LLM API drift monitor exposes data collection flaws in Google and Mistral

By PulseAugur Editorial · [1 sources] ·

An open-source project called SEISMOGRAPH, designed to detect silent drift in third-party LLM APIs, has exposed a data collection issue. The project's creator discovered that the Google and Mistral AI API legs were not emitting data at their expected cadences. Specifically, the Google leg was emitting at only 61% of its usual rate, and the Mistral leg had frozen entirely, publishing no new data for an extended period. This issue was only revealed after the project implemented a denominator to track the number of samples and time bounds for data collection, highlighting a defect in previous reporting methods that relied solely on sample counts.
