this was the first UI by codex, the model was very fast with only ~7min, claude code was ~20min

this is the "proof": https://gist.github.com/eliebak/e1f30ab973ee3ef41cba275d65c3b2cb

final plot is from the research with claude code, this was the output from codex

> leading means shipping feature first, user experience is not only about this btw, should be more clear that this is not a dunk on codex (or cc) just some visualization i made for myself and sharing here

also weird behavior where codex compacted after only ~3min, i don't think this necessarily bad (might be the opposite if it's smart!), just surprised
