HA7CH School

An open-source school for learning to work with AI — and a practical entry into forward deployed engineering. An agent tutor adapts to each learner, guiding them from core ideas to hands-on work: understanding a business, finding the real problem and building something useful.

HA7CH is China's first and largest open-source community for forward deployed engineering, building an AI-native movement in China. More than 5,000 people follow it, and over 1,000 have joined its in-person events. Through an open school, AI-native event software and a playable FDE training ground, HA7CH helps people learn, meet and put AI to work in the real world.
