(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 "…

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?

Not sure about how it works with Codex now, but with Claude you can just start a terminal session of claude code with your code checked out locally on your computer, and then enable remote control which lets you control that session from your phone.

So basically, it is like you are typing on your terminal on your computer from your phone.

A while ago I created a telegram bridge for AWS Kiro CLI, this allows my to talk to the agent running on my server from anywhere. Any remote access to any of these agents is a massive game changer, it means that you don't need to hover infront of the pc while it works away at the problems. It changes your workflow, but I do find you need to force yourself to "turn off", its easy to do that with the PC, eg, just walk away, but when you can just "get the agent to do one more change" while waiting to pick the kids up or taking the dog for a walk, it can get difficult to stop.

I wish they'd have done this in a separate Codex app. On desktop I greatly prefer having Codex separate from ChatGPT... As compared to Claude, which is growing so fast and adding features so quickly it seems bolted together (I get why they do it, integrations/MCP-wise).

This specific feature is more akin to Remote Control in Claude. You could already kick off Codex Cloud tasks (although it's just a little more fiddly to do so).

If you can move to Codex Cloud (or "Claude Code for the Web"), I think it's the superior approach. Start it there, and just pick it up from the PR if necessary.

On which plan? I can go through a 5-hour limit with a $20/mo Plus subscription in a few minutes with 5.5 Extra High. This causes me to reserve the latest/best rev for the harder problems. 5.5 really does seem to be very superior to 5.4, but it's also very expensive to run: The gas gauge moves fast . It's not very clearly defined whether 5.5 will cost less to get a problem solved quickly, or if a bunch of automatic it…

The standard $20 plan, on my existing Godot code: https://github.com/InvadingOctopus/comedot Most of those commits since the last few months are thanks to Codex reviews (but the code is not AI generated): 5.5 since it came out, and 5.4 etc before that, almost always on Extra High because it's for a framework that underlies the other stuff I do so I want make to sure everything's correct. Sometimes I have to run multi…

Thanks. That's good data.

I'm taking this, along with my own experience, to mean that the GPTs are cheaper to use for refactors of an existing body of work than they are for creating a new one.

(And perhaps part of that is in the name? These "LLM" contraptions are very good at translation, after all. And tokens seem to relate more to concepts than to specific phrases or words.)

It's not that I'm unimpressed by the results, it's that I think I'm saving time by pushing the agent along remotely, but the reality is that my messages to the agent(s) end up being a lot shorter, which inevitably leaves more up for interpretation. Don't get me wrong, I still use Codex (and sometimes Claude Code) remotely every day, and am overall excited for this release, it's just that the benefit wasn't as high as…

Just...write longer messages. Maybe it is age but I've written huge forum such as on HN all from my phone often with multiple tabs open to source various links for foot notes. When I type for an LLM, I will type a lot too if needed and will often even type a little, wait to think, then continue, over the course of like 15 minutes even, so that the intention of the prompt is correct since that saves much more time and…

Oh, I agree completely. I avoid loose language, revise my wording, and usually write prompts that require scrolling on mobile.

It isn’t so much that I feel restricted, I guess it’s that mobile wasn’t as big of a game changer as it was ~6 months ago.

My bandwidth feels more restricted by my own cognitive capacity (usually due to do context switching), rather than the limits of the model itself, and the mobile interface makes that worse.

I’ve recently found myself reserving larger tasks for “keyboard time” and reverting my thinking back to notes (in mobile), which I’ll then formulate to the LLM at some future time.

> What tunnel setup do you use by the way?

I “vibecoded” an agentic runtime that operates my machine generally (including TUIs like Codex/Claude Code), which I connect through a custom proxy and mobile app (both also vibecoded).

I previously tried Cloudflare Tunnels and an SSH setup, but it all felt a bit hacky.

Unfortunately the app is iOS only, but I could open source it and you’d probably be able to make an Android clone quickly (:

I've been coding on Android for a few months, mostly while walking around outside or showering. I'm on a mix of Tailscale + Termux + ssh server + tmux + codex CLI, Tailscale is great.

I think you may be able to optimize your workflow more by drafting your prompt in ChatGPT first; get it to expand out the intent for you. Doing that has made phone coding a lot more tolerable for me.

I like to think that I've given phone coding a fair shot (and I continue to do it), but I agree with the other poster that there's something about the lack of a keyboard that really gets to me :) I wish I knew what it was.

I tried Codex web. It kinda sucks and OpenAI doesn't seem to be promoting it? Look elsewhere if you want a Linux VM in the cloud. (I quite like exe.dev and they do have good mobile support.)

It's beyond terrible. Like they're routing to gpt4o mini with low effort behind the scenes. Just let us pick the model and the effort.

This is the EXACT evolution of this product that I've wanted. For simple tasks on some of my desktop machines, I don't want to mess with SSH or remoting into them, I just want to tell an AI agent what I need, let it build a plan that I press "Approve" on, and let it rip. This is the ClawdBot killer!
