I am going to pause Opus 5.5 use. I find it really scummy business practice. We trust them that what is behind the string &quot;opus-5-5&quot; is consistent and what we signed up for. Of course behind the scenes they can do whatever they like and serve whatever model they like under that string. It is a scummy and deceptive business practice though.
