I'm happy to pay the same right now for less (on the max plan, or whatever) -- because I'm never running into limits, and I'm running these models near all day every day (as a single user working on my own personal projects).
I consistently run into limits with CC (Opus 4.5) -- but even though Codex seems to be spending significantly more tokens, it just seems like the quota limit is much higher?
I noticed I am not hitting limits either. My guess is OpenAI sees CC as a real competitor/serious threat. Had OAI not given me virtually unlimited use I probably would have jumped ship to CC by now. Burning tons of cash at this stage is likely Very Worth It to maintain "market leader" status if only in the eyes of the media/investors. It's going to be real hard to claw back current usage limits though.
If you look at benchmarks, the Claude models score significantly higher intelligence per token. I'm not sure how that works exactly, but they are offset from the entire rest of the chart on that metric. It seems they need less tokens to get the same result. (I can't speak for how that affects performance on very difficult tasks though, since most of mine are pretty straightforward.)
So if you look at the total cost of running the benchmark, it's surprisingly similar to other models -- the higher price per token is offset by the significantly fewer tokens required to complete a task.

...With the obligatory caveat that benchmarks are largely irrelevant for actual real world tasks and you need to test the thing on your actual task to see how well it does!
I am on the $20 plan for CC and Codex, I feel like a session of usage on CC == ~20% Codex usage / 5 hours in terms of time spent inferencing. It has always seemed way more geneous than I would expect.
