Opus 4.6 has been out for less than a month. If it was a big shift surely we'd see a massive difference over 4.5 which was november. I think this proves the point, you're not seeing seisimic shifts every 3 months and you're not even clear about which model was the fix.

Shifting, maybe. But shuffling deck chairs every 3 months.
