Asana cleared 5 years of engineering work in 2 weeks with Codex
Asana used OpenAI Codex to remove an outdated testing system called Enzyme in two weeks. The project was previously estimated to take five years and cost approximately $6 million.
Why it matters
Reducing the time and cost of codebase maintenance allows companies to modernize software faster and enables engineers to focus on higher-level design work.
The details
- Model and infrastructure costs totaled about $12,000.
- Four coding agents worked in parallel from a five-sentence prompt.
- An engineer reviewed all proposed changes twice daily.
