Asana revealed that OpenAI Codex completed a massive engineering migration in two weeks—a task originally estimated to take at least five years and cost roughly $6 million.
- Project: Removing Enzyme, an outdated testing system blocking frontend stack upgrades.
- Method: Used a five-sentence prompt with up to four coding agents working in parallel. Human engineers checked progress roughly twice a day and reviewed every change.
- Insight: Simpler instructions outperformed elaborate setups.
- Results: Expected ≥5 years vs. 1.5 weeks of effort; estimated $6M vs. $12k in model and infrastructure costs.
