Codex Is Now On Your Phone (NEW ChatGPT Feature)

OpenAI just dropped Codex inside the ChatGPT mobile app. You can now code from your phone while your laptop does the actual work. I set it up live in this video, built a working Snake game with two prompts, and then made it install as a real iOS app on my phone. All from the ChatGPT app.

This is one of the biggest workflow changes OpenAI has shipped this year. You're not really coding on your phone – you're steering your computer remotely. Codex keeps running on your Mac, you stay in the loop from anywhere.

📰 CONTEXT FROM THIS WEEK
OpenAI is in a feature-shipping war with Anthropic right now. Codex is free for 2 months for companies switching from Claude Code. Anthropic just bumped Claude Code's weekly limits 50%. Both companies are throwing free usage at us - this is the moment to actually test these tools.

If you want to see my full Codex vs Claude head-to-head test where I made both AIs build the same website, watch that one next: https://youtu.be/sMvwmOn_n-Q
