A software engineering team experienced a significant drop in their automated regression evaluation scores due to silent model updates from a third-party provider. The team discovered that the model they were using was being updated behind a floating alias, causing their evaluation harness to test different versions without realizing it. To resolve this, they implemented a gateway solution that enforces the use of exact, dated model strings and added monitoring to detect any changes in the underlying model. AI
