You should still do this because claude and codex are good at different things. Once you have claude write build plans and codex rip it to shreds and iterate, you'll wonder how you ever AI-coded before.
That's just throwing away money, $100 Codex will go back to 5x from 10x on May 31
Even if so (granted, if the mysterious "x" isn't also adjusted), I bet codex usage limits on $100 plan would still be more generous than Anthropic's $200.
I never even gotten close to token anxiety on codex $200 and it's essentially working 24/7. This was never possible with Anthropic since Opus came out.
I think gpt 5.6 is coming out today so might wanna wait
