Amjad Masad: Replit 'Closed the Loop' — the Coding Agent Is Now Self-Improving

X/Twitter (Amjad Masad)via @amasad·medium signal

Replit CEO Amjad Masad posted on July 6 that the reason Replit's agent is improving so rapidly is that 'we closed the loop and the agent is self-improving,' promising technical details. It's a direct founder claim that a production coding agent now upgrades itself run-over-run rather than waiting on model releases — the same self-improving-outer-loop pattern builders running their own harnesses care about. Single primary source (Masad's own post) pending the promised writeup, so treat the mechanism as asserted, not yet documented.
