OpenAI Codex agents complete 5-year Asana migration in 1.5 weeks
kimmonismus · x · 2026-08-20
A migration task at Asana, originally scoped at five years and roughly $6 million in staffing, was completed in about a week and a half using OpenAI's Codex agents.
Key Details:
- Objective: Remove the obsolete React testing framework Enzyme, which was blocking frontend upgrades.
- Workflow: Up to four Codex agents worked in parallel on separate codebase copies, with engineers reviewing proposals twice daily.
- Cost: The total cost for model and infrastructure was approximately $12,000, drastically lower than the estimated human labor cost.
- Impact: AI coding agents reduced the timeline from five years to 1.5 weeks.
