I had far more hallucinations with 4.7 than 4.6.
I'll try it again after a few more months for them to get it right, but 4.6 is what changed my mind on LLMs as a tool, and 4.7 felt like a step backwards, so for now I'm sticking with something that has delivered me value, instead of arguing with a model ostensibly better that was making shit up 1 - 2 times a day. It was really disappointing.
I can give examples if needed, I screenshotted the most aggravating ones, but what worries me is which ones I didn't recognise.
