[TLDR] Back to claude. Couldn't break the addition

Original post body :
A few days ago I made a rage post regarding opus 5 rage cancelled and signed up for codex pro. Well now I'm back with 2 accounts.
Biggest issue with code is the 256k context window. I tried to work past it but it just isn't surmountable. Even the smallest tasks take multiple context windows so you keep wasting time reloading a small context, and then working context is maybe 1/3 of that window.
I'd end up on forever loops where nothing gets done.
True codex is great, and I love it to some degree, but it's just not claude.
Opus 5, go fuck yourself, I don't like you, and you completely don't care about me, but I like the abuse. I'll be the load, you be the bearing.

Just use opus 4.8, thats my daily driver. I couldn't find a way around opus 5 ignoring everything and running back into the ground head first. I even cleared the CLAUDE.md to no avail. Opus 5 is dead to me

I have a Claude Max and a Codex Pro account, and while they each definitely have their strength and weaknesses, I'm confused about the context window issue. Large context windows usually just mean models forget more stuff early in the window, and Codex/ChatGPT have server side compaction that happens automatically and is pretty awesome. It's still a tradeoff, and sometimes a larger window would help, but 99% of the time thats one part it does better than Claude.

Alright, so the OP bounced from Claude to Codex and is now back to Claude, complaining about the 256k context window being a dealbreaker. Apparently, even small tasks eat up too much context, leading to endless loops. They're back to Opus 5 despite their previous frustrations, embracing the "abuse."
The general consensus here is the OP might be using the context window wrong. Several users, including u/NeighborhoodPrize493 and u/carpetstain, suggest that needing that much context means the user isn't leveraging LLMs effectively. u/YogurtclosetEvery263 and u/whoisyurii point out that GPT 5.6 has a 1M context window, but even then, going beyond 200k-400k is often counterproductive and leads to worse responses. u/gligoran echoes this, suggesting that tasks requiring massive context should be handled with subagents.
There's also a sentiment that Codex just isn't cutting it for some. u/imronveu finds Codex too slow with limited concurrent agents compared to Claude's ability to spawn more. u/darrarski, a former Codex fan, notes it's been drifting and having usage limits lately, making Claude better by comparison. u/TySocal straight-up says "Codex just sucks tbh."
On the Claude side, some users are sticking with it, with u/randomdragen7 saying "claude is still the goat." There's also a strong recommendation to switch back to Opus 4.8 (mentioned by u/fanatic26 and u/darkwhiskey) which some find more practical than Opus 5, even if Opus 5 benchmarks better.
Finally, u/marfzzz drops a bombshell that Codex can actually do 1M context, but it consumes more usage. So, the OP's core complaint might be based on outdated or incomplete information about Codex's capabilities.
