Why would you use it in VSCode? OpenAI are offering double the normal usage limits for Codex for two months. Go with them and do it in the terminal or the Mac OS codex app if you have a Mac.

It's different to use it in the terminal vs. vscode? Don't have a mac.

Sorry I wasn't aware it's available in vscode. Scratch my suggestion, then.

Yeah they are both fighting for survival. No surprise really. Need to keep the hype going if they are both IPO'ing later this year.

How many IPOs can a company really do?

IPO only ONE but followups are called FPOs.

Can someone explain the difference between this and VSCode agent chat? Except the fact that it's a separate app?

Whats interesting to me is that these gpt-5.3 and opus-4.6 are diverging philosophically and really in the same way that actual engineers and orgs have diverged philosophically With Codex (5.3), the framing is an interactive collaborator: you steer it mid-execution, stay in the loop, course-correct as it works. With Opus 4.6, the emphasis is the opposite: a more autonomous, agentic, thoughtful system that plans deepl…

I'm personally 100% convinced (assuming prices stay reasonable) that the Codex approach is here to stay. Having a human in the loop eliminates all the problems that LLMs have and continously reviewing small'ish chunks of code works really well from my experience. It saves so much time having Codex do all the plumbing so you can focus on the actual "core" part of a feature. LLMs still (and I doubt that changes) can't…

But tokens are way cheaper than human labor

In my personal experience the GPT models have always been significantly better than the Claude models for agentic coding, I’m baffled why people think Claude has the edge on programming.

I think for many/most programmers = 'speed + output' and webdev == "great coding". Not throwing shade anyone's way. I actually do prefer Claude for webdev (even if it does cringe things like generate custom CSS on every page) -- because I hate webdev and Claude designs are always better looking. But the meat of my code is backend and "hard" and for that Codex is always better, not even a competition. In that domain,…

That's the best theory I've heard. Or at least, it's the one that fits with my usage. I'm mostly-backend, and I'm mostly-GPT.

(I'm also a "small steps under guidance" user rather than a "fire and forget" user, so maybe that plays into it too).

I've also had the exact opposite experience with tone. Claude Code wants to build with me, and Codex wants to go off on its own for a while before returning with opinions.

well with the recent delays i can easily find claude code going off on it's own for 20 minutes and have no idea what it's going to come back with. but one time it overflowed it's context on a simple question, and then used up the rest of my session window. in a way a lot of ai assistants have ime have this awkward thing where they complicate something in a non-visible and think about it for a long time burning up con…

The key is a well defined task with strong guardrails. You can add these to your agents file over time or you can probably just find someone's online to copy the basics from. Any time you find it doing something you didn't expect or don't like, add guardrails to prevent that in future. Claude hooks are also useful here, along with the hookify plugin to create them for you based on the current conversation.

Codex now lets you tell the LLM tgings in the middle of its thinking without interrupting it, so you can read the thinking traces and tell it to change course if it's going off track.

That just seems like a UI difference. I've always interrupted claude code added a comment and it's continued without much issue. Otherwise if you just type the message is queued for next. There's no real reason to prefer one over the other except it sounds like codex can't queue messages?

The problem is if you're using subagents, the only way to interject is often to press escape multiple times which kills all the running subagents. All I wanted to do was add a minor steering guideline.

This might be better with the new teams feature.

I wish I could agree with you, but as a game dev, shader author, and occasional asm hacker, I still think AIs have demonstrated being perfectly capable of copying "those effects". It's been trained on them, of course. You're not gonna one-shot RD2, but neither will a human. You can one-shot particles and shader passes though.

I didnt say one shot it, coding agents have been out for more than couple years and yet we cant point to single Good piece of software built by it.

"coding agents have been out for more than couple years"?????

Is it just a game built with LLMs or are you leaning into the cheap content gen capabilities to make the game exceptionally deep/braod?

I'm building all of the systems with LLMs and using LLMs to fast track the creation of content such as storylines, characters, etc. All of the assets are mostly bought and created by me.

Sounds fun! Asset creation...at least in terms of story content, should be the one area where LLMs would really shine, especially if it can somehow extend into logic and gameplay. Couple that with the ways of generating art assets (hard with an LLM, but it can do something at least), that would be cool. I hope to see these games in the future, although they might be labelled as slop unless done really well.
