opus 4.7 is a big disappointment for me
unlike gpt-5.5, it feels more like a distill or smaller version of a bigger model
maybe mythos?
however, it needs far more reasoning tokens than earlier opus models, which makes it look like anthropic is moving in the wrong direction
THIS GUY SWITCHED FROM CLAUDE CODE TO CODEX AND THE DIFFERENCE IS EMBARRASSING
he was on the $200 claude code plan. tried to merge 2 entities which required a database migration. changing server, making tests pass, changing SDK, admin, and storefronts
claude code failed for 2 straight days
it was deleting things it shouldn't, stopping on its own to ask if it could proceed even though he couldn't have been clearer, deviating from explicit instructions
then claude literally stated that it was MAD and ANNOYED
the AI told him it was frustrated. and started coding like it too. just hacking things together at all costs trying to force a solution
he decided to try codex 5.5 on the $100 plan
codex merged the backend, made the tests pass, ran the init scripts, then used playwright to test admin and actual consumers. back to back. one shot. 10,000 lines of code refactored clean
his words: "the comparison can't be put into percentages. claude code was around 5% there and codex nailed it"
he said codex talked extremely clear, followed natural logic, and communicated like old claude code used to
a company that wanted to destroy engineers will be forced to admit their main tool didn't do a good enough job to write itself
rn, claude code is losing its most loyal power users one bad session at a time
anthropic and openai had a clear pattern:
oAI released a top model, then anthropic quickly followed with something equal to or better
but after gpt-5.5 was widely praised, opus 4.7 was met with criticism, mainly because of stricter limits, less trust, and no reasoning-effort control
and signs anthropic turning down performance to save compute
After using Claude Opus 4.7 and ChatGPT 5.5 Heavy side by side all week for identical tasks, I will say that it is painfully, dreadfully, and clearly obvious that ChatGPT is the smarter and more consistent model.
Claude can be clever, but it goes full derp quite often. It forgets to use web search and reasoning.
It's still a good writer, researcher, and explainer.
But yeah, it's no contest for my work (post-labor economics). ChatGPT is far and away the superior model.
I still use both in parallel for identical tasks because occasionally Claude produces a banger or says things a bit more user-friendly (ChatGPT still gets gummed up with pretentious academic language too much). But Claude also just tries to be too clever.
So I can see how both models handle the same concept/problem/passage and usually triangulate the best way to frame it.
anthropic has had a rough month:
rate limits annoyed users
opus 4.7 isn't really that popular
accidentally leaked "claude code" code
compute shortage made the limits worse
tested removing claude code from the cheap plan
really bad timing, especially with openai pushing hard
Anthropic: held an entire conference to announce doubled 5-hour limits while weekly limits stayed the same
OpenAI: we couldn’t invite everyone to a party, so here’s 10x limits for the month
Battle with Claude Code on Opus 4.7 for an hour over an issue that feels trivial but it just can’t get right.
Ask Claude to write me a handoff so I can take the same issue to Codex.
Codex on GPT-5.5 gets it right on the first try.
This has basically been my workflow lately.
Next time. Can you please just tell us that you're struggling with compute and have to stop subscriptions + do some rate limiting?
While some people will get mad (entitled pricks) most of us would understand and accommodate (albeit a little sour)
Instead this spiel of rug pulling services, free trial pro instead of claude code, lobotomizing the newest release instead of full throttle, banning users and focusing compute on b2b for moneyz.
A little transparency goes a long way with trust and now people found out anyway that Anthropic was struggling (like OpenAI did some time ago too)
You do you, but... c'mon.
everyone at anthropic acting like they removed the rate limits altogether
you just doubled the 5 hour window...
i never heard anyone complain about the 5 hour window limits even once
it's the weekly limits that are the most annoying
