I've been using a lot of Claude and Codex recently.

One huge difference I notice between Codex and Claude code is that, while Claude basically disregards your instructions (CLAUDE.md) entirely, Codex is extremely, painfully, doggedly persistent in following every last character of them - to the point that i've seen it work for 30 minutes to convolute some solution that was only convoluted because of some sentence I threw in the instructions I had completely forgotten about.

I imagine Codex as the "literal genie" - it'll give you exactly what you asked for. EXACTLY. If you ask Claude to fix a test that accidentally says assert(1 + 1 === 3), it'll say "this is clearly a typo" and just rewrite the test. Codex will rewrite the entire V8 engine to break arithmetic.

Both these tools have their uses, and I don't think one approach is universally better. Because Claude just hacks its way to a solution, it is really fast, so I like using it for iterate web work, where I need to tweak some styles and I need a fast iterative loop. Codex is much worse at that because it takes like 5 minutes to validate everything is correct. Codex is much better for longer, harder tasks that have to be correct -- I can just write some script to verify that what it did work, and let it spin for 30-40 minutes.

I haven’t used Claude Code much, but I found Codex extremely frustrating. It doesn’t pay attention to anything in AGENTS.md, it’s completely incapable of removing code and is frustratingly defensive.

If you use it, the codebase constantly grows. Even when you explicitly instruct it to remove something, you always end up with more lines of code in the project than before the instruction. Also (I used it for Python and TypeScript) the code was littered with getattr(...), .get(...), isinstance(...), and TypeScript equivalents (typeof, ...). Even though I religiously type‑annotate everything.

What's wrong with hallucinogenic LSD?
alefnula · 3 years ago
We live in a society that defines itself not in terms of what it is but in terms of what it's not. We are not decent and kind human beings; we are not racists or not homophobes. We can't just not care; we have to be atheists. Even with bad stuff: We are not victim blamers and choice deniers; we are anti-abortionists.

And the products marketed to us are just a reflection of what we are. Gluten-free bread. Sugar-free drinks. Non-hallucinogenic LSD. No THC weed. Low-fat milk. Etc.

Everything is becoming defined in terms of what it's not.

I recall there being no correlation between attending Montessori schools and later success in life.

Eventually, kids figure out how to use a knife, or not crap their pants.

Early education is about social and emotional development.

I opted to stick my kids in a foreign language immersion program instead.

Can you share the link to the study you're referring to? I will soon be choosing a school for my kid, and I'm very curious to see if there are any actual differences in outcomes. All the studies I found say there are. (For example https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5670361/)

I'm surprised that no one is commenting on macros. For me, that is the most exciting feature! It'll make writing code so much more enjoyable and avoid all of the code generation happening at the moment.

But maybe I'm the only one who's bothered with code generation :D
