What's really happening inside OpenAI's Codex team and how they actually use their own tools?

The common story is that coding agents help engineers write code faster — but the reality is far more expansive.

In this video, I share the inside scoop on how OpenAI builds with Codex:
• Why every PR at OpenAI gets reviewed by Codex automatically
• How designers and non-technical staff ship production code daily
• What junior engineers do differently that makes them outperform veterans
• Where coding agents are headed when generation becomes solved
