I went to 4.7, didn't have a choice, found it unsatisfactory, then Claude quietly added in the option to use 4.6, so I'm back on 4.6, and I'm not the only one in my company.

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.

How did you manage to do that?

/model command returns only 4 choices for me: Opus 4.7, two Sonnet options and Haiku.
