Asana wipes out 5 years of engineering work in 2 weeks with OpenAI Codex
Asana cleared 5 years of engineering work in 2 weeks with Codex
Asana used OpenAI Codex to remove its outdated testing system, Enzyme, in just two weeks—a task previously estimated to take five years and cost $6 million. The actual cost was about $12,000. Codex agents worked in parallel on separate codebase copies, with engineers reviewing every change. This success has shifted Asana's view on which long-term projects are now feasible, potentially freeing engineers to focus on more creative work.
Not every years-long project will collapse into weeks. But agents can give engineers more room for craft—and make once-impossible work worth attempting.
