I’m threw a few hours at Codex the other day and was incredibly disappointed with the outcome…
I’m a heavy Claude code user and similar workloads just didn’t work out well for me on Codex.
One of the areas I think is going to make a big difference to any model soon is speed. We can build error correcting systems into the tools - but the base models need more speed (and obviously with that lower costs)
Any experience w/ Haiku-4.5? Your "heavy Claude code user" and "speed" comment gave me hope you might have insights. TIA
