Asana reported using OpenAI Codex to replace an outdated testing system, according to OpenAI. The company completed the work in two weeks—an effort it had estimated would take about five years—at a cost of roughly $12K.
Why it matters
The account frames AI coding tools as a way to accelerate long-standing engineering tasks that would otherwise require extended timelines and higher costs. The stated compression from years to weeks illustrates the potential scale of impact when applied to modernization work.
Who should care
Engineering teams and organizations maintaining legacy systems may be interested in how AI coding assistants are being applied to modernization and testing efforts.
