PromptPerf

Automates prompt evaluation and regression testing across models

PlatformWebfreemiumglobal

PromptPerf automates prompt evaluation by testing a single prompt against multiple OpenAI models and comparing results to an expected output using semantic similarity scoring, helping teams catch when model updates silently change prompt behavior. It's aimed at prompt engineers and AI product teams who need to spot regressions as models evolve.
