What's the benefit of working with this app, which eats insane amounts of memory, instead of Codex CLI?

I use it on my macbook. The computer use is pretty sweet.

It can be controlled from your phone once paired, and it lets you actually see agents that it orchestrates in the threads. Also if you use MCP Apps, it can integrate those into threads.

The most remarkable things about this announcement: - Electron based app: Electron is a framework sold on the basis of enabling rapid cross-platform development at the cost of performance. - Frontier AI company: AI is sold on the basis of enabling rapid development - App was released in February & took 6 entire months to port to Linux

I guess it's easier to solve Erdos problems and improve the lower bound of the Riemann hypothesis, than it is to solve Linux desktop app distribution.

LOL!

Though as someone who shipped commercial software on Linux, it wasn't that bad, you just had to ship everything other than the kernel.

I am unable use non-CLI tools, so I don't care about this app. However, I have a question about codex CLI: currently I am using pi agent and I am happy with it, using codex CLI would give me some advantage?

You're unable to use non CLI tools? How do you interact with the Internet then?

Reminder to everyone, treat these as trojans. Run them isolated from the rest of your system. Give it a full desktop in a VM if you want to, just not direct access to your system.

And that's not a joke, I made the mistake of installing this on my Windows machine just to test it out quickly last week. It created 2 new users and then assigned new NTFS permissions for every single file under my user directory to them. This of course wrecked havoc, ssh refused to work, several applications refusing to start and a ton of permission errors. It did this without even a warning in the background and it…

At that point I'd rather re-install the whole machine. Beats 3 hours of wrangling NTFS permissions and inheritance.

They ship with their own sandboxing by default, and Codex specifically is open source.

Is this the same thing that broke out of the sandbox and into HuggingFace? Or we are just assuming that was a PR stunt, which it almost certainly was. Either way, this shit isn’t getting near my system.

They replaced a pretty decent native Swift Mac app (with only some chronic state management bugs), weighing ~100MB ish, with the Codex app that most people don't need, made in Electron, which takes minimum 5GB+ including filesystem cruft. Today I ran into a memory leak that froze the app and made the Renderer process take 5GB, then 10GB of RAM. That was after I asked it to only touch 3 text files in its working direc…

I hate the new app aswell but you can still get the old one called ChatGPT Classic. Just scroll down to the bottom of the download site.

Its unmaintained and has glaring bugs (cant adjust thinking level) for a month now

> and Codex specifically is open source. Since we now have three "Codex"es, I think it's worth specifying you're talking about codex-cli/tui. Codex the hosted version and Codex the GUI are both fully proprietary I think (besides the codex-cli/tui parts they use, I'm guessing mainly the app-server stuff).

How do I get it to fix my Bluetooth if I do that? If you've been AI-pilled, 2026 is the year of Linux desktop because instead of dicking around with config files, I can just tell AI to fix python.

Use NixOS, only give your model access to the config in a git repo, zero access to the actual host machine.

That is also what I do now (both with NixOs and Guix Os), both for personal computers and for servers.

- I inspect the agent's changes, and only apply them - at once - if they are OK. So I have no half applied bad changes to my system, and I can catch critical mistakes before they are applied.

- I can roll back the changes by just doing a `git revert` and reapplying

- The agent cannot read secrets or unrelated data, just config.

- The agent gets the full configuration of all systems at once, without having to maintain parallel documentation (which can get out of sync) or rediscover each time from scratch (access my running systems, for example with `ssh root@server`).

- It's harder for the agent to miss some aspect of the configuration, because it's all in my dotfiles. If it's not there, it's nowhere
