Codex/GPT5.4 is just superior to Opus4.6 for coding. I swear it costs me 1/2 of the tokens to achieve the same results and it always follows through the plan to completion compared to Opus that takes shortcuts and sweeps things under the rug until I discover them through testing.

I'm not accusing anyone of foul play and I don't have financial interests in either company, but it feels like "something" within Code Claude/Anthropic models is optimizing to make you spend more tokens instead of helping you complete the task.
