GPT5 honestly feels like shrinkflation.
Getting frustrated with GPT5. I've being using GPT to keep track of food intake but since going to 5 it has been all over the place. I then tried the Google one on my phone and it told me to call a mental health charity after it suggested I was getting too much protein and I questioned it.
Yes, 5 has forgotten a chunk of some formatting rules I've been using, which took a little while to fix, but it's still better than doing it by hand.
They have made a total fudge of the release of this "new" GPT5, as evidenced by the frantic backpedalling they are doing on X.
After all the hyping up they did it's basically a model switcher which has properly screwed up the way the existing products worked.
Forgetting stuff suddenly mid conversation, hot and cold censorship, split personality syndrome, miniscule levels of context retention.... using GPT5 is like playing the lottery in terms of output quality.
