Build your own AI infrastructure stack with TypeScript - handles multiple LLM providers, agent workflows, and human-AI collaboration patterns in one cohesive framework

Every developer building with AI hits the same wall: juggling multiple LLM APIs, managing complex agent workflows, and figuring out how humans and AI should actually work together. This isn’t another chatbot wrapper - it’s a complete infrastructure blueprint for serious AI applications.

Built in TypeScript with Bun, PAI gives you the plumbing for multi-agent systems, provider abstraction across OpenAI/Anthropic/local models, and thoughtful patterns for human-AI collaboration. The 8,877 stars come from developers who’ve realized this solves the messy integration work they were about to build themselves. Version 3.0 just dropped with enhanced agentic workflows and better TypeScript definitions.

Perfect for engineers building AI-first applications who want infrastructure that scales beyond simple API calls. The documentation assumes you know what you’re doing, and the codebase is clean enough to fork and customize. If you’re tired of reinventing AI infrastructure wheels, this is your starting point.
