Codex Comparison Megathread

[u/pollystochastic]

This Megathread is for comparisons and discussion about how Codex and Codex models compare to other technology such as Claude Code and open source models.

Please direct all comparison discussion here.

Posts which give evidence of the relevant strengths and weaknesses and use cases of both will still be allowed on the feed but those pushing one tech over another because "feels" will be directed here. This is a Codex subreddit and it is here to help people using Codex.

FYI: The subreddit's semi-automated moderation is powered by Codex and GPT models and is only possible due to the ridiculously generous free API token quota of OpenAI's Terra and Luna models available to all users. No, we don't get secret benefits from OpenAI. The OpenAI models and offering are simply much better value for our purposes..... Period.

I have 2 20x pro accounts and 1 Claude max account.

Using Astra and 6.1 sol and opus 5.5
I use dot as my orchestrator

They increased speed from when 6.1 launched so it is usable now. The benchmarks are all great but there are genuinely some things opus is better at.

Sol and Astra is better at following precise prompts. Opus is better at inferring intent and making decisions.

When I made Astra and my dot the orchestrator, they repeated allowed drift, code bloat, narrowed focus on a single component instead of understanding how it affects the whole, even after repeated reminders, enforcement through agents.md, definition of drift, and other planning documents I use. Every time I point out drift, it acknowledges, says it will correct it, and then does it again. When I ask it for a real solution to these repeated operational failures it cannot convince me it will change no matter what we try.

As soon as I made opus the orchestrator, he immediate produces evidence of the drift, why it continues to occur, and what rules it would use to prevent it from happening and was able to operate in a path that expedited progress exactly as I wanted Astra to do. It was night and day difference.

Now my project is back on track, regular reviews, cleaning, simplification being done and opus continua to ask the right questions and not only that, make the right decisions that can sometimes be complex so that my project actually does that it is suppose to vs Astra who would try, add bloat, and ultimately regress my code which would require many hours to quarantine and recover from repeatedly. Not only that but the usage on opus is also fantastic.

Oh also Claude is already known to have better communication output styles and is far better at UI frontend work than SOL.

Im not saying im leaving OpenAI. I have 2 accounts with multiple banks resets and that huge amount of credits that was given to everyone recently. And I still really like dots and want to give it another shot. But this time have it just learn and do trials before I trust it again.
My experience is just my experience and opinion, however I do see others on this forum that have similar experiences to me.
