OpenAI Codex App Would Have Failed If Released In November

Original post

"The Codex app we released in February, if that had been ready in November, it would've absolutely failed." @ajambrosino

Andrew Ambrosino (@ajambrosino) leads the team behind the Codex desktop app at @OpenAI. Codex usage has 6x'd since February, reaching over 5M weekly active users, and nearly 100% of OpenAI's employees use the Codex app regularly (and not just the engineers).

Andrew's personal mission is to build "the best desktop app that has ever existed, full stop." If you've used the Codex app lately, you know he's not far off from that goal.

In our in-depth conversation, we discuss: 🔸 The "zone defense" model of how PMs at OpenAI operate 🔸 Why AI is so bad at design 🔸 Why Andrew thinks the Codex app would have flopped if they'd shipped it in November instead of February (same product—only the model changed) 🔸 What “taste” really means as a professional skill 🔸 How Andrew uses Codex to run his workflows 🔸 His vision for Codex + ChatGPT

OpenAI Codex lead @ajambrosino: "A lot of companies are getting rid of the product role, saying everybody's just going to be a 'builder.' I think this is a terrible idea."

@lennysan @ajambrosino 这个我挺认。AI 把写和改都压快了，但产品判断不是按钮。越多人能直接 build，越需要有人把目标、取舍、证据和失败边界说清楚。不然就是大家一起很快地跑偏

@lennysan @ajambrosino The role changes, but the judgment does not disappear.

When everyone can build, product work shifts toward choosing the right problem, shaping the use case, and knowing what not to ship.

DMV's already using it to cut wait times. Health Department's streamlining internal workflows. Even cybersecurity's scanning for vulnerabilities. Newsom says it's not about replacing workers it's about making them faster.

And this comes right after the feds restricted Anthropic's most advanced models. California's basically telling DC: "You do you, we'll handle ourselves."

@lennysan @ajambrosino Timing a product launch to when the ecosystem is ready rather than when the product is ready is a discipline most teams never develop because shipping feels urgent every single month. What specifically changed between November and February that made the difference?
