That has me quite tempted. In general, I stay under the Plus limits, but I do watch my consumption. I could use `/fast` mode all of the time, with extra high reasoning, and use gpt-5.4-pro for especially complex tasks. It wasn't worth 10x the price to me before, but 5x is approachable.
I think you currently can't use pro inside codex, or can you?
That's an odd choice. I wonder why.
Good question. I'd hope/expect that you could, but that doesn't mean much.
no you can't use pro in the harness.
That is disappointing. I find myself mostly using Codex these days. ChatGPT still for one off questions/prompts, but usually complex problems require context, like files and tools I already have on my system, and Codex is way better for that.
