What is PromptPerf?
PromptPerf lets you test a prompt across GPT-4o, GPT-4, and GPT-3.5 and compares results to your expected output using similarity scoring. Models change fast. Prompts break. This helps you stay ahead. Unlimited free runs. More models coming soon.
Problem
Users manually test and compare prompts across different AI models, leading to inefficient optimization and potential prompt failures as models update.
Solution
A web-based tool that lets users test and compare AI prompts results across multiple models (e.g., GPT-4o, GPT-4, GPT-3.5) with similarity scoring against expected outputs.
Customers
AI developers, data scientists, and machine learning engineers who need to ensure prompt reliability across evolving models.
Unique Features
Automated similarity scoring for prompt outputs, multi-model testing (with plans to expand), and unlimited free runs.
User Comments
