Over the last couple of months ChatGPT has become less and less responsive if you do anything very complex with it. It does not follow instructions, tells you it has completed a step when it hasn't done anything, and doesn't deliver the end product when it has finished.
And even worse, after you have worked with it several hours to get the work done, it cannot deliver the finished product to you. It tells you "The system is blocking downloads, which means I cannot provide the file directly." It then offers alternative methods of delivery. But then gives you the same error message for each of the alternative methods it offers.
I am looking for a good replacement that actually works, the way ChatGPT worked up to a couple of months ago. I don't mind paying for it. I switched to ChatGPT Plus for two months, at $200 per month, thinking that was the problem and ChatGPT would work better at the higher price level. So, I wasted $400 as there was no improvement.
