Pi Agent Framework

A high-performance TypeScript framework for building autonomous, multi-agent systems with native tool-calling and state persistence.

Pi Agent Framework provides the scaffolding for resilient AI agents via a modular architecture (Engines, Tools, and Memory). It supports LLM providers like OpenAI and Anthropic out of the box, focusing on low-latency execution and reliable task delegation. Developers use it to orchestrate complex workflows where agents must maintain context across sessions, execute local code, and interact with external APIs through structured schemas.
