AI evaluations, or 'evals,' are crucial for assessing the performance of advanced AI models like GPT-5.x, Claude, and Gemini, moving beyond traditional software testing methods. Unlike deterministic software, AI outputs are probabilistic and qualitative, requiring a more nuanced approach. Evals function similarly to a driving test, using curated real-world scenarios to measure an AI's output quality across multiple dimensions, such as accuracy, faithfulness, and tone, rather than expecting a single correct answer.
