Prüfstand — AI Testing Framework

Prüfstand is our framework for systematic testing of AI systems — prompt variations, model comparisons, quality scoring via LLM-as-a-Judge. Used for quality assurance of our own products.

Why systematic testing matters

AI models are non-deterministic. Without structured test setups, output quality silently drifts in production systems. Prüfstand lets us detect regressions before customers notice.
