GPT-5.4 High is considered the recommended, most balanced model for coding, while xhigh is often deemed too verbose and prone to overthinking.

5.4 is worse than 5.3 codex for me. There's some cases where 5.4 edges out, its real good at intuition, but it often affects more than you asked for and breaks things.
