Why Pi's scoring models?
Metrics you can trust, ready for offline evaluation and online inference
Smart about your app.
Not sure what to measure? Pi figures it out for you. Feed it any or all of your prompts, your PRDs, your user feedback, or just sit down and chat with it and it will help you figure out the best calibrated metrics for your application.
Highly accurate. Insanely fast.
Tap to view
Our foundation model, Pi Scorer, scores more accurately than Deepseek and GPT 4.1, but runs at the size and speed of GPT Mini and Gemini Flash. You can score 20+ custom dimensions in less than 100msec; it’s that fast.
One scorer; All integrations.
Tap to view
A single Pi Scorer can be used in every part of your AI stack and existing tools: offline evals, online observability, training data quality, model optimization, agent control flows and more. Easily plug Pi into Google Spreadsheets, Promptfoo, CrewAI, or any other tool you might be using.
