# Asana Uses OpenAI Codex to Complete 5 Years of Engineering in 2 Weeks for ~$12K

## AI commentary

> The real value of this case is not just that 'AI is powerful'—it provides a concrete cost-benefit comparison: $12,000 versus five years of engineering. For CTOs and engineering leaders, it offers a real sample for rethinking technical debt and R&D budgets. However, Codex's success here depends on Asana's existing engineering setup and acceptance processes, so replicating these results requires the team to have the right capabilities.

## At a glance

OpenAI published a case study showing Asana used OpenAI Codex to complete an engineering overhaul estimated at five years of work in just two weeks, replacing an outdated testing system for about $12,000. The project involved migration, refactoring, and validation across a large codebase. Asana engineers said the agentic coding workflow delivered dramatic speedups, while emphasizing that clear acceptance tests and human review were essential. The case highlights how AI coding agents can reduce technical debt at a fraction of traditional cost, and raises questions about future software engineering team structures and budgeting. It is a concrete, official example of AI moving from prototype assistance to production-grade infrastructure work.

## Key points

- Asana replaced an outdated testing system with Codex, completing roughly five years of work in two weeks.
- Total cost was about $12,000, far below traditional engineering labor costs.
- The case shows AI agents are practical for large-scale legacy codebase refactoring.
