The Pulse: We need to talk about migrations with AI

AchievementProductAug 27, 2026

OpenAI claims Asana used OpenAI Codex to remove its outdated Enzyme testing system in two weeks for roughly $12,000, versus an estimated $6M staffing plan. Gergely finds the two-week timeline credible, citing Airbnb's LLM-aided migration of 3,500 Enzyme tests in six weeks, but considers the five-year, $6M cost estimate inflated. He notes cheaper models could reduce the $12,000 cost further.
