But what if the code is on my laptop? Alongside the tools needed to work with it Case in point, I have a Rust project with a target/ directory with about 10GB. Compile times from scratch takes about 10 minutes. (I do not love this) With this mobile app I need to upload the code to the cloud, right? Or does OpenAI expects me to compile huge projects on my phone?

No, the phone connects to your local device. This isn't "codex web" on mobile. Basically you work through your desktop on your phone. So to be clear, there are security risks (you can wipe your entire desktop from your phone).

Not if you use Linux; app not available yet.

(Someone deleted a comment about why you'd want a mobile Codex app. This is the answer I wrote.) Once you've used these coding agents a lot, you develop a pretty intuitive feel for how they work, what they're capable of, what they're good at, and where their weaknesses are. Hopefully, you're already pretty familiar with the code base you're working on. Combining the two, this means you can get quite far essentially "…

You must be kidding me.

The best part is you don't have to stay at home waiting codex thinking, you can go out grab a coffee while connect your Codex and ask it to work

Surely you mean grab a coffee and sit back down at your desk in your corporate office, because working remotely while your agent also does so is just preposterous.

How much better is it than Claude? I have both but Claude sucks up so many tokens.

5.5 is absolutely comparable to opus 4.7 (both on highest effort), maybe even better. It generally seems less lazy, faster, and writes code closer to what I'd write. The only downside is that for very very long tasks, it can kind of lose track of the goal. For tasks under ten minutes I'll go with codex every time.

They've added a new goal mode that might help with that

What OP said works quite well for a lot of tasks, and if you've set up base instructions on coding style they (Codex, Claude) generate code accordingly.

A key point is that after the "vibe" session you should also have a lot of tests written. So they can easily refactoring the code afterwards if there are major aspects you don't like when you get back to your desktop.
