Codex CLI IDE just works, very impressed with the quality. If you tried it a while back and didn’t like it, try it again via the vscode extension generous usage included with plus. Ditched my Claude code max sub for the ChatGPT pro $200 plan. So much faster, and not hit any limits yet.

i just use aider + gemini pro, here's the project i developed: https://aretecodex.pages.dev/tools/

Did anybody switch away from Aider for a compelling alternative? What was the feature?

? Isn't lmstudio API openai compatible? Codex cli already supports 3rd party models, you have to edit the config yaml file, and you can add many model providers.

I never managed to get it to work. I used chatgpt to try to do it for me :)

This is how I did it - https://github.com/openai/codex/blob/main/docs/config.md#mod...

I have it go to openrouter, and then you just export the API key and run codex, works smoothly.

I still like aider but multi-step agentic flows are very useful so I mostly use codex and claude nowadays. If I want to do very specific edits I use aider.

I don't find multiple agents helpful at all for coding, here you can see i am running a modded aider and single shot most features, https://www.reddit.com/r/ChatGPTCoding/comments/1nh7bu1/3_ph...

I also use claude or codex but i do not find them much useful for what i do.

It is 100% true. And they are rapidly losing users to Codex. Charts were shared recently showing a massive migration underway.

Oh yeah, Sonnet performance has been in the toilet for me. They claim they've mitigated it but when 4.0 first dropped CC was really impressive, and now I constantly have to babysit it because any time it hits a challenge it'll just stop trying and make a simple toy version and declare false victory. If I don't catch it and I let it build on top of that bullshit, things get nasty in a hurry. It's a shame because the p…

Yes, this. I feel like I’m going crazy. I pay for the extra Opus usage and I keep checking the model switcher to see if it has automatically switched to Sonnet. It has not. I just have a lot more experiences of it feeling anecdotally dumb lately.

Why not Gemini CLI tho?

Interesting, the new model's prompt is ~half the size (10KB vs. 23KB) of the previous prompt[0][1]. SWE-bench performance is similar to normal gpt-5, so it seems the main delta with `gpt-5-codex` is on code refactors (via internal refactor benchmark 33.9% -> 51.3%). As someone who recently used Codex CLI (`gpt-5-high`) to do a relatively large refactor (multiple internal libs to dedicated packages), I kept running in…

So you're all saying suddenly codex cli w gpt 5 codex is better than claude code? Hard to believe

People are using claude code + glm models as alternative too, some complaints flying around.
