+    "Let’s evaluate whether our current prompt migration has actually improved for the task of this judge. The original prompt, drawn from this [paper](https://arxiv.org/pdf/2306.05685), is designed to serve as a judge between two assistants’ answers. Conveniently, the paper provides a set of human-annotated ground truths, so we can measure how often the LLM judge agrees with the humans judgments.\n",

For context, the benchmark we’re using is a subset of MT-Bench, which features multi-turn conversations. In this example, we’re evaluating 200 conversation rows, each comparing the performance of different model pairs.\n",

Finally, after migrating and tuning our prompt specifically for GPT-4.1, the agreement climbs further, reaching 80% on turn 1 and 72% on turn 2, very close to matching the level of agreement seen between human annotators."
