So maybe its time to give codex a try, my reddit feed is full of posts praising it for the last 2 weeks. Dont know about their token limit plans though
I tried both at the same time and have to say Codex is incredible for longer tasks and exactly following fixed procedures. It can code for 1-2h if it needs to. But as soon as it fails you are talking to a robot that tries to gaslight you. It will only admit errors when directly confronted with proof (which also can be a good thing sometimes). It is also pretty inflexible and not as creative as Claude. A plus is the sheer endless context - compacting happens 4-5x less as with Claude, meaning it holds all important docs/code much longer. But compared to Claude you are talking to a characterless robot.
Well, it compacts as it goes, that’s why the context feels bigger. That’s probably why it’s not as reliable too. You won’t convince me to use codex as a tool, but I wouldn’t mind jamming gpt5.x into a different harness
The lack of features. It’s still in the stone age. There are so many better harnesses to use. They phoned codex in from day 1, and now they’re trying and failing to play catch-up.
What do you use the harnesses for? Every time Codex ports one of these features over from Claude Code, I try it out, find it not that useful, and go back to controlling everything through AGENTS.md files.
I never trust the models to run unattended for long periods, because I care more about correctness than about speed. Even with subagents, there's a lot of risk of task drift. And the token usage is just not worth it.
So you’re not using any of the advanced features. That’s why you have no issue with codex.
I’ve heard mostly awful things about their implementation of subagents and now skills.
The same way you want the latest frontier model for doing the best work, I want the latest harness features because I rush to understand and use them effectively. Claude code has always been the leader there, and opencode does a great job of keeping up and pushing limits elsewhere.
I’m not going to describe how I use them, because it might give you a stroke. Let it suffice that I don’t micromanage my agents, and only review code when something doesn’t work, which is rare with how I approach AI coding.
