What it does
Pocket Flow is a very small framework, about 100 lines of code, for building apps that use AI language models.
It models everything as a simple graph of steps, which its makers say is enough to build common patterns like agents, workflows and question-answering over documents.
Because it is so small and has no extra dependencies, you can copy the code directly into your own project.
Who it's for
Developers who want a minimal, no-frills base for building AI agents and workflows.
