funkai
Funk-tional AI SDK framework

A composable AI microframework built on ai-sdk, curried with funk-tional programming flair.

Quick StartIntroduction

Functions All the Way Down
agent(), tool(), flowAgent() are plain functions returning composable objects. No classes, no decorators, no inheritance — just functions you can read top to bottom.
One API, Zero Workflows
agent() for single-turn, flowAgent() for multi-step — same programming model, same hooks, same tools. No workflow DSL to learn, no orchestrator to configure. Just functions that compose.
Type-Safe Prompts
Write .prompt files with YAML frontmatter and LiquidJS templates. Build-time codegen produces fully typed TypeScript modules with Zod validation.

Packages

Reusable modules shared across the codebase — libraries, utilities, configs, SDKs, and internal tooling.
