Setting Up Automations and Computer Use

Andrew Ambrosino leads development of the Codex desktop app at OpenAI. Nearly 100% of OpenAI employees—not just engineers—now use Codex weekly. A lifelong builder with a background spanning engineering, design, product management, and founding companies, he is now responsible for turning the Codex desktop experience into what he calls “the best desktop app that has ever existed, full stop.”

In our in-depth conversation, we discuss:

1. Why AI has completely flipped the product development process

2. What “taste” really means as a professional skill, and why it is emerging as the most valuable capability in an AI-first workplace

3. Why Andrew believes the Codex app would have failed if they launched it last November (vs. in February)

4. The “zone defense” model for how product managers at OpenAI operate when everyone can build anything

5. How roles are collapsed on Andrew’s team, and why eliminating the concept of roles entirely is a big mistake

6. How Andrew uses Codex to run his own workflows

7. The vision for a home base that coordinates work across ChatGPT, Codex, and the tools people already use.
