## About

LLM models are changing fast -> Gemini 1.0 and GPT-4 gets quietly updated, models get deprecated, and the same prompt suddenly gives different results.

PromptPerf helps you stay ahead.
It lets you test a single prompt against multiple OpenAI models and compares the results to your expected output using semantic similarity scoring.

Perfect for:

- Prompt engineers, AI devs, and product teams

- Quickly validating prompt reliability

- Spotting regressions as models evolve

At launch:
✅ 3 AI Providers 9+ models
✅ CSV and JSON export
✅ Built-in scoring, no manual tracking

We're just getting started: more models, batch runs, and evaluations are on the way. Feedback shapes the roadmap.
