How Meta Built Forum With AI-Native Engineering

How Meta Built Forum With AI-Native Engineering

From the official release

  • Meta’s newest app, Forum, is for anyone who wants to go deeper into the conversations in their Facebook groups.
  • To build Forum, Meta engineers adopted a whole new way of working by bringing an AI agent into the development cycle.
  • We’re sharing insights into what it took to build Forum with agentic AI: how we adapted the codebase, tested frameworks and internal tooling for agentic execution, what worked, and what didn’t.

Forum is a standalone Groups app that a small team built from scratch. It’s also where we tested a different way of working: treating an AI agent as a participant in the engineering process rather than a faster way to type.

That experiment needed a definition of success, and ours wasn’t code volume. We measured verified, production-ready outcomes — changes that build, pass tests, and survive review.

From Human-In-The-Loop to Human-On-The-Loop
