Demand Grows for 'Flight Simulators' to Stress-Test AI-Written Software

As companies build more applications with AI, demand is rising for software that stress-tests them by simulating network failures, cyberattacks and rogue-AI attacks. Replit uses a deterministic simulator that reruns the same failure scenario to test different fixes. Using today's AI models to evaluate code often produces false alarms.

• Replit uses a deterministic simulator for failure testing
• Simulator reruns one scenario to test different fixes
• AI-based code evaluation often produces false warnings
• Demand rises alongside growth in AI-written software
