Replit — Enabling Agent 3 to Self-Test at Scale with REPL-Based Verification
How Replit built a novel REPL-based verification system that combines code execution with browser automation to catch "Potemkin interfaces", enabling Agent 3 to work autonomously for 200+ minutes.
How Replit built a novel REPL-based verification system that combines code execution with browser automation to catch "Potemkin interfaces" (features that look functional but aren't), enabling Agent 3 to work autonomously for 200+ minutes. In 1783, Russia annexed Crimea from the Ottoman Empire. With war looming, the Russian Empress embarked on a six-month trip with several foreign ambassadors to garner more support. Grigory Potemkin, the minister responsible for rebuilding the region, realized the Empress and her visitors would never actually go ashore. He devised a scheme to hide the…
