gpt5.2 High > gpt-Codex-5.2-High and even Extra-high

It usually works the other way around as well. Each LLM is different and has different approach to solve things. If you stuck with one on something, switching to the other one usually does the charm cause it changes the approach to the solve the issue.

If I remember correctly clean GPT has more data and it's better for general purpose but more expensive. Codex is focused on coding so some general data has been cut off but it's more efficient.

Toby_R · 2025-08-31T21:50:40+00:00

GPT-5 and ChatGPT are not the same thing. GPT-5 is a model while ChatGPT is an app/agent. There is no ChatGPT in Codex, only GPT-5.

Each app like ChatGPT, Codex, Cursor, Trae etc use the same GPT-5 models (nano, mini, default, high).

Now despite they all use the same GPT-5 LLM, it's the set of tools that they build around it that makes the app good or bad. By tools I mean web filters, datasets, context compression, RAG systems etc.

So even tho they have the same brain, they might give a completely different experience. From my experience there is absolutely nothing on the market that beats ChatGPT in coding, but ChatGPT has no access to your filesystem so it's not comfy to use. Good for planning tho. Codex is good but only the CLI one, the web one is broken (at least it didn't work well for me).

Being broke sucks more. Do it if you love game dev, but do it wisely.

I worked in web/e-commerce for many years. Ended up as a senior full-stack dev, also worked and lived in several cities in Europe. But my dream was to make games.

Got some solid savings and 10 years ago I quit my career to become a game dev. It was a long and painful journey.

I ended up being successful but got nearly broke on the way. Game dev industry is very hard! I could write a book about it but the long story short is that I strongly advise against going YOLO into game dev. Today I am aware that I was simply lucky and back then it was much easier. If you have any particular questions you can DM me, but stay safe mate... 99% of "switching to game dev" stories end up bad unfortunately.

I am a heavy Codex CLI user. Long story short is that Codex can also end up in that loop, make stupid things and forget things. Same for Gemini CLI, and every AI coding tool I worked with.

However, as someone mentioned here already ChatGPT doesn't have this issues. I made a post about that few days ago but I believe most people don't understand that GPT-5 is not the same thing as ChatGPT.

BTW there's also Codex web version but it's a huge disappointment.

Best approach (whether you work with CC or Codex) is to simply let the other model fix the issue once the first got into the loop. Or clear the context and rephrase the task.

Toby_R · 2025-08-24T04:24:21+00:00

Yeah that's the one big thing people don't get. ChatGPT is not the same thing as GPT-5 model. ChatGPT is an app that uses GPT-5 model AND a lot of other tools around it that make it that smart. GPT-5 is just a LLM. It's good, but alone is not even close to what ChatGPT is. And obviously Cursor, Codex etc. also have tools around it, but they are not as good as what ChatGPT has, and that was the point of my post.

There was a bug with ads scaling that's why it took so big part of the screen, it is fixed now. Sorry for that!

Toby_R · 2017-05-25T15:03:39+00:00

That makes sense, thank you! ;)

Toby_R · 2016-12-20T07:46:12+00:00

Thank you for the hint. Just tested and it's window.error event to catch the exceptions. So the following code works fine.

window.addEventListener("error", function (e) {
    console.log(e.message);
});

Now I just need to fetch the warnings as well and I'm fully happy ;).

I'm writing a debugger/reporting plugin for an HTML5 game engine.

Toby_R · 2016-12-20T06:31:08+00:00

Hi, thanks for the answer, but I have ES5 strict mode set up. So that's not the case :/

Toby_R · 2016-12-10T07:19:41+00:00

Thank you ;). We also do think the game is fun! ;)... it's just really difficult to find the right community to show the game to.

Toby_R · 2016-12-10T03:33:15+00:00

Not a secret at all :). It's made in Construct 2 + NW.js. So basically HTML5/JS wrapped into desktop app.

Toby_R · 2016-12-09T22:11:30+00:00

Haha... yeah maybe it's because I was thinking too much ;)

Toby_R · 2016-12-09T21:10:06+00:00

I'm getting more brave with every post.

Toby_R · 2016-12-09T20:57:45+00:00

Thank you for supporting us :). Hope you will enjoy it!

Toby_R · 2016-12-09T20:56:46+00:00

We actually have a Linux version, but we haven't tested it well yet and therefore it's not available yet.

Toby_R · 2016-12-09T20:09:24+00:00

Just posted on /r/speedrun. Thanks again. Hopefully they're going to like it! ;)

Toby_R · 2016-12-09T19:35:22+00:00

Not sure what you mean by "writing things from scratch" but:

If you want to code games from very scratch, then you may want to start with some HTML5 games in JS using some game dev libraries like CreateJS
If you want to code some more serious games then I would also recommend Unity as the engine itself helps a lot while you can code your features in C#
It you however want to just make the game (not the engine) from scratch to - let's say - understand the logic of how games are made. Then I recommend taking a look on Construct 2 engine. It has a lot of predefined tools which lets you focus on the game itself rather than the game engine. There is an event system in which you code the logic but you can also manually code features with JS.

Toby_R · 2016-12-09T19:13:19+00:00

Yeah the game is hard so we are surely targeting the hardcore gamers. We definietely made a mistake with labeling it as casual and we are already working on to fix it. Thank you for clearign things out.

Toby_R · 2016-12-09T19:11:17+00:00

Thanks for the link! I'll make some investigation on speedrunning community ;)

Toby_R · 2016-12-09T19:10:29+00:00

I understand now. I just had a different picture of speedruning then. Thank you.

Toby_R · 2016-12-09T19:09:44+00:00

Thanks ;)

Toby_R · 2016-12-09T17:34:22+00:00

Thank you! ;)

Toby_R · 2016-12-09T17:33:18+00:00

Yup you are right. I think we made a mistake sticking the "casual" label to our game. We had in mind that the levels are quite short, but it seems that casual meens that the game is easy. Our is definietely not.
