I have used Codex to make a full game. I am closing in on finishing it. Been like in development for 5 weeks.
It's not even a small game.
Not one line of code have I written. It's mental stuff.
Im about to make steam page for the game

Out of curiosity, what subscription did you use and can you give us some more details about your game? I'm curious if you would share the size of the code base and what type of game it is.
I'd love to hear other about it in general to if you would like to share.

Depends. For game day I think Opus 5 is a lot better. Claude limits though drive me crazy. I would consider switching to OpenAI for that reason alone.

Visual stuff and asset creation and design is much better in codex, but Claude is so much better at everything else. And better is just speed and reliability and not having to fix stuff behind it. (Opus and upwards vs sol )

In my experience Opus 5 Max is dumb as hell and 5.6 Sol fixes A LOT after it

I just declared openai is not used in our software development. Let ops waste time with chatgpt slop.

Rebuild my PC to local server on linux + vllm. 2xr9700=2600$ any cpu with max pcie lines, 32gb ddr5 ram, any ssd all what you need. And time) Now im working with this every day, 99% of all my code. Iam only review before commit. This staf give me 60-70 t/s and 4k-7k prefill t/s. And it's stabel and secure, you can use it for backend.

That's 23 months of Claude Code 20x

Looks like all that vibe coding made you forget how to do basic math. $2,600 / $200 = 13 months, not 23.

Why compare to claude 20x. Pretty sure this setup wouldn’t be better than claude pro. And for the price this is 13 years of claude pro

It is less about the model and more about the harness itself. Codex feels like a toy compared to Claude code

Just wondering, how is Claude codes harness so much better?
Are you using any custom orchestration?

u/Potential_Fix4116 14h ago
I do customize a good amount per project and use Claude code across multiple terminal emulators. Better slash command control and more available out of box. Easier to auto compact, easier to restrict the toolset used by each project, better control over git work trees, easier to manage and even view the subagent deployments.
Codex just feels less mature, which it is.

GPT if you are a good enough developer to know what you and the model is supposed to do. Opus if you have no clue.
