Asana used OpenAI Codex to replace an outdated testing system in two weeks for about $12,000 in model spend.
OpenAI published a customer story on Asana using Codex to replace an outdated testing system. The work was expected to take five years of engineering effort and was completed in two calendar weeks.
Model and API costs for the project came to roughly $12,000. The case is presented as an example of Codex applied to large-scale legacy migration rather than greenfield development.
It is aimed at engineering leaders weighing the economics of agentic coding tools.
