  "textContent": "So I can agree with that, my experience is also with GPK 5.4, it doesn’t matter if you work with low or high, it doesn’t matter, at just under an hour, 5 hours are over and whether you work with low or high reasoning, when the model says I don’t need the power, it doesn’t matter if it’s longer or shorter, it doesn’t make a difference. In the real software development area, just a few minutes, if you differ from low to high reasoning, so you can always run on high, I’ll probably run the days on extra high and see if extra high also lasts about 45 to 60 minutes. And the other recommendation, for example, to switch to 5.4 mini is also pretty banana, because 5.4 just produces less cool results and you need longer and it just doesn’t work for you, so the only option is to switch to 5.3.",
