OpenAI Codex let Asana rewrite its entire test harness in two weeks for ~$12K instead of five engineer-years. This means any team maintaining legacy test suites can now slash refactor costs by 100x and ship modern, maintainable code without multi-year roadmaps—if they’re ready to accept Codex’s current limits on context and determinism.
Replacing an outdated testing system estimated to take five years of manual labor was completed in just two weeks for $12,000 using Codex. This shifts large-scale legacy codebase migrations from multi-year, budget-killing roadmaps into cheap, automated tasks you can deploy immediately. Engineers running production systems can now aggressively target and refactor ancient, mission-critical technical debt that was previously deemed too expensive or risky to touch.
