A recent discussion highlights a critical flaw in how Large Language Model (LLM) routing dashboards often report success rates. These dashboards typically measure success at the moment a model provides an answer, failing to account for outcomes that are only revealed days later through customer actions, downstream corrections, or system rejections. This leads to an "optimistically" skewed success rate, as failures are not yet accounted for. The author proposes running two success rate metrics in parallel: a provisional rate at answer time for alerting, and a final rate after an "attribution window" closes, which should be the sole basis for routing decisions. The gap between these two rates serves as a valuable signal for the reliability of the routing system. AI
