This is something I notice often when using these tools (if this is what you are referring too). Like they will grep entire code bases to search for a word rather than search by symbol. I suppose they don't care to fix these types of things as it all adds up to paid tokens in the end.

We have 50 years worth of progress on top of grep and grep is one of the worse ways to refactor a system.

Nice to see LLM companies are ignoring these teachings and speed running into disaster.

Just to provide another datapoint - tried codex September / October after seeing the glowing reviews here, and it was, all in all, a huge letdown.

It seems to be very efficient context-wise, but at the same time made precise context-management much harder.

Opus 4.5 is quite a magnificent improvement over Sonnet 4.5, in CC, though.

Re tfa - I accidentally discovered the new lsp support 2 days ago on a side project in rust, and it’s working very well.

It goes like this:

Codex is an outsourcing company, you give specs, they give you results. No communication in between. It's very good at larger analysis tasks (code coverage, health etc). Whatever it does, it does it sloooowwwllyyy.

Claude is like a pair programmer, you can follow what it's doing, interrupt and redirect it if it starts going off track. It's very much geared towards "get it done" rather than maximum code quality.

I’m basically only using the Codex CLI now. I switched around the GPT-5 timeframe because it was reliably solving some gnarly OpenTelemetry problems that Claude Code kept getting stuck on.

They feel like different coworker archetypes. Codex often does better end-to-end (plan + code in one pass). Claude Code can be less consistent on the planning step, but once you give it a solid plan it’s stellar at implementation.

I probably do better with Codex mostly due to familiarity; I’ve learned how it “thinks” and how to prompt it effectively. Opus 4.5 felt awkward for me for the same reason: I’m used to the GPT-5.x / Codex interaction style. Co-workers are the inverse, they adore Opus 4.5 and feel Codex is weird.

I've gone it works wonderful for 5.2. I think chatgpt plus is at the top of the weekly AI rolling wars. Most bang for the buck.

My theory is that even if the models are frozen here, we'll still spend a decade building out all the tooling, connections, skills, etc and getting it into each industry. There's so much _around_ the models that we're still working on too.

> Shows how much more work there is still to be done in this space.

This is why I roll my eyes every time I read doomer content that mentions an AI bubble followed by an AI winter. Even if (and objectively there's 0 chance of this happening anytime soon) everyone stops developing models tomorrow, we'll still have 5+ years of finding out how to extract every bit of value from the current models.

Cobbler’s children…
