Software engineers become AI experts

Optimize AIs and Search Engines to magical levels of performance by leveraging a sophisticated toolkit packed behind simple APIs.

Without Pi Labs

Stuck at “cool demo” stage, with no tractable path forward.

Disjoint AI & Search stacks making building grounded responses really hard.

Lost in the noise of the constant stream of AI research.

Scarce & expensive ML and data science expertise out of reach.

With

AI scoring & optimization toolkit from metrics, to training, inference & feedback loop algorithms.

High quality search algorithms shaped and optimized to your AI, data and queries.

Latest research & papers in AI packed behind simple to use APIs.

Empowered software engineering teams doing core AI work.

Pi's Architecture

You bring your domain knowledge. Pi does the algorithmic heavy lifting.

Pi's architecture decouples domain knowledge from ML and data science algorithms, simplifying your interface to your AI and Search systems without sacrificing any of their power.

Scoring System

Measuring the performance of your AI system is a difficult data science problem. Finding the ten metrics, that when they go up, mean your application is getting better requires a lot of work in creating and calibrating measures in your application. Use Pi's Scoring system to gain visibility on the performance of your AI across both training and inference.

Prompt Migration

Updating your prompt to add a new feature or to calibrate to a model migration takes hours if not days of work. Set up your scoring system and run Pi's prompt optimizers to get the best prompt for your application.

RAG Ranking Optimization

Getting high quality search results requires building more optimal rankers. Combine Relevance with custom domain measures to optimize your RAG stack for your agents and AI systems.
