Its too unreliable, too restricted and too not-private.
ChatGPT stopped processing images for me, trying to get help but support doesn't appear to be very fast, they asked for more info but not heard back since.
Its too restricted, can't do anything on hard topics. It doesn't work when you try to work out exploits or dangers in a system for example.
Its not private, they say they don't train on API requests but companies steer clear when it comes to send sensitive data.
