Stop Building GPT Wrappers, Build a World Model Instead

Foundry is building core infrastructure for browser agents, not GPT wrappers. They argue that every SaaS app and enterprise tool without an API will soon be automated by browser agents, but current browser agent technology is in its infancy. Foundry aims to build hyper-realistic, deterministic web simulations, a comprehensive annotation framework, reliable benchmarks, and robust RL training environments to improve browser agent reliability and efficiency. They are seeking a senior software engineer to build core ML systems and RL infrastructure from scratch.
