   Meta explains how it built Forum with an AI agent that verifies its own work

   AIMeta's engineering team describes building Forum, a standalone Facebook Groups app, with an AI agent that plans, builds, tests, and corrects its own work. The team says it reached core feature parity with Facebook Groups in eight weeks and, through a stress-testing loop, roughly halved memory use and page faults. The source says engineers still approve each release, and it does not disclose team size, full feature scope, or whether the system is open source.
