I can't afford/allow for ultra pricing for personal projects, but Pro runs through in about two days of casual usage for me. I've paid for extra credits, but my god are those not worth the price.
I would love to pay for a sub that's between Pro and Ultra.
Although using another provider for the secon sub is probably a better idea since having a different model doing review would uncover more issues than asking the same model that generated the code..
Both take a long time. It used to be that antigravity was much faster than codex, but with recent releases it is substantially slower.
Inspecting the agents communication in teamwork, there seems to be an overwhelming amount of ceremony: BRIEF.md, specialized roles, multiple rounds of checking. Is all that necessary? Codex also uses agent “swarms” but unless they’ve hidden how the sausage is made, it doesn’t seem so heavyweight.
