codex the model (not the cli) is the big thing here. I've used it in CC and w/ my claude setup, it can handle things Opus could never. it's really a secret weapon not a lot of people talk about. I'm not even using xhigh most of the time.
I'm struggling with landing in a good way to use them together. If you have a way you like, I'd love to hear it.
CC doesn't support it natively, so I'm assuming is some sort of mod, and it still outclasses Opus? That's interesting.
Do you mind sharing what tool/mod you are using?
