@finbarrtimbers @natolambert Codex is actually lowkenkinuinely better than opus

finbarr@finbarrtimbers

@natolambert It’s completely changed my relationship towards Claude (Code). I feel really weird using it. Going to try to shift my usage to Codex. I’ll see if it sticks this time- I’ve tried to switch in the past but kept coming back to CC’s better interface.

yeah exactly the same, it's been quite a weird day for me so far (EU time), there is little things like codex being fast which make my brain telling me the output will be bad 😂

oh and also i miss quite a lot claude for reading paper i miss a lot claude, i guess could still use it but it just feels super weird :(

@finbarrtimbers @natolambert if you havent tried it on medium reasoning (for day to day stuff) you should that's what finally allowed me to make the leap. high for some things. never xhigh

@finbarrtimbers @natolambert also did this previously - fwiw I feel that you can work around some of the differences once you get more used to codex

@yacineMTB @finbarrtimbers Not for helping edit text, making talks, and a bunch of other stuff I do. But yeah I use codex a ton already
