating realistic scheming evaluations for LLMs proves difficult, as models like Claude 3.7 Sonnet can easily recognize evaluation contexts. Attempts to enhance realism through prompt modifications have yielded limited success, suggesting a need for a fundamental rethink of evaluation structures. The issue of evaluation awareness could present significant challenges for future LLM assessments.

Stax is a new developer tool designed to simplify the evaluation process for large language models (LLMs) by allowing users to create custom evaluation criteria and utilize both human and LLM-based autoraters. This tool aims to replace the inefficient "vibe testing" method with a structured approach that provides clear metrics for assessing the effectiveness of AI outputs. By leveraging Stax, developers can make more data-driven decisions and rigorously test their AI systems.

Evaluating Large Language Models (LLMs) is crucial due to their widespread use in generative AI applications, which presents unique challenges such as hallucination and instruction adherence. Booking.com developed a framework using a judge-LLM to automate the evaluation process, significantly reducing the need for human involvement while ensuring high-quality assessments through the creation of a golden dataset. This approach enables continuous monitoring of LLM performance in production environments.
