Genuinely excited to try this out. I've started using Codex much more heavily in the past two months and honestly, it's been shockingly good. Not perfect mind you, but it keeps impressing me with what it's able to "get". It often gets stuff wrong, and at times runs with faulty assumptions, but overall it's no worse than having average L3-L4 engs at your disposal. That being said, the app is stuck at the launch screen…

I have the $20 a month subscription for ChatGPT and the $200/year subscription to Claude (company reimbursed).

I have yet to hit usage limits with Codex. I continuously reach it with Claude. I use them both the same way - hands on the wheel and very interactive, small changes and tell them both to update a file to keep up with what’s done and what to do as I test.

Codex gets caught in a loop more often trying to fix an issue. I tell it to summarize the issue, what it’s tried and then I throw Claude at it.

Claude can usually fix it. Once it is fixed, I tell Claude to note in the same file and then go back to Codex

(I work on Codex) One detail you might appreciate is that we built the app with a ton of code sharing with the CLI (as core agent harness) and the VSCode extension (UI layer), so that as we improve any of those, we polish them all.

Any reason to switch from vscode with codex to this app? To me it looks like this app is more for non-developers but maybe I’m missing something

Good question! VS Code is still a great place for deep, hands-on coding with the Codex IDE extension.

We built the Codex app to make it easier to run and supervise multiple agents across projects, let longer-running tasks execute in parallel, and keep a higher-level view of what’s happening. Would love to hear your feedback!

These paid offerings geared toward software development must be a hell of a lot "smarter" than the regular chatbots. The amount of nonsense and bad or outright wrong code Gemini and ChatGPT throw at me lately is off the charts. I feel like they are getting dumber.

Looks like they forgot the part of the code editor where you can… edit code. Claude Code in Zed is about the most optimal experience I can imagine. I want the agent on the side and a code editor in the middle.

Usage like this is becoming a rarity. Most people are editing significantly less and "agent interfaces" are slowly taking the focus.

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.

To be fair the premise is that they 1 shotted it. I'd just be suspicious if it were any better (the POC is that is just about works)

I agree, if it had been polished I would have not trusted the demo at all, the fact it shows what you can potentially expect from a one-shot is cooler.

Does anybody know when Codex is going to roll out subagent support? That has been an absolute game changer in Claude Code. It lets me run with a single session for so much longer and chip away at much more complex tasks. This was my biggest pain point when I used Codex last week.

It's already out.

Can you explain how to use it? I’ve tried asking it to do “create 3 files using multiple sub agents” and other similar wording. It never works.

Is it in the main Codex build? There doesn’t seem to be an experiment for it.

This looks interesting and I use Codex a fair bit already in vscode etc, but I'm having trouble leaving a 'code editor with AI' to an environment that sort of looks like it puts the code as a hidden secondary artefact. I guess the key thing is the multi agent spinning plates part.

(I work on Codex) I think for us the big unlock was GPT-5.2 and GPT-5.2-Codex, where we found ourselves needing to make many fewer manual edits.

I find that the case too. For more complex things my future ask would be something that perhaps formalized verification/testing into the AI dev cycle? My confidence in not needing to see code is directly proportional in my level of comfort in test coverage (even if quite high level UI/integration mechanisms rather than 1 != 0 unit stuff)

I've had no issues with prompts like that. I use Cursor with their plan mode, so I get a nice markdown file to iterate on or edit myself before it actually does anything.

100% First phase: Plan. Mandatory to complete, as well as get AI feedback from a separate context or model. Iterate until complete. Only then move on to the Second Phase: make edits. Better planning == Better execution

Until a few days ago (when I switched to Codex), I would have agreed. My workflow was "thoroughly written issues" -> plan -> implement. Without the plan step, there is a high likelyhood that Claude Code (both normal or with GLM-4.7) or Cursor drift off in a wrong direction.

With Codex, I increasingly can skip the plan step, and it just toils along until it has finished the issue. It can be more "lazy" at times and ask before going ahead more often, but usually in a reasonable scope (and sometimes at points where I think other services would have gone ahead on a wrong tangent and burnt more tokens of their more limited usage).

I wouldn't be surprised that with the next 1-2 model iterations a plan step won't be worth the effort anymore, given a good enough initial written issue.

I don’t understand why we are getting these software products that want to have vendor lock in when the underlying system isn’t being improved. I prefer Claude code right now because it’s a better product . Gemini just has a weird context window that poisons the rest of the code generated (when online) ChatGPT Codex vs Claude I feel that Claude is a better product and I don’t use enough tokens to for Claude Pro at $100 and just have a regular ChatGPT subscription for productivity tasks .

Cool, looks like I'll stay on Cursor. All alternatives come out buggy, they care a lot about developer experience. BTW OpenAI should think a bit about polishing their main apps instead of trying to come out with new ones while the originals are still buggy.

(I work on Codex) One detail you might appreciate is that we built the app with a ton of code sharing with the CLI (as core agent harness) and the VSCode extension (UI layer), so that as we improve any of those, we polish them all.

Any chance you'll enable remote development on a self-hosted machine with this app?

Ie. I think the codex webapp on a self-hosted machine would be great. This is impotant when you need a beefier machine (with potentially a GPU).
