The Codex App

I'm managing context with codex inside VSCode using different threads. I'm trying to figure out if there are use cases where I'd rather be in this app.

How is this better than vscode with the codex extension?

Having dictation and worktree support built in is nice. Currently there is a whole ecosystem of tools implementing similar functionality for Claude Code. The automations look cool too!

Is this not just a skinned version of Goose: https://block.github.io/goose/

Bugs me they treat MacOS as first class. Do people actually develop on a Mac in 2026? Why not just start with Linux?

seems like I need to update my toolset for the 3rd time this week

Currently using opencode with Codex 5.2 and wondering why I should switch.

What are the max context sizes ?

Does this support users who access Codex via Azure OpenAI API keys?

Built an open source lightweight version of this that works with any cli agent: https://github.com/built-by-as/FleetCode

Kind of embarrassing to demo "Please change this string to gpt-5.2". Presumably the diff UI doesn't let you edit the text manually? Or are they demonstrating being so AI-brained you refuse to type anything yourself?

This is so garbage. OpenAI is never catching up.

The inclusion of a live vibe-coded game on the webpage is fun, except the game barely works and it's odd they didn't attempt any polish/QA for what is ostensibly a PR announcement. It just adds more fuel to the fire to the argument that vibecoding results in AI slop.

Maybe I'm just not getting it, but I just don't give a flying fuck about any of this crap.

Like, seriously, this is the grand new vision of using a computer, this is the interface to these LLMs we're settling on? This is the best we could come up with? Having an army of chatbots chatting to each other running basic build commands in a terminal while we what? Supervise them? Yell at them? When am I getting manager pay bumps then?

Sorry. I'll stick with occasionally chatting with one of these things in a sandboxed web browser on a single difficult problem I'm having. I just don't see literally any value in using them this way. More power to the rest of you.

I love competition

It keeps offering me to "Get Plus" even though I am signed and already have a Plus plan.

Codex really grown on me lately. I re-signed to try it out on a project I have and it turned out to be really great addition to my toolkit.

It isn't always perfect and it's cli (how I mostly use it) isn't as sophisticated as OpenCode which is my default.

I am happy with this app, I am using Superset, terminal app which suprisingly is well positioned to help you if you work in cli like I do. But like I said, new desktop app seems like a solid addition.

> Work with multiple agents in parallel

But you can already do that, in the terminal. Open your favourite terminal, use splits or tmux and spin up as many claude code or codex instances as you want. In parallel. I do it constantly. For all kinds of tasks, not only coding.

Does the Codex app host MCP Apps?

I really want to like the native Mac app aesthetic but I kinda hate it. It screams minimalist but also clearly tells me it’s not meant for a power user. That ruggedness and sensitivity is missing.

No Linux support? :(

> We're also excited to show more people what's now possible with Codex . For a limited time we're including Codex with ChatGPT Free and Go, and we're doubling the rate limits on Plus, Pro, Business, Enterprise, and Edu plans.

Translated from Marketingspeak, this is presumably "we're also desperate for some people to actually use it because everyone shrugged and went back to Claude Code when we released it".

[dead]

Given the prevalence of Opencode and its ability to use any model and provider I don't see reason why would anyone bother with random vendors half-assed tools.
