Ask HN: Is Codex really on Par with Claude Code?

kypro

GPT-5.4 Pro is very good, at the very least comparable with Opus 4.6. Some people on my team have switched to Codex in the last month citing that it's currently slightly better. If you have a good workflow with CC I wouldn't switch, but if you're deciding whether to use one or the other, maybe give Codex a shot.

Yes, even better sometimes.

I've been using Claude Code as my primary agent orchestration tool for a few weeks now. Running cron-style loops for browser automation through a remote Playwright instance. Haven't tried Codex at this depth yet, but from what I've seen it's more focused on code generation while Claude Code is more of a general-purpose agent runtime. The things that make Claude Code powerful for me are the persistent session with tool access, the ability to run background tasks on schedules, and the hook/skill system for customization. If Codex matches that plus adds better async execution (Claude Code's scheduled tasks die when the session ends), it could be compelling. But for now Claude Code handles my use case better than anything else I've tried.

I’ve mostly switched to Codex (GPT-5.4 high) over Claude Code (Opus 4.6) in the last few weeks. I think my style of workflow and prompting seems to generate a bit better results with it. I have a thin CLI based issue tracker and an associated skill that I use instead of markdown files and Codex does a better job of interacting with it and updating existing tasks over time whereas Claude Code tends to create duplicate tasks with slight changes. I find the code quality of both to be pretty on par with some style differences; Claude has been leaving very verbose comments as of late I do slightly prefer the Codex app over the Claude Code TUI and Visual Studio Code integrations.

Claude has become pretty slow and in the last couple of weeks, so I switched to codex. Codex code can be quite sloppy, so it's worth doing multiple review passes.

I just recently shifted to codex since i got frustrated with the token usage which did not allow me to get my work done. Here's my honest opinion i think with the right configs codex does a very good job, like cc is better in terms of quality of code generated but codex seems to understand everything way better, and you can improve your code quality if just read through it once.
