What does this tool do?
PromptPerf is a comparative AI model testing platform that allows users to systematically evaluate different AI models' performance on specific prompts. Unlike generic benchmarks, it enables users to test their exact use cases across multiple AI providers like ChatGPT, Claude, and Gemini. Users can input a sample prompt, define an expected output, and then see how different AI models perform in terms of accuracy, matching percentage, and cost-effectiveness.
