Pi Labs
What is Pi Labs?
Pi Labs offers an AI-powered platform designed to automatically build evaluation systems (evals) for AI applications, particularly those involving Large Language Models (LLMs) and agents. It enables users to create custom scoring models that precisely match user feedback and prompts, ensuring highly accurate and consistent evaluation. The platform integrates seamlessly with various existing tools and provides a fast, highly accurate foundation model called Pi Scorer for comprehensive metrics, observability, and agent control across the entire AI stack.
How to use Pi Labs?
To use Pi Labs, you first work with Pi's copilot to build your custom scoring system. This involves feeding it your prompts, PRDs, or user feedback, or simply chatting with it to define the best calibrated metrics for your application. Once the scoring system is established, you can then use it to evaluate anything across your AI stack, including offline evaluations, online inference, training data quality, model optimization, and agent control flows.
